The clin. outcome of anti-HIV therapy is poor due to the inherent fallouts of anti-HIV therapy. It is further worsened due to the presence of viral reservoirs in immune cells like the macrophages. An ideal anti-HIV therapy must reach, deliver the drug and exert its action inside macrophages. To address this, we developed novel cationic nanostructured lipid carriers of efavirenz (cationic EFV-NLC). Th developed cationic EFV NLCs were evaluated for particle size, zeta potential, encapsulation effiency, in-vitro drug release, DSC, XRD, TEM, cytotoxicity, cellular uptake studies and anti-HIV efficy in a monocyte-derived macrophage cell line (THP-1). Cationic EFV-NLCs showed high encapsulation effiency (90.54 ± 1.7%), uniform particle size distribution (PDI 0.3-0.5 range) and high colloidal stability with pos. zeta potential (+23.86 ± 0.49 mV). DSC and XRD studies confirmed the encapsulation of EFV within NLCs. Cytotoxicity studies (MTT assay) revealed excellent cytocompatibility (CC50 13.23 ± 0.54 μg/mL). Fluorescence microscopy confirmed the effient uptake of cationic EFVNLCs, while flow cytometry revealed time and concentration dependant uptake within THP-1 cells. Cationic EFV-NLCs showed higher retention and sustained release with 2.32-fold higher percent inhibition of HIV-1 in infected macrophages as compared to EFV solution at equimolar concentrations Interestingly, they demonstrated 1.23-fold superior anti-HIV efficy over EFVloaded NLCs at equimolar concentrations Cationic NLCs were capable of inhibiting the viral replication at higher limits consistently for 6 days suggesting successful prevention of HIV-1 replication in infected macrophages and thus can prove to be an attractive tool for promising anti-HIV therapy. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Computed Properties of C20H18N2O2S).

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. 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.Computed Properties of C20H18N2O2S

Effect of carboxylic acid and cyanoacrylic acid as anchoring groups on Coumarin 6 dye for dye-sensitized solar cells: DFT and TD-DFT study was written by Saad Ebied, Mostafa;Dongol, Mahmoud;Ibrahim, Medhat;Nassary, Mohammed;Elnobi, Sahar;Abuelwafa, Amr Attia. And the article was included in Structural Chemistry.Related Products of 38215-36-0 The following contents are mentioned in the article:

Starting with Coumarin-6 dye, two novel D-π-A organic dyes C6X and C6N have been designed by attaching carboxylic acid and cyanoacrylic acid groups as anchoring groups to Coumarn-6 dye, resp., to understand their potential use in dye-sensitized solar cells (DSSCs). The electronic structure and photophys. and photovoltaic properties of the novel designed dyes were studied using d. functional theory DFT and time-dependent d. functional theory TD-DFT with the Becke3-Parameter-Lee-Yang-Parr (B3LYP) functional and the 6-31G (d, p) basis set. Optimized structure and electronic properties (HOMO energy (E_HOMO), LUMO (E_LUMO), and energy difference (E_g) between HOMO and LUMO) were calculated showing that C6N has the smallest band gap with the larger absorption region. D. of states (DOS), mol. electrostatic potential (MEP), natural bond orbital (NBO) anal., non-linear optical (NLO) properties, UV-vis spectra, as well as some crucial parameters affecting the photovoltaic performance of DSSCs, such as light-harvesting efficiency (LHE), electron injection driving force (ΔG^inject), dye regeneration driving force(ΔG^reg), and the excited state life time(τ_e), were calculated to study the effect of the anchoring group on the DSSC performance. Addnl., the adsorption of C6X and C6N dyes on the TiO₂ anatase (101) surface and the mechanism of electron injection were also investigated using a dye-(TiO₂)₉ cluster model using TD-B3LYP calculation The calculated adsorption energies of the dyes suggest a strong adsorption of dyes to a TiO₂ surface. The results show that C6N may be theor. a good candidate as sensitizer of DSSC application.

