Clin. manifestations of leishmaniasis range from self-healing, cutaneous lesions to fatal infections of the viscera. With no preventative Leishmania vaccine available, the frontline option against leishmaniasis is chemotherapy. Unfortunately, currently available anti- Leishmania drugs face several obstacles, including toxicity that limits dosing and emergent drug resistant strains in endemic regions. It is, therefore, imperative that more effective drug formulations with decreased toxicity profiles are developed. Previous studies had shown that 2-(((5-Methyl-2-thienyl)methylene)amino)-N-phenylbenzamide (also called Retro-2) has efficacy against Leishmania infections. Structure-activity relationship (SAR) analogs of Retro-2, using the dihydroquinazolinone (DHQZ) base structure, were subsequently described that are more efficacious than Retro-2. However, considering the hydrophobic nature of these compounds that limits their solubility and uptake, the current studies were initiated to determine whether the solubility of Retro-2 and its SAR analogs could be enhanced through encapsulation in amphiphilic polymer nanoparticles. We evaluated encapsulation of these compounds in the amphiphilic, thermoresponsive oligo (ethylene glycol) methacrylate-co-pentafluorostyrene (PFG30) copolymer that forms nanoparticle aggregates upon heating past temperatures of 30°C. The hydrophobic tracer, coumarin 6, was used to evaluate uptake of a hydrophobic mol. into PFG30 aggregates. Mass spectrometry anal. showed considerably greater delivery of encapsulated DHQZ analogs into infected cells and more rapid shrinkage of L. amazonensis communal vacuoles. Moreover, encapsulation in PFG30 augmented the efficacy of Retro-2 and its SAR analogs to clear both L. amazonensis and L. donovani infections. These studies demonstrate that encapsulation of compounds in PFG30 is a viable approach to dramatically increase bioavailability and efficacy of anti-Leishmania compounds This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Product Details of 38215-36-0).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Product Details of 38215-36-0

Sorafenib-Loaded PLGA-TPGS Nanosystems Enhance Hepatocellular Carcinoma Therapy Through Reversing P-Glycoprotein-Mediated Multidrug Resistance was written by Tang, Maomao;Huang, Yuzhe;Liang, Xiao;Tao, Yaotian;He, Ning;Li, Zhenbao;Guo, Jian;Gui, Shuangying. And the article was included in AAPS PharmSciTech in 2022.HPLC of Formula: 38215-36-0 The following contents are mentioned in the article:

Multidrug resistance (MDR) is a key determinant for hepatocellular carcinoma chemotherapy failure. P-glycoprotein is one of the main causes of MDR by causing drug efflux in tumor cells. In order to solve this thorny problem, we prepared a sorafenib-loaded polylactic acid-glycolic acid (PLGA) – D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) nanoparticles (SPTNs). SPTNs were successfully synthesized through an ultrasonic emulsion solvent evaporation method with a favorable encapsulation efficiency of 90.35%. SPTNs were almost spherical in shape with uniform particle size (215.70 ± 0.36 nm), narrow polydispersity index (0.27 ± 0.02) and neg. surface charge (-26.01 ± 0.65 mV). In the cellular uptake assay, the intracellular coumarin-6 (C6) fluorescence of TPGS component-based PLGA nanoparticles (C6-PTNs) was 1.63-fold higher relative to that of PVA component-based PLGA nanoparticles (C6-PVNs). The half-maximal inhibitory concentration and apoptosis ratio of SPTNs against HepG2/MDR cells were 3.90 μM and 75.62%, resp., which were notably higher than free SF and sorafenib-PLGA-PVA nanoparticles (SPVNs). The anti-drug efflux activities of SPTNs were assessed by the intracellular trafficking assay using verapamil as a P-gp inhibitor. SPTNs could effectively inhibit the drug efflux in tumor cells detected by flow cytometry, and suppressed relative MDR1 gene as well as P-glycoprotein expression in tumor cells. Attributed to the MDR reversion effect of SPTNs, the in vivo antitumor efficacy experiment showed that SPTNs significantly inhibited the tumor growth of HepG2/MDR xenograft-bearing nude mice, and obviously reduced the toxicity against liver and kidney compared with SF treatment. In summary, SPTNs, as highly efficient and safe antitumor nano delivery systems, showed promising potential for hepatocellular carcinoma therapy through reversing P-glycoprotein-mediated MDR.

