Nanocomposites of thiol-terminated liposomes encapsulating with coumarin-6 (CM6@Lip-SH) were successfully prepared via a simple thin-film dispersion method to construct a novel fluorescent sensor for selectively detecting trace amounts of patulin. Thiol group (-SH) was designed not only as a specific recognition element to capture patulin, but also as a convenient linker for the further separation of patulin-derivatized and un-derivatized CM6@Lip-SH by combination with magnetic NH₂-Au@Fe₃O₄ nanoparticles. Liposomes primarily provided an effective platform with a large surface area for facilitated accommodation of large amounts of recognition element (-SH group) and fluorophore (coumarin-6). In such an assay protocol, a reliable link was established between the changes in fluorescent intensity (ΔF) from the nanocomposites of CM6@Lip-SH/NH₂-Au@Fe₃O₄ and the concentrations of patulin in the range of 0.05-20 ng mL^-1, with the correlation coefficient of 0.996. This approach also effectively eliminated the background interference from other mycotoxins and metal ions. Under the optimal conditions, the designed sensor displayed excellent performance for patulin anal., with an extremely low detection limit (0.033 ng mL^-1), high recovery (96.2-107.6%) and excellent selectivity. Furthermore, the feasibility of its applications has also been demonstrated in the anal. of real juice samples, providing a novel tactics for rational design of a fluorescence assay, for point-of-care diagnostics of patulin, with great potential to be extended to other hazardous compounds by substitution of the recognition elements. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Recommanded Product: 38215-36-0).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Recommanded Product: 38215-36-0

Nanomedicine has attracted increasing attention and emerged as a safer and more effective modality in cancer treatment than conventional chemotherapy. In particular, the distinction of tumor microenvironment and normal tissues is often used in stimulus-responsive drug delivery systems for controlled release of therapeutic agents at target sites. In this study, we developed mesoporous silica nanoparticles (MSNs) coated with polyacrylic acid (PAA), and pH-sensitive lipid (PSL) for synergistic delivery and dual-pH-responsive sequential release of arsenic trioxide (ATO) and paclitaxel (PTX) (PL-PMSN-PTX/ATO). Tumor-targeting peptide F56 was used to modify MSNs, which conferred a target-specific delivery to cancer and endothelial cells under neoangiogenesis. PAA- and PSL-coated nanoparticles were characterized by TGA, TEM, FT-IR, and DLS. The drug-loaded nanoparticles displayed a dual-pH-responsive (pHe = 6.5, pHendo = 5.0) and sequential drug release profile. PTX within PSL was preferentially released at pH = 6.5, whereas ATO was mainly released at pH = 5.0. Drug-free carriers showed low cytotoxicity toward MCF-7 cells, but ATO and PTX co-delivered nanoparticles displayed a significant synergistic effect against MCF-7 cells, showing greater cell-cycle arrest in treated cells and more activation of apoptosis-related proteins than free drugs. Furthermore, the extracellular release of PTX caused an expansion of the interstitial space, allowing deeper penetration of the nanoparticles into the tumor mass through a tumor priming effect. As a result, FPL-PMSN-PTX/ATO exhibited improved in vivo circulation time, tumor-targeted delivery, and overall therapeutic efficacy. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Application In Synthesis of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).

Adhesion and release nanoparticle-mediated efficient inhibition of platelet activation disrupts endothelial barriers for enhanced drug delivery in tumors was written by Cao, Jinxu;Yang, Peng;Wang, Pengzhen;Xu, Shuting;Cheng, Yunlong;Qian, Kang;Xu, Minjun;Sheng, Dongyu;Li, Yixian;Wei, Yan;Zhang, Qizhi. And the article was included in Biomaterials in 2021.HPLC of Formula: 38215-36-0 The following contents are mentioned in the article:

Activated platelets can maintain tumor vessel integrity, thereby leading to limited tumor perfusion and suboptimal antitumor efficacy of nanoparticle-based drugs. Herein, to disrupt the tumor vascular endothelial barriers by inhibiting the transformation of resting platelets to activated platelets, a TM33 peptide-modified gelatin/oleic acid nanoparticle loaded with tanshinone IIA (TNA) was constructed (TM33-GON/TNA). TM33-GON/TNA could adhere to activated platelets by specifically binding their superficial P-selectin and release TNA into the extracellular space under matrix metalloproteinase-2 (MMP-2) stimulation, leading to local high TNA exposure. Thus, platelet activation, adhesion, and aggregation, which occur in the local environment around the activated platelets, were efficiently inhibited, leading to leaky tumor endothelial junctions. Accordingly, TM33-GON/TNA treatment resulted in a 3.2-, 4.0-, and 11.2-fold increase in tumor permeation of Evans blue (macromol. marker), small-sized Nab-PTX (∼10 nm), and large-sized DOX-Lip (∼100 nm), resp., without elevating drug delivery to normal tissues. Ultimately, TM33-GON/TNA plus Nab-PTX exhibited superior antitumor efficacy with minimal side effects in a murine pancreatic cancer model. In addition, the TM33-GON/TNA-induced disrupted endothelial junctions were reversibly restored after the treatment because the number of platelets was not reduced, which implies a low risk of the undesirable systemic bleeding. Hence, TM33-GON/TNA represents a clin. translational adjuvant therapy to magnify the antitumor efficacy of existing nanomedicines in pancreatic cancer and other tumors with tight endothelial lining. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0HPLC of Formula: 38215-36-0).