Coronavirus porcine epidemic diarrhea virus nucleocapsid protein interacts with p53 to induce cell cycle arrest in S-phase and promotes viral replication was written by Su, Mingjun;Shi, Da;Xing, Xiaoxu;Qi, Shanshan;Yang, Dan;Zhang, Jiyu;Han, Yuru;Zhu, Qinghe;Sun, Haibo;Wang, Xiaoran;Wu, Haoyang;Wang, Meijiao;Wei, Shan;Li, Chunqiu;Guo, Donghua;Feng, Li;Sun, Dongbo.

Subversion of the host cell cycle to facilitate viral replication is a common feature of coronavirus infections. Coronavirus nucleocapsid (N) protein can modulate the host cell cycle, but the mechanistic details remain largely unknown. Here, we investigated the effects of manipulation of porcine epidemic diarrhea virus (PEDV) N protein on the cell cycle and the influence on viral replication. Indicated that PEDV N induced Vero E6 cell cycle arrest at S-phase, which promoted viral replication (P < 0.05). S-phase arrest was dependent on the N protein nuclear localization signal S71NWHFYYLGTGPHADLRYRT90 and the interaction between N protein and p53. In the nucleus, the binding of N protein to p53 maintained consistently high-level expression of p53, which activated the p53-DREAM pathway. The key domain of the N protein interacting with p53 was revealed to be S171RGNSQNRGNNQGRGASQNRGGNN194 (NS171-N194), in which G183RG185 are core residues. NS171-N194 and G183RG185 were essential for N-induced S-phase arrest. Moreover, small mol. drugs targeting the NS171-N194 domain of the PEDV N protein were screened through mol. docking. Hyperoside could antagonize N protein-induced S-phase arrest by interfering with interaction between N protein and p53 and inhibit viral replication (P < 0.05). The above-described experiments were also validated in porcine intestinal cells, and data were in line with results in Vero E6 cells. Therefore, these results reveal the PEDV N protein interacts with p53 to activate the p53-DREAM pathway, and subsequently induces S-phase arrest to create a favorable environment for virus replication. These findings provide new insight into the PEDV-host interaction and the design of novel antiviral strategies against PEDV.

Glutathione-responsive copper-disulfiram nanoparticles for enhanced tumor chemotherapy was written by Chen, Meixu;Huang, Zeqian;Xia, Meng;Ding, Yaqing;Shan, Ting;Guan, Zilin;Dai, Xiuling;Xu, Xiaoyu;Huang, Yanjuan;Huang, Min;Zhao, Chunshun. And the article was included in Journal of Controlled Release in 2022.Reference of 38215-36-0 The following contents are mentioned in the article:

Disulfiram (DSF), a familiar FDA-approved drug used for alc. withdrawal, has recently been verified with potent antitumor therapeutic effect by generating Cu(DTC)₂, which is the complex of its metabolite diethyldithiocarbamate (DTC) and copper. However, its poor tumor selectivity and insufficient endogenous Cu²⁺ concentration within tumor site largely hinders the application of DSF-based antitumor therapy. Therefore, a GSH-responsive coordination nanoparticles (Cu-IXZ@DSF) was established as a copper carrier to achieve synchronous but sep. delivery of Cu²⁺ and DSF without antitumor ability, further to realize selectively triggered tumor in situ Cu(DTC)₂ generation for antitumor therapy. A widely-used proteasome inhibitor ixazomib (IXZ) was chosen as ligands and Cu²⁺ was used as coordination nodes to form nanosized Cu-IXZ@DSF. The DSF encapsulated in Cu-IXZ@DSF could be reduced to DTC by intracellular GSH, which could contend for Cu²⁺ and realize in situ high toxic Cu(DTC)₂ generation. Meanwhile, the chelation could lead to the disassembly of Cu-IXZ@DSF and release of IXZ to eventually achieve tumor specific “transformation from low toxicity to high toxicity” chemotherapy. The results of in vitro and in vivo experiments demonstrated that the as-prepared nanoplatform Cu-IXZ@DSF showed good biosafety and excellent antitumor effect via endoplasmic reticulum stress (ERS) as well as reactive oxygen species (ROS) generation pathway. Therefore, this nanocarrier provides an inspiring strategy with specific-triggered antitumor Cu(DTC)₂ generation for DSF-based chemotherapy with high therapeutic effect and biosafety and showing great potential of treating cancer.

