FOXO1 mediates hypoxia-induced G0/G1 arrest in ovarian somatic granulosa cells by activating the TP53INP1-p53-CDKN1A pathway was written by Li, Chengyu;Liu, Zhaojun;Wu, Gang;Zang, Ziyu;Zhang, Jia-Qing;Li, Xiaoxuan;Tao, Jingli;Shen, Ming;Liu, Honglin. And the article was included in Development (Cambridge, United Kingdom) in 2021.SDS of cas: 63208-82-2 The following contents are mentioned in the article:

The development of ovarian follicles constitutes the foundation of female reproduction The proliferation of granulosa cells (GCs) is a basic process required to ensure normal follicular development. However, the mechanisms involved in controlling GC cell cycle are not fully understood. Here, by performing gene expression profiling in the domestic pig (Sus scrofa), we showed that cell cycle arrest at G0/G1 phase is highly correlated with pathways associated with hypoxic stress and FOXO signalling. Specifically, the elevated proportion of GCs at the arrested G0/G1 phase was accompanied by increased nuclear translocation of FOXO1 under conditions of hypoxia both in vivo and in vitro. Furthermore, phosphorylation of 14-3-3 by the JNK kinase is required for hypoxia-mediated FOXO1 activation and the resultant G0/G1 arrest. Notably, a FOXO1 mutant without DNA-binding activity failed to induce G0/G1 arrest of GCs during hypoxia. Importantly, we identified a new target gene of FOXO1, namely TP53INP1, which contributes to suppression of the G1-S cell cycle transition in response to hypoxia. Furthermore, we demonstrated that the inhibitory effect of the FOXO1-TP53INP1 axis on the GC cell cycle is mediated through a p53-CDKN1A-dependent mechanism. These findings could provide avenues for the clin. treatment of human infertility caused by impaired follicular development. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2SDS of cas: 63208-82-2).

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. 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.SDS of cas: 63208-82-2

Triptolide enhances lipolysis of adipocytes by enhancing ATGL transcription via upregulation of p53 was written by Wang, Xiaoyu;Xu, Meixue;Peng, Ying;Naren, Qimuge;Xu, Yanting;Wang, Xin;Yang, Gongshe;Shi, Xin’E.;Li, Xiao. And the article was included in Phytotherapy Research in 2020.Recommanded Product: 63208-82-2 The following contents are mentioned in the article:

Lipolysis is an essential physiol. activity of adipocytes. The Patatin Like Phospholipase Domain Containing 2 (PNPLA2) gene encodes the enzyme adipose triglyceride lipase (ATGL) responsible for triglyceride hydrolysis, the first step in lipolysis. In this study, we investigated the potential of triptolide (TP), a natural plant extract, to induce weight loss by examining its effect on ATGL expression. We found that long- and short-term TP administration reduced body weight and fat weight and increased heat production in brown adipose tissue in wild-type C57BL/6 mice. In 3T3-L1 fibroblasts and porcine adipocytes, TP treatment reduced the number of lipid droplets as determined by Oil Red O and BODIPY staining, with concomitant increases in free fatty acid and triglyceride levels in the culture medium. Combined treatment with TP and p53 inhibitor reversed these lipolytic effects. We next amplified the ATGL promoter region and identified conserved p53 binding sites in the sequence by in silico anal. The results of the dual-luciferase reporter assay using a construct containing the ATGL promoter harboring the p53 binding site showed that p53 induces ATGL promoter activity and consequently, ATGL transcription. These results demonstrate that TP has therapeutic value as an anti-obesity agent and acts by promoting lipolysis via upregulation of p53 and ATGL transcription. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Recommanded Product: 63208-82-2).

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) belongs to thiazole derivatives.

Coordination of rigidity modulation and targeting ligand modification on orally-delivered nanoparticles for the treatment of liver fibrosis was written by Yu, Yinglan;Xing, LiYun;Li, Lian;Wu, Jiawei;He, Jinhan;Huang, Yuan. And the article was included in Journal of Controlled Release in 2022.Category: thiazole The following contents are mentioned in the article:

Although the individual role of ligand modification or rigidity modulation on oral administration of nanoparticle (NP) has been investigated, how they mutually affect each other remains to be elucidated. Here, we fabricated different rigidity NP with or without surface decoration of FcBP, a neonatal Fc receptor domain-binding peptide. In vitro studies showed that, without FcBP modification, stiff NP had higher transcytosis efficiency across the epithelium than softer NP, due to the different endocytosis mechanisms, intracellular trafficking routes, and exocytosis rate. Notably, after FcBP modification, such difference was narrowed, in a manner that was more favorable for softer NP to “catch up” with stiff NP, suggesting ligand modification was more conducive to exert transcytosis-promoting efficacy on softer NP. In vivo experiments demonstrated that, for ligand-free NP, high rigidity was required for efficient oral absorption and liver distribution. Further FcBP modification decreased that “rigidity threshold”, and expanded the feasible rigidity range from stiff NP to softer NP. Upon oral administration, FcBP-modified dexamethasone-loaded softer NP achieved a therapeutic efficacy comparable with stiff NP on alleviating liver fibrosis. Collectively, our study highlighted the necessity of coordinating ligand modification and rigidity modulation for oral drug delivery. 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).