BODIPY dyes possess favorable optical properties for a variety of applications including in vivo and in vitro diagnostics. However, their utilization might be limited by their water insolubility and incompatibility with chem. modifications, resulting in low aggregation stability. Here, we outline the route for addressing this issue. We have demonstrated two approaches, based on dye entrapment in micellar coordination clusters (MCCs); this provides a general solution for water solubility as well as aggregation stability of the seven BODIPY derivatives These derivatives have various bulky aromatic substituents in the 2,3,5,6- and meso-positions and can rotate relative to a dipyrrin core, which also provides mol. rotor properties. The mol. structural features and the presence of aromatic groups allows BODIPY dyes to be used as “supporting mols.”, thus promoting micelle-micelle interaction and micellar network stabilization. In the second approach, self-micellization, following BODIPY use, leads to MCC formation without the use of any mediators, including chelators and/or metal ions. In both approaches, BODIPY exhibits an excellent optical response, at a concentration beyond its solubilization limit in aqueous media and without undesired crystallization The suggested approaches represent systems used to encapsulate BODIPY in a capsule-based surfactant environment, enabling one to track the aggregation of BODIPY; these approaches represent an alternative system to study and apply BODIPY′s mol. rotor properties. The stabilized compounds, i.e., the BODIPY-loaded MCCs, provide a unique feature of permeability to hydrophilic ligand-switching proteins such as BSA; they exhibit a bright “turn-on” fluorescence signal within the clusters via macromol. complexation, thus expanding the possibilities of water-soluble BODIPY-loaded MCCs utilization for functional indicators.

Aortic dissection (AD) is a life-threatening disease featured by the dissection of intimal layer and the formation of a blood-filled false lumen within the aortic wall. Recent studies revealed that the formation and progression of AD lesions is closely related to vascular inflammation and macrophage infiltration. However, the potential efficacy of anti-inflammatory therapy on the prevention and treatment of AD has not been extensively investigated. Herein, we proposed a biomimetic anti-inflammatory liposome (PM/TN-CCLP) co-loaded with curcumin and celecoxib (CC), modified with cell-penetrating TAT-NBD fusion peptide (TN), and further camouflaged by isolated macrophage plasma membrane (PM), as a potential nanotherapy for AD. In vitro results showed that PM/TN-CCLP exhibited low cytotoxicity and elevated cellular uptake by inflammatory macrophages, and prominently inhibited the transendothelial migration, inflammatory responses and ROS generation of macrophages. Moreover, the PM/TN-CCLP treatment significantly prevented the H₂O₂-induced smooth muscle cell apoptosis. In vivo experiments were performed on the acute and chronic AD mouse models, resp. The results verified the elevated accumulation of PM-camouflaged liposome at the aorta lesions. Further, the anti-inflammatory liposomes, especially PM/TN-CCLP, could reduce the rupture rate of dissection, prevent the loss of elastic fibers, and reduce MMP-9 expression as well as macrophage infiltration in the aortic lesions. Notably, as compared with free drugs and TN-CCLP, the PM/TN-CCLP treatment displayed the longest survival period along with the minimal aortic injury on both acute and chronic AD mice. Taken together, the present study suggested that the macrophage-biomimetic anti-inflammatory nanotherapy would be a promising strategy for the prevention and therapy of aortic dissection.

The present work aimed to develop topical solid lipid nanocarriers (SLN) loaded hydrogel of apremilast (API) for psoriasis therapy to minimize the systemic adverse effects. The quality by design approach was implemented for the optimization of API loaded SLN using Box-Behnken design. SLN were prepared using hot emulsification followed by size reduction using probe sonication. The size and entrapment were found to be 167.70 nm ± 1.5 (0.238 PDI) and 63.84 ± 0.93%, resp. The FESEM images of SLN dispersion portrayed the spherical shape of nanocarriers. The in vitro drug release of SLN dispersion showed extended-release up to 18 h and followed the Korsmeyyar-Peppas model with a regression value of 0.958 (n = 0.330), and Akaike index criteria was 63.69. In vitro cell line study, the MTT assay depicted the formulation excipients had minimal effect, and high internalization was observed with SLN dispersion (1.4-fold). The Ct value reduction in the relative expression of TNF-α miRNA was 3-fold higher with SLN dispersion compared to the pos. control. The ex vivo skin retention and dermal distribution study by Coumarin-6 dye depicted an increase in permeation and retention with SLN formulation compared to free drug-loaded gel. The dermato-pharmacokinetic study of SLN formulation exhibited 2-fold higher drug retention in the epidermis and 5-fold higher in the dermis compared to free drug. This were stable for 3 mo without significant changes. The results suggest that API loaded SLN can be utilized for topical delivery for effective treatment of psoriasis by targeting skin layers. The API loaded SLN based topical gel formulation showed improved permeation, skin deposition and prolonged release compared to conventional preparation The designed preparation can signify a potential alternative for psoriasis treatment after clin. evaluation in near future.