Paracrine placental growth factor signaling in response to ionizing radiation is p53-dependent and contributes to radioresistance was written by Kazimova, Tamara;Tschanz, Fabienne;Sharma, Ashish;Telarovic, Irma;Wachtel, Marco;Pedot, Gloria;Schafer, Beat;Pruschy, Martin. And the article was included in Molecular Cancer Research in 2021.Reference of 63208-82-2 The following contents are mentioned in the article:

Placental growth factor (PlGF) is a pro-angiogenic, N-glycosylated growth factor, which is secreted under pathol. situations. Here, we investigated the regulation of PlGF in response to ionizing radiation (IR) and its role for tumor angiogenesis and radiosensitivity. Secretion and expression of PlGF was induced in multiple tumor cell lines (medulloblastoma, colon and lung adenocarcinoma) in response to irradiation in a dose- and time-dependent manner. Early upregulation of PlGF expression and secretion in response to irradiation was primarily observed in p53 wild-type tumor cells, whereas tumor cells with mutated p53 only showed a minimal or delayed response. Mechanistic investigations with genetic and pharmacol. targeting of p53 corroborated regulation of PlGF by the tumor suppressor p53 in response to irradiation under normoxic and hypoxic conditions, but with so far unresolved mechanisms relevant for its minimal and delayed expression in tumor cells with a p53-mutated genetic background. Probing a paracrine role of IR-induced PlGF secretion in vitro, migration of endothelial cells was specifically increased towards irradiated PlGF wild type but not towards irradiated PlGF-knockout (PIGF-ko) medulloblastoma cells. Tumors derived from these PlGF-ko cells displayed a reduced growth rate, but similar tumor vasculature formation as in their wild-type counterparts. Interestingly though, high-dose irradiation strongly reduced microvessel d. with a concomitant high rate of complete tumor regression only in the PlGF-ko tumors. Implications: Our study shows a strong paracrine vasculature-protective role of PlGF as part of a p53-regulated IR-induced resistance mechanism and suggest PlGF as a promising target for a combined treatment modality with RT.

Choline and PEG dually modified artemether nano delivery system targeting intra-erythrocytic Plasmodium and its pharmacodynamics in vivo was written by Wang, Ruili;Shi, Guangyu;Chai, Liqing;Wang, Rongrong;Zhang, Guoshun;Ren, Guolian;Zhang, Shuqiu. And the article was included in Drug Development and Industrial Pharmacy in 2021.Product Details of 38215-36-0 The following contents are mentioned in the article:

The choline derivative (CD) and polyethylene-glycol (PEG) dually modified artemether (ARM) nanostructured lipid carriers (CD-PEG-ARM-NLC) have been designed to prolong the circulation of ARM in blood, as well as to develop targeting for new permeability pathways (NPPs) and erythrocyte choline carriers (ECCs) that are expressed on the Plasmodium-infected erythrocyte membrane. The CD-PEG-ARM-NLC constructed in this study was found to be able to target endoerythrocytic Plasmodium by increasing the drug concentration and residence time in the infected erythrocytic microenvironment and minimizing toxicity and side effects. CD-PEG-ARM-NLC was prepared using high-pressure homogenization followed by physicochem. characterization. The targeting ability of CD-PEG-NLC to infected erythrocytes probed by coumarin-6 was investigated by using fluorescence microscopy imaging. The SYBR Green I assay for parasite nucleic acid was adapted in order to assess the efficacy of inhibition against parasite growth in vitro. The antimalarial activity of ARM-loaded NLCs was evaluated by a Pearson four-day suppressive test in Pyy265BY-bearing mice. In vitro imaging indicated that the intracellular delivery of CD-PEG-ARM-NLC was efficiently taken up by the infected erythrocytes via ECCs and NPPs, which could be inhibited by addition of furosemide (an inhibitor of NPPs) and excessive choline (native substrate of ECCs). Moreover, in vitro and in vivo studies that evaluated antimalarial activity suggested that CD-PEG-ARM-NLC exhibited higher antimalarial activity in comparison to ARM-NLC and PEG-ARM-NLC. These findings suggested that choline and PEG dually modified NLC could be promising preparations for the production of hydrophobic antimalarial drugs, particularly for ARM.