Fluorescence-Based and Fluorescent Label-Free Characterization of Polymer Nanoparticle Decorated T Cells was written by Thomsen, Tanja;Ayoub, Ahmed B.;Psaltis, Demetri;Klok, Harm-Anton. And the article was included in Biomacromolecules in 2021.Reference of 38215-36-0 The following contents are mentioned in the article:

Cells are attractive carriers for the transport and delivery of nanoparticulate cargo. The use of cell-based carriers allows one to enhance control over the biodistribution of drug-loaded polymers and polymer nanoparticles. One key element in the development of cell-based delivery systems is the loading of the cell-based carrier with the nanoparticle cargo, which can be achieved either by internalization of the payload or by immobilization on the cell surface. The surface modification of cells with nanoparticles or the internalization of nanoparticles by cells is usually monitored with fluorescence-based techniques, such as flow cytometry and confocal microscopy. In spite of the widespread use of these techniques, the use of fluorescent labels also poses some risks and has several drawbacks. Fluorescent dyes may bleach, or leach from, the nanoparticles or alter the physicochem. properties of nanoparticles and their interactions with and uptake by cells. Using poly(D,L-lactic acid) nanoparticles that are loaded with Coumarin 6, BODIPY 493/503, or DiO dyes as a model system, this paper demonstrates that the use of phys. entrapped fluorescent labels can lead to false neg. or erroneous results. The use of nanoparticles that contain covalently tethered fluorescent dyes instead was found to provide a robust approach to monitor cell surface conjugation reactions and to quant. analyze nanoparticle-decorated cells. Finally, it is shown that optical diffraction tomog. is an attractive, alternative technique for the characterization of nanoparticle-decorated cells, which obviates the need for fluorescent labels. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Reference of 38215-36-0).

Human induced pluripotent stem cell-derived platelets loaded with lapatinib effectively target HER2+ breast cancer metastasis to the brain was written by Bhan, Arunoday;Ansari, Khairul;Chen, Mike Y.;Jandial, Rahul. And the article was included in Scientific Reports in 2021.COA of Formula: C20H18N2O2S The following contents are mentioned in the article:

Prognosis of patients with HER2+ breast-to-brain-metastasis (BBM) is dismal even after current standard-of-care treatments, including surgical resection, whole-brain radiation, and systemic chemotherapy. Radiation and systemic chemotherapies can also induce cytotoxicity, leading to significant side effects. Studies indicate that donor-derived platelets can serve as immune-compatible drug carriers that interact with and deliver drugs to cancer cells with fewer side effects, making them a promising therapeutic option with enhanced antitumor activity. Moreover, human induced pluripotent stem cells (hiPSCs) provide a potentially renewable source of clin.-grade transfusable platelets that can be drug-loaded to complement the supply of donor-derived platelets. Here, we describe methods for ex vivo generation of megakaryocytes (MKs) and functional platelets from hiPSCs (hiPSC-platelets) in a scalable fashion. We then loaded hiPSC-platelets with lapatinib and infused them into BBM tumor-bearing NOD/SCID mouse models. Such treatment significantly increased intracellular lapatinib accumulation in BBMs in vivo, potentially via tumor cell-induced activation/aggregation. Lapatinib-loaded hiPSC-platelets exhibited normal morphol. and function and released lapatinib pH-dependently. Importantly, lapatinib delivery to BBM cells via hiPSC-platelets inhibited tumor growth and prolonged survival of tumor-bearing mice. Overall, use of lapatinib-loaded hiPSC-platelets effectively reduced adverse effects of free lapatinib and enhanced its therapeutic efficacy, suggesting that they represent a novel means to deliver chemotherapeutic drugs as treatment for BBM.