Solubilized ubiquinol for preserving corneal function was written by Naguib, Youssef W.;Saha, Sanjib;Skeie, Jessica M.;Acri, Timothy;Ebeid, Kareem;Abdel-rahman, Somaya;Kesh, Sandeep;Schmidt, Gregory A.;Nishimura, Darryl Y.;Banas, Jeffrey A.;Zhu, Min;Greiner, Mark A.;Salem, Aliasger K..

Defective cellular metabolism, impaired mitochondrial function, and increased cell death are major problems that adversely affect donor tissues during hypothermic preservation prior to transplantation. These problems are thought to arise from accumulated reactive oxygen species (ROS) inside cells. Oxidative stress acting on the cells of organs and tissues preserved in hypothermic conditions before surgery, as is the case for cornea transplantation, is thought to be a major reason behind cell death prior to surgery and decreased graft survival after transplantation. We have recently discovered that ubiquinol – the reduced and active form of coenzyme Q10 and a powerful antioxidant – significantly enhances mitochondrial function and reduces apoptosis in human donor corneal endothelial cells. However, ubiquinol is highly lipophilic, underscoring the need for an aqueous-based formulation of this mol. Herein, we report a highly dispersible and stable formulation comprising a complex of ubiquinol and gamma cyclodextrin (γ-CD) for use in aqueous-phase ophthalmic products. Docking studies showed that γ-CD has the strongest binding affinity with ubiquinol compared to α- or β-CD. Complexed ubiquinol showed significantly higher stability compared to free ubiquinol in different aqueous ophthalmic products including Optisol-GS corneal storage medium, balanced salt solution for intraocular irrigation, and topical Refresh artificial tear eye drops. Greater ROS scavenging activity was noted in a cell model with high basal metabolism and ROS generation (A549) and in HCEC-B4G12 human corneal endothelial cells after treatment with ubiquinol/γ-CD compared to free ubiquinol. Furthermore, complexed ubiquinol was more effective at lowering ROS, and at far lower concentrations, compared to free ubiquinol. Complexed ubiquinol inhibited lipid peroxidation and protected HCEC-B4G12 cells against erastin-induced ferroptosis. No evidence of cellular toxicity was detected in HCEC-B4G12 cells after treatment with complexed ubiquinol. Using a vertical diffusion system, a topically applied inclusion complex of γ-CD and a lipophilic dye (coumarin-6) demonstrated transcorneal penetrance in porcine corneas and the capacity for the γ-CD vehicle to deliver drug to the corneal endothelium. Using the same model, topically applied ubiquinol/γ-CD complex penetrated the entire thickness of human donor corneas with markedly greater ubiquinol retention in the endothelium compared to free ubiquinol. Lastly, the penetrance of ubiquinol/γ-CD complex was assayed using human donor corneas preserved for 7 days in Optisol-GS per standard industry practices, and demonstrated higher amounts of ubiquinol retained in the corneal endothelium compared to free ubiquinol. In summary, ubiquinol complexed with γ-CD is a highly stable composition that can be incorporated into a variety of aqueous-phase products for ophthalmic use including donor corneal storage media and topical eye drops to scavenge ROS and protect corneal endothelial cells against oxidative damage.

Bacteria-propelled microtubular motors for efficient penetration and targeting delivery of thrombolytic agents was written by Xie, Songzhi;Mo, Chuanfei;Cao, Wenxiong;Xie, Shuang;Li, Shang;Zhang, Zhanlin;Li, Xiaohong. And the article was included in Acta Biomaterialia in 2022.Synthetic Route of C20H18N2O2S The following contents are mentioned in the article:

Effective thrombolysis is critical to rapidly rebuild blood flow for thrombosis patients. Drug delivery systems have been developed to address inadequate pharmacokinetics of thrombolytic agents, but challenges still remain in the timely removal of blood clots regarding the dense fibrin networks. Herein, rod-shaped tubular micromotors were developed to achieve efficient penetration and thorough destruction of thrombi. By using electrospun fiber fragments as the template, urokinase (uPA)-loaded polydopamine (PDA) microtubes with surface decorated fucoidan (FuPDAuPA) were prepared at the aspect ratio of around 2. One E. coli Nissle 1917 (EcN) was assembled into one microtube to construct a FuPDAuPA@EcN hybrid micromotor through PDA adhesion and L-aspartate induction. The pharmacokinetic anal. indicates that the encapsulation of uPA into micromotors extends the half-life from 0.4 to 5.6 h and increases the bioavailability over 10 times. EcN-propelled motion elevates adsorption capacities of FuPDAuPA@EcN for more than four times compared with that of FuPDAuPA. The fucoidan-mediated targeting causes 2-fold higher thrombolysis capacity in vitro and over 10-fold higher uPA accumulation in thrombi in vivo. In the treatment of venous thrombi at mouse hindlimbs, i.v. administration of FuPDAuPA@EcN completely removed blood clots with almost full recovery of blood flows and apparently alleviated tail bleeding. It should be noted that FuPDAuPA@EcN treatment at a reduced uPA dose caused no significant difference in the blood flow rate compared with those of FuPDAuPA. The synergistic action of fucoidan-induced targeting and EcN-driven motion provides a prerequisite for promoting thrombolytic efficacy and reducing uPA dose and bleeding side effect. The standard treatment to thrombosis patient is i.v. infusion of thrombolytic agents, but the associated bleeding complications and impairment of normal haemostasis greatly offset the therapeutic benefits. Drug delivery systems have been developed to address the limitations of inadequate pharmacokinetics of thrombolytic agents, but challenges still exist in less efficient penetration into dense networks for thorough destruction of thrombi. Up to now only few attempts have been made to construct nano-/micromotors for combating thrombosis and there is no single case that antithrombosis is assisted by bacteria or cells-propelled motors. Herein, bacteria-propelled microtubes were developed to carry urokinase for efficient penetration into blood clots and effective thrombolysis. The synergistic action of bacteria-driven motion and specific ligand-induced targeting holds a promising treatment strategy for life-threatening cardiovascular diseases such as thrombosis and atherosclerosis.

Diseases of the posterior segment of the eye are difficult to treat due to lesser bioavailability of therapeutics at the posterior segment of the eye. Current clin. interventions involve administering drugs via invasive routes (Intravitreal, Retrobulbar, or Peribulbar) that bear the least patient compliance. Several nanocarriers strategies have shown a remarkable potential to deliver the loaded therapeutic to the posterior tissues of the eye. However, no one platform report was available to demarcate the most effective delivery system out of the recommended approaches. This investigation aimed at exploring a suitable and efficient non-invasive topically administrable nanocarriers system for the delivery of the drug to the posterior segment of the eye. Dexamethasone (DEX, a corticosteroid used for ocular inflammation) was selected as a model drug. The nanocarriers were formulated (size ∼ 120 nm) and studied their potential at a common platform to deliver the drug to the posterior segment of the eye. The nanocarriers were analyzed for their in vitro drug release profile in simulated tear fluid (STF) depicting sustained release of DEX up to 24 h, ex-vivo corneal permeability, using excised goat cornea, cytotoxicity potential using human retinal pigment epithelium ARPE-19 cell lines, HET CAM assay to evaluate ocular irritancy, elec. resistance measurement across monolayers of Rabbit corneal epithelial cells SIRC and ARPE-19 cells and stability profiles, real-time qPCR IL-6 gene expression in ARPE-19 inflammation model. Ex-vivo corneal permeability demonstrated that the highest percentage of DEX was permeated by DEX-NLCs and lowest by DEX-SLNs. All the nanocarriers except DEX-CUBs depicted no cytotoxicity in ARPE-19 cells. All the nanocarriers depicted the change in elec. resistance measurement across monolayers of Rabbit corneal epithelial cells SIRC and ARPE-19 cells. They were also found to reduce the levels of IL-6 in gene expression assay depicting successful in vitro delivery to ARPE-19 cells. However, only NLCs and NMFs were selected further as they demonstrated better potential to permeate after ex vivo and in vitro permeability studies. Further, in-vivo fluorescence imaging studies in Wistar rats were also performed with coumarin-6 loaded nanocarriers to deduce the effective and suitable candidate to deliver a drug to the posterior segment of the eye with the highest biosafety and permeability.