MicroRNA-377 acts as a suppressor in esophageal squamous cell carcinoma through CBX3-dependent P53/P21 pathway was written by He, Zhisheng;Chen, Junjing;Chen, Xiaoliang;Wang, Huanyuan;Tang, Lang;Han, Chunbin. And the article was included in Journal of Cellular Physiology in 2021.Safety of 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide The following contents are mentioned in the article:

Stem cells play pivotal roles in esophageal squamous cell carcinoma (ESCC) recurrence and metastasis. The self-renewal ability of stem cells was associated with specific microRNAs (miRs). Herein, we identified the effects of miR-377 on ESCC stem cell activities. First, the expression of miR-377 in ESCC and adjacent normal tissues was determined The relationship between miR-377 and chromobox protein homolog 3 (CBX3) was assessed by a dual-luciferase reporter gene assay. miR-377 was overexpressed or inhibited in ESCC stem cells to explore its role in ESCC. To further investigate the mechanism of miR-377 in ESCC, cells were introduced with short hairpin RNA against CBX3 or pifithrin-α (inhibitor of P53 pathway). Besides, the expression of P21, P53, CD133, CD13, Nanog, sex determining region Y-Box 2 (Sox2), and octamer-binding transcription factor 4 (Oct4), cell sphere formation, colony formation, and proliferation were evaluated resp. Finally, limiting dilution assay in vivo and tumor xenograft in nude mice were conducted to confirm the roles of miR-377 in vivo. miR-377 was poorly expressed in ESCC. Overexpression of miR-377 could suppress the stem-like trait of ESCC as well as the tumor growth in vivo. miR-377 targeted CBX3 to activate the P53/P21 pathway. Besides, the expression of stem-like markers including CD133, CD13, Oct4, Sox2, and Nanog was decreased, and the abilities of cell sphere formation, colony formation, proliferation, and tumorigenicity were significantly reduced by overexpressing miR-377 or silencing CBX3. The results were reversed after inactivating the P53/P21 pathway. In summary, upregulation of miR-377 inhibits the self-renewal of ESCC stem cells by inhibiting CBX3 expression and promoting activation of the P53/P21 pathway.

ER stress-induced modulation of neural activity and seizure susceptibility is impaired in a fragile X syndrome mouse model was written by Liu, Dai-Chi;Lee, Kwan Young;Lizarazo, Simon;Cook, Jessie K.;Tsai, Nien-Pei. And the article was included in Neurobiology of Disease in 2021.COA of Formula: C16H19BrN2OS The following contents are mentioned in the article:

Imbalanced neuronal excitability homeostasis is commonly observed in patients with fragile X syndrome (FXS) and the animal model of FXS, the Fmr1 KO. While alterations of neuronal intrinsic excitability and synaptic activity at the steady state in FXS have been suggested to contribute to such a deficit and ultimately the increased susceptibility to seizures in FXS, it remains largely unclear whether and how the homeostatic response of neuronal excitability following extrinsic challenges is disrupted in FXS. Our previous work has shown that the acute response following induction of endoplasmic reticulum (ER) stress can reduce neural activity and seizure susceptibility. Because many signaling pathways associated with ER stress response are mediated by Fmr1, we asked whether acute ER stress-induced reduction of neural activity and seizure susceptibility are altered in FXS. Our results first revealed that acute ER stress can trigger a protein synthesis-dependent prevention of neural network synchronization in vitro and a reduction of susceptibility to kainic acid-induced seizures in vivo in wild-type but not in Fmr1 KO mice. Mechanistically, we found that acute ER stress-induced activation of murine double minute-2 (Mdm2), ubiquitination of p53, and the subsequent transient protein synthesis are all impaired in Fmr1 KO neurons. Employing a p53 inhibitor, Pifithrin-α, to mimic p53 inactivation, we were able to blunt the increase in neural network synchronization and reduce the seizure susceptibility in Fmr1 KO mice following ER stress induction. In summary, our data revealed a novel cellular defect in Fmr1 KO mice and suggest that an impaired response to common extrinsic challenges may contribute to imbalanced neuronal excitability homeostasis in FXS.