Neuroprotective effect of ultrasound triggered astaxanthin release nanoparticles on early brain injury after subarachnoid hemorrhage was written by Cai, Wei;Wu, Qi;Yan, Zhi Zhong;He, Wei-Zhen;Zhou, Xiao-Ming;Zhou, Long-Jiang;Zhang, Jian-Yong;Zhang, Xin. And the article was included in Frontiers in Chemistry (Lausanne, Switzerland) in 2021.Application of 38215-36-0 The following contents are mentioned in the article:

Subarachnoid hemorrhage (SAH) is a fatal disease. Within 72 h of SAH, the intracranial blood-brain barrier (BBB) is destroyed, and the nerve cells have responses such as autophagy, apoptosis, and oxidative stress. Antioxidation is an essential treatment of SAH. Astaxanthin (ATX) induces cells’ antioxidant behaviors by regulating related signal pathways to reduce the damage of brain oxidative stress, inflammation, and apoptosis. Because of its easy degradability and low bioavailability, ATX is mainly encapsulated with stimulus-responsive nanocarriers to improve its stability, making it rapidly release in the brain and efficiently enter the lesion tissue. In this study, the ultrasonic cavitation agent perfluorocarbon (PFH), ATX, and fluorescent dye IR780 were loaded with polydopamine (PDA) to prepare a US triggered release nanoparticles (AUT NPs). The coreshell structure of AUT NPs formed a phys. barrier to improve the bioavailability of ATX. AUT NPs have high ATX loading capacity and US responsiveness. The exptl. results show that the AUT NPs have high stability in the physiol. environment. Both US and pH stimuli can trigger the release. Under US, PFH breaks through the rigid shell. The structure of AUT NPs is destroyed in situ, releasing the loaded drugs into neuronal cells to realize the antioxidant and antiapoptotic effects. The in vivo experiment results show that the AUT NPs have good biosafety. They release the drugs in the brain under stimuli. The in vivo treatment results also show that AUT NPs have an excellent therapeutic effect. This approach presents an exptl. basis for the establishment of Innovative SAH treatments.

Nanoemulgel for Improved Topical Delivery of Desonide: Formulation Design and Characterization was written by Ma, Qiuyan;Zhang, Jing;Lu, Bohong;Lin, Huaqing;Sarkar, Rajib;Wu, Tao;Li, Xuee. And the article was included in AAPS PharmSciTech in 2021.Category: thiazole The following contents are mentioned in the article:

This research aimed to develop a novel drug delivery system to improve treatment of skin disorders. The system is comprised of a Carbopol 980-based nanoemulgel (NE-gel) containing a desonide (DES; 0.05%, weight/weight) nanoemulsion (NE), which has a small particle size, high encapsulation efficiency, good thermodn. stability, good permeation ability, and high skin retention. DES-loaded NE (DES-NE) was prepared by high-pressure homogenization. The developed formulation was characterized by differential scanning calorimetry (DSC), X-ray diffraction, drug release, skin permeation, and drug retention. DES in vitro release and skin permeation studies with different formulations of artificial membrane and rat abdominal skin were performed with the Franz diffusion cell system. Confocal laser scanning microscopy (CLSM) was used to detect the localization and permeation pathways of drugs in the skin. Compared with com. available gel (CA-gel) and NE, the NE-gel release process conformed to the Higuchi release model (R2 = 0.9813). NE-gel prolonged the drug release time and allowed for reduced administration dose and frequency. The unit cumulative permeation of NE and NE-gel through the skin for 12 h was 63.13 ± 2.78 and 42.53 ± 2.06μg/cm², resp., values significantly higher (p < 0.01) than that of the CA-gel (30.65 ± 1.25μg/cm²) and CA-cream (15.21 ± 0.97μg/cm²). The DES-NE and DES NE-gel skin drug retention was significantly higher than com. available formulations (p < 0.01). Hence, the prepared NE-gel is a potential vehicle for improved topical DES delivery for better treatment of skin disorders.

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current.Various laboratory methods exist for the organic synthesis of thiazoles. For example, 2,4-dimethylthiazole is synthesized from thioacetamide and chloroacetone.Category: thiazole

Multi-organ targeting of HIV-1 viral reservoirs with etravirine loaded nanostructured lipid carrier: An in-vivo proof of concept was written by Rojekar, Satish;Fotooh Abadi, Leila;Pai, Rohan;Mahajan, Ketan;Kulkarni, Smita;Vavia, Pradeep R.. And the article was included in European Journal of Pharmaceutical Sciences in 2021.Category: thiazole The following contents are mentioned in the article:

The inadequate bioavailability and toxicity potential of antiretroviral therapy limit their effectiveness in the complete eradication of HIV from viral reservoirs. The penetration of these drugs into the brain is challenging because of the unfavorable physicochem. properties required to cross the membranes, limiting the transport of the drugs. Thus, in the current study, the authors report a nanocarrier-based drug delivery of a highly hydrophobic drug to overcome the existing limitations of the conventional therapies. An explicitly simple approach was used to overcome the limitations of existing anti-HIV therapies. The monophasic hot homogenized solution of lipid, drug, and solubilizer was diluted with the predetermined hot surfactant solution followed by the ultrasonication to generate the polydisperse nanoparticles with the size range of 50-1000 nm. The anti-HIV1 potential of nanostructured lipid carriers of Etravirine on HIV-infected cell lines showed efficacy with an appreciable increase in the therapeutic index as compared with the plain drug. Further, the results obtained from confocal microscopy along with flow cytometry exhibited efficient uptake of the nanocarrier loaded with coumarin-6 in cells. The pharmacokinetics of Etravirine nanostructured carriers was significantly better in all aspects compared to the plain drug solution, which could be attributed to mol. dispersion in the lipid matrix of the nanocarrier. A significant enhancement of Etravirine concentration of several-fold was also observed in the liver, ovary, lymph node, and brain, resp., as compared to plain drug solution when assessed by biodistribution studies in rats. In conclusion, ETR-NLC systems could serve as a promising approach for simultaneous multi-site targeting and could provide therapeutic benefits for the efficient eradication of HIV/AIDS infections.

Effective chemotherapy for clin. treatment of brain diseases is still lacking due to the poor penetration of the blood-brain barrier (BBB). The aim of this study was to construct a folate modified pterostilbene (Pt) loaded polymeric micellar delivery system (F-Pt/M) with mPEG-PCL as carrier material to aim at penetrating the BBB for brain tissue targeting via receptor-mediated endocytosis. In this study, F-Pt/M was prepared using thin-film hydration method and then optimized by response surface methodol. (RSM) with the entrapment efficiency (EE), drug loading (DL) and hydrodynamic diameter (HD) as indexes. The average hydrodynamic diameter and ζ potential of optimal F-Pt/M were 133.2 nm and 24.6 mV, resp. DL (18.3%) and EE (98.6%) made the solubility of Pt in water about 25 times higher than that of crude Pt. Results of DSC evaluation revealed that drugs were successfully encapsulated inside the polymeric micelles. TEM images showed that homogeneous spherical micellar structures with a narrow size distribution were developed. The release result in vitro showed that F-Pt/M presented sustained release behavior compared to control free Pt solution Compared to non-targeted Pt/M, F-Pt/M had a significantly higher cytotoxicity against FR-overexpressing A172 cells. In vitro cellular uptake tests illustrated that the micellar delivery system could significantly improve the accumulation of drugs in target cells via receptor-mediated endocytosis. BBB penetration value (P) of F-Pt/M was about 4 folds higher than that of free Pt group. In addition, drug targeting index (DTI) was calculated to determine targeting of F-Pt/M to the brain which was found to be 4.89, implying improved brain targeting was achieved. Hence, the developed F-Pt/M exhibited great potential for delivering more drug mols. across the BBB for the treatment of brain diseases.

The purpose of this study was to develop astaxanthin (AST)-loaded self-microemulsifying drug delivery system (SMEDDS) tablets and evaluate their physicochem. and biol. properties. The optimized liquid (L)-AST SMEDDS formulation was composed of rice bran oil (33.67%), Kolliphor RH 40 (34.70%), and Span 20 (31.63%). Two types of hydrophilic polymers (hydroxypropyl methylcellulose, HPMC, and polyvinyl alc., PVA) solutions were selected as a precipitation inhibitor for AST and incorporated into L-AST SMEDDS to obtain supersaturation and enhance dissolution of AST. The formulation was then mixed with microcrystalline cellulose and subsequently transformed to solid S-AST SMEDDS particles using a spray dryer prior to direct compression into tablets. The HPMC AST SMEDDS tablet and PVA AST SMEDDS tablet were characterized for their physicochem. properties, dissolution, AST release, and stabilities. Moreover, the cellular uptake and antioxidant effect of AST SMEDDS tablets were evaluated in Caco-2 cells. With good tablet characters, both HPMC AST SMEDDS tablet and PVA AST SMEDDS tablet dissolution profiles were improved compared to that of raw AST. While initially less than 50% of AST released from HPMC AST SMEDDS tablet and PVA AST SMEDDS tablet in pH 1.2 medium, after 6 h more than 98% of AST releases in pH 6.8 were achieved which was similar to L-AST SMEDDS profile. Cellular antioxidant activities of L-AST SMEDDS and HPMC AST SMEDDS tablet & PVA AST SMEDDS tablet were significantly greater than pure AST powder. HPMC AST SMEDDS tablet showed better uptake and deeper penetration through Caco-2 cells than that in PVA AST SMEDDS tablet and pure powder. Our successfully developed AST SMEDDS tablets were demonstrated to be a potential platform to deliver highly lipophilic AST and improve permeation and bioavailability.