Efficient wound treatments to target specific events in the healing process of chronic wounds constitute a significant aim in regenerative medicine. In this sense, nanomedicine can offer new opportunities to improve the effectiveness of existing wound therapies. The aim of this study was to develop catechol bearing polymeric nanoparticles (NPs) and to evaluate their potential in the field of wound healing. Thus, NPs wound healing promoting activities, potential for drug encapsulation and controlled release, and further incorporation in a hydrogel bioink formulation to fabricate cell-laden 3D scaffolds are studied. NPs with 2 and 29 M % catechol contents (named NP2 and NP29) were obtained by nanopptn. and presented hydrodynamic diameters of 100 and 75 nm resp. These nanocarriers encapsulated the hydrophobic compound coumarin-6 with 70% encapsulation efficiency values. In cell culture studies, the NPs had a protective effect in RAW 264.7 macrophages against oxidative stress damage induced by radical oxygen species (ROS). They also presented a regulatory effect on the inflammatory response of stimulated macrophages and promoted upregulation of the vascular endothelial growth factor (VEGF) in fibroblasts and endothelial cells. In particular, NP29 were used in a hydrogel bioink formulation using carboxymethyl chitosan and hyaluronic acid as polymeric matrixes. Using a reactive mixing bioprinting approach, NP-loaded hydrogel scaffolds with good structural integrity, shape fidelity and homogeneous NPs dispersion, were obtained. The in vitro catechol NPs release profile of the printed scaffolds revealed a sustained delivery. The bioprinted scaffolds supported viability and proliferation of encapsulated L929 fibroblasts over 14 days. We envision that the catechol functionalized NPs and resulting bioactive bioink presented in this work offer promising advantages for wound healing applications, as they: 1 support controlled release of bioactive catechol NPs to the wound site; 2 can incorporate addnl. therapeutic functions by co-encapsulating drugs; 3 can be printed into 3D scaffolds with tailored geometries based on patient requirements.

Bee venom-loaded EGFR-targeting peptide-coupled chitosan nanoparticles for effective therapy of hepatocellular carcinoma by inhibiting EGFR-mediated MEK/ERK pathway was written by Abdulmalek, Shaymaa;Mostafa, Nouf;Gomaa, Marwa;El-Kersh, Mohamed;Elkady, Ayman I.;Balbaa, Mahmoud.

Hepatocellular carcinoma (HCC) is one of the world′s most risky diseases due to the lack of clear and cost-effective therapeutic targets. Currently, the toxicity of conventional chemotherapeutic medications and the development of multidrug resistance is driving research into targeted therapies. The nano-biomedical field′s potential for developing an effective therapeutic nano-sized drug delivery system is viewed as a significant pharmaceutical trend for the encapsulation and release of numerous anticancer therapies. In this regard, current research is centered on the creation of biodegradable chitosan nanoparticles (CSNPs) for the selective and sustained release of bee venom into liver cancer cells. Furthermore, surface modification with polyethylene glycol (PEG) and GE11 peptide-conjugated bee venom-CSNPs allows for the targeting of EGFR-overexpressed liver cancer cells. A series of in vitro and in vivo cellular analyses were used to investigate the antitumor effects and mechanisms of targeted bee venom-CSNPs. Targeted bee venom-CSNPs, in particular, were found to have higher cytotoxicity against HepG2 cells than SMMC-7721 cells, as well as stronger cellular uptake and a substantial reduction in cell migration, leading to improved cancer suppression. It also promotes cancer cell death in EGFR overexpressed HepG2 cells by boosting reactive oxygen species, activating mitochondria-dependent pathways, inhibiting EGFR-stimulated MEK/ERK pathway, and elevating p38-MAPK in comparison to native bee venom. In hepatocellular carcinoma (HCC)-induced mice, it has anti-cancer properties against tumor tissue. It also improved liver function and architecture without causing any noticeable toxic side effects, as well as inhibiting tumor growth by activating the apoptotic pathway. The design of this cancer-targeted nanoparticle establishes GE11-bee venom-CSNPs as a potential chemotherapeutic treatment for EGFR over-expressed malignancies. Finally, our work elucidates the mol. mechanism underlying the anticancer selectivity of targeted bee venom-CSNPs and outlines therapeutic strategies to target liver cancer. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazoles in peptides or their ability to bind proteins, DNA and RNA has led to many synthetic studies and new applications. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Category: thiazole