Stabilization and Anticancer Enhancing Activity of the Peptide Nisin by Cyclodextrin-Based Nanosponges against Colon and Breast Cancer Cells was written by Khazaei Monfared, Yousef;Mahmoudian, Mohammad;Cecone, Claudio;Caldera, Fabrizio;Zakeri-Milani, Parvin;Matencio, Adrian;Trotta, Francesco. And the article was included in Polymers (Basel, Switzerland) in 2022.SDS of cas: 38215-36-0 The following contents are mentioned in the article:

The great variability of cancer types demands novel drugs with broad spectrum, this is the case of Nisin, a polycyclic antibacterial peptide that recently has been considered for prevention of cancer cells growth. As an accepted food additive, this drug would be very useful for intestinal cancers, but the peptide nature would make easier its degradation by digestion procedures. For that reason, the aim of present study to investigate the protective effect of two different β-cyclodextrin-based nanosponges (carbonyl diimidazole and pyromellitic dianhydride) and their anti-cancer enhancement effect of Nisin-Z encapsulated with against colon cancer cells (HT-29). To extend its possible use, a comparison with breast (MCF-7) cancer cell was carried out. The physicochem. properties, loading efficiency, and release kinetics of Nisin complex with nanosponges were studied. Then, tricin-SDS-PAGE electrophoresis was used to understand the effect of NSs on stability of Nisin-Z in the presence of gastric peptidase pepsin. In addition, the cytotoxicity and cell membrane damage of Nisin Z were evaluated by using the MTT and LDH assay, which was complemented via Annexin-V/ Propidium Iodide (PI) by using flowcytometry. CD-NS are able to complex Nisin-Z with an encapsulation efficiency around 90%. A protective effect of Nisin-Z complexed with CD-NSs was observed in presence of pepsin. An increase in the percentage of apoptotic cells was observed when the cancer cells were exposed to Nisin Z complexed with nanosponges. Interestingly, Nisin Z free and loaded on PMDA/CDI-NSs is more selectively toxic towards HT-29 cells than MCF-7 cancer cells. These results indicated that nanosponges might be good candidates to protect peptides and deliver drugs against intestinal cancers.

Strengthened rebamipide ocular nanoformulation to effectively treat corneal alkali burns in mice through the HMGB1 signaling pathway was written by Li, Qiqi;Wu, Xianggen;Xin, Meng. And the article was included in Experimental Eye Research in 2021.Recommanded Product: 38215-36-0 The following contents are mentioned in the article:

Corneal alkali burns are a major ophthalmic emergency, as current therapeutic treatments are limited. Novel treatment targets and new potential agents are required to combat this severe ocular injury. Glycyrrhizin and rebamipide (RBM) are both FDA-approved drugs with potential effects against corneal alkali burns, but RBM is limited by its low aqueous solubility and low bioavailability. This study aimed to utilize dipotassium glycyrrhizinate (DG, a dipotassium salt of glycyrrhizin) as a nanocarrier encapsulating RBM to formulate an ophthalmic solution (marked DG-RBM) with strengthened activities to treat corneal alkali burns. Results showed that an easy DG-RBM preparative process generated particles with high encapsulation efficacy and ultra-small micellar size. The solubility of RBM in DG-RBM in aqueous solution was 3.1 x 105-fold enhanced than its free solution DG-RBM exhibited excellent storage stability. In vitro cytotoxicity, ex vivo conjunctival responses, and rabbit eye tolerance tests showed that DG-RBM possessed good ocular safety profiles. DG-RBM exhibited improved in vivo corneal permeation profiles and demonstrated a strong effect against H2O2-induced oxidative damage, with a significant effect on promoting epithelial wound healing in corneal cells in vitro. As expected, in a mouse model of corneal alkali burns, the topical administration of DG-RBM achieved a strengthened efficacy against alkali burn damages. The mechanism of this therapeutic effect involved regulating high-mobility group box 1 (HMGB1) signaling and its related angiogenic and proinflammatory cytokines. These findings demonstrate the ease of preparing DG-RBM and its great potential as a novel ocular topical formulation to treat corneal alkali burns by regulating HMGB1 signaling.