Fabrication of a pH-responsive core-shell nanosystem with a low-temperature photothermal therapy effect for treating bacterial biofilm infection was written by Peng, Dan;Liu, Genhua;He, Ye;Gao, Pengfei;Gou, Shuangquan;Wu, Jing;Yu, Jinxiu;Liu, Peng;Cai, Kaiyong. And the article was included in Biomaterials Science in 2021.Formula: C16H19BrN2OS The following contents are mentioned in the article:

Recently, photothermal therapy (PTT) has been recognized as a viable alternative strategy against bacterial biofilm infection. However, the hyperthermia required for PTT to ablate a biofilm usually induces damage in normal tissues/organs nearby. Herein, we developed zeolite-based imidazole framework (ZIF-8)-coated mesoporous polydopamine (MPDA) core-shell nanoparticles and then loaded Pifithrin-μ (PES), a natural inhibitor of heat-shock protein (HSP) that plays an essential role in bacteria resisting heating-induced damage. The ZIF-8 shell of the MPDA@ZIF-8/PES nanoplatform enabled a rapid degradation in response to the acidic environment in bacterial biofilm infection, which triggered the controlled release of PES and Zn ions. As a result, HSP was remarkably suppressed for enhancing PTT efficacy upon mild near-IR light irradiation In addition, the release of Zn²⁺ also had an antibacterial/antibiofilm effect. Thus, the fabricated nanosystem was able to induce the effective elimination of the bacterial biofilm, realizing low-temperature PTT (~45 °C) with excellent antibacterial efficacy. This work presented here not only provides a facile approach to fabricate the MPDA@ZIF-8/PES nanosystem with the responsiveness of the bacterial infection environment, but also proposes a promising low-temperature PTT strategy to treat bacterial biofilm-infection effectively.

Development of quercetin-loaded PVCL-PVA-PEG micelles and application in inhibiting tumor angiogenesis through the PI3K/Akt/VEGF pathway was written by Qi, Xueju;Gao, Cong;Yin, Chuanjin;Fan, Junting;Wu, Xiaochen;Di, Guohu;Wang, Jing;Guo, Chuanlong. And the article was included in Toxicology and Applied Pharmacology in 2022.Name: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Quercetin (Que) exhibits excellent biol. activity; however, its clin. development is hindered owing to the poor water solubility In this study, Que. was loaded on polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (PVCL-PVA-PEG, Soluplus) micelles through a thin-film hydration process, and their tumor angiogenesis inhibition ability was investigated. The particle size of Soluplus-Que micelles was 55.3 ± 1.8 nm, and the micelles stayed stability within 9 mo. Soluplus-Que micelles can enhance the cell uptake of Que. and transport the micelles to intracellular lysosomes and mitochondria. The MTT assay results revealed that Soluplus-Que micelles enhanced the cytotoxicity of Que. on HUVEC cells. Furthermore, Soluplus-Que micelles inhibited migration and invasion of HUVEC cells, as well as inhibited the neovascularization of chick embryo allantoic membrane (CAM). The in vivo study revealed that Soluplus-Que micelles significantly inhibit the growth of H22 solid tumors, with low toxic side effects. Soluplus-Que inhibited the expression of CD31 (a marker of angiogenesis) and the PI3K/Akt/VEGF pathway in tumor tissues, indicating its potential to hold back tumor growth via the inhibition of angiogenesis. Our findings indicated that as a delivery system, Soluplus micelles demonstrate potential for the delivery of poorly soluble drugs for tumor treatment.

The COX-2 inhibitor NS398 selectively sensitizes hypoxic HeLa cells to ionising radiation by mechanisms both dependent and independent of COX-2 was written by Anoopkumar-Dukie, Shailendra;Conere, Tom;Houston, Aileen;King, Liam;Christie, David;McDermott, Catherine;Allshire, Ashley. And the article was included in Prostaglandins and Other Lipid Mediators in 2020.Reference of 63208-82-2 The following contents are mentioned in the article:

It is widely accepted that the hypoxic nature of solid tumors contribute to their resistance to radiation therapy. There is increasing evidence that cyclooxygenase-2 (COX-2) contributes to increased resistance of tumors to radiation therapy. Furthermore, the mechanism by which these agents act remain largely unclear. Therefore, the aim of this study was to determine the impact of COX-2 selective inhibitors on both normoxic and hypoxic radiosensitivity in vitro and the mechanisms underlying this. Because of the close, reciprocal relationship between COX-2 and p53 we investigated their contribution to radioresistance. To achieve this we exposed HeLa, MCF-7 and MeWo cells to the COX-2 selective inhibitor, NS398 (10μM). NS398 (10μM) selectively sensitized hypoxic HeLa and MCF-7 but not MeWo cells to ionising radiation (5 Gy). We also show that ionising radiation at 5 Gy results in phosphorylation of p53 at serine 15, a key phosphorylation site for p53-mediated apoptosis, and that hypoxia attenuates this phosphorylation. Attenuated phosphorylation of p53 under hypoxic conditions may therefore contribute to hypoxic radioresistance. We also show that NS398 selectively phosphorylates p53 under hypoxic conditions following irradiation at 5 Gy. p53 phosphorylation could be an underlying mechanism by which this agent and other COX-2 inhibitors sensitize tumors to radiation therapy. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Reference of 63208-82-2).

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) 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.Reference of 63208-82-2

P53/PANK1/miR-107 signalling pathway spans the gap between metabolic reprogramming and insulin resistance induced by high-fat diet was written by Yang, Lu;Zhang, Bin;Wang, Xinju;Liu, Zhenhua;Li, Juan;Zhang, Shumiao;Gu, Xiaoming;Jia, Min;Guo, Haitao;Feng, Na;Fan, Rong;Xie, Manjiang;Pei, Jianming;Chen, Li. And the article was included in Journal of Cellular and Molecular Medicine in 2020.Related Products of 63208-82-2 The following contents are mentioned in the article:

High-fat diet (HFD) leads to obesity, type II diabetes mellitus (T2DM) and increases the coincidence of cardiovascular diseases and cancer. Insulin resistance (IR) is considered as the ‘common soil’ of those diseases. Furthermore, people on HFD showed restrained glycolysis and enhanced fatty acid oxidation, which is the so-called metabolic reprogramming. However, the relationship between metabolic reprogramming and IR induced by HFD is still unclear. Here, we demonstrate that PANK1 and miR-107 were up-regulated in the liver tissue of mice on HFD for 16 wk and involved in metabolic reprogramming induced by palmitate acid (PA) incubation. Importantly, miR-107 within an intron of PANK1 gene facilitated IR by targeting caveolin-1 in AML12 cells upon PA incubation. Moreover, we identify that HFD enhanced P53 expression, and activation of P53 with nutlin-3a induced PANK1 and miR-107 expression simultaneously in transcriptional level, leading to metabolic reprogramming and IR, resp. Consistently, inhibition of P53 with pifithrin-α hydrobromide ameliorated PA-induced metabolic reprogramming and IR. Thus, our results revealing a new mechanism by which P53 regulate metabolism In addition, the results distinguished the different roles of PANK1 and its intron miR-107 in metabolic regulation, which will provide more accurate intervention targets for the treatment of metabolic diseases.

JK184 can specially inhibit Gli in the Hedgehog (Hh) pathway, which showed great promise for cancer therapeutics. For developing aqueous formulation and improving anti-tumor activity of JK184, we prepared JK184 encapsulated MPEG-PCL micelles by the solid dispersion method without using surfactants or toxic organic solvents. The cytotoxicity and cellular uptake of JK184 micelles were both increased compared with the free drug. JK184 micelles induced more apoptosis and blocked proliferation of Panc-1 and BxPC-3 tumor cells. In addition, JK184 micelles exerted a sustained in vitro release behavior and had a stronger inhibitory effect on proliferation, migration and invasion of HUVECs than free JK184. Furthermore, JK184 micelles had stronger tumor growth inhibiting effects in s.c. Panc-1 and BxPC-3 tumor models. Histol. anal. showed that JK184 micelles improved anti-tumor activity by inducing more apoptosis, decreasing microvessel d. and reducing expression of CD31, Ki67, and VEGF in tumor tissues. JK184 micelles showed a stronger inhibition of Gli expression in Hh signaling, which played an important role in pancreatic carcinoma. Furthermore, circulation time of JK184 in blood was prolonged after entrapment in polymeric micelles.

Hepatocellular carcinoma (HCC) is one of the most common cancers. MicroRNA has been studied more and more deeply and may become a new target for the treatment of HCC. Here, we investigated the role of miR-455-3p in HCC progression. Compared with non-tumor tissues and normal human hepatic cells, miR-455-3p expression was significantly downregulated in HCC tissues and cell lines. And overexpression of miR-455-3p inhibited cell proliferation and migration but promoted cell apoptosis in HCC cell lines HepG2 and Huh7. Mechanism studies displayed that miR-455-3p targeted HDAC2 and neg. regulated HDAC2 expression. Moreover, HDAC2 was highly expressed in HCC tissues and cell lines. Overexpression of HDAC2 reversed the inhibitory effects of miR-455-3p on cell proliferation, migration and cell cycle protein (CDK6 and cyclin D1) expression, and neutralized the promotion effects of miR-455-3p on cell apoptosis and the activation of p53 pathway. Furthermore, a p53 inhibitor Pifithrin-α (PFT-α) effectively abolished the effects of miR-455-3p on HCC cell behaviors. Addnl., the role of miR-455-3p in tumorigenesis was evaluated by using a mouse xenograft model, and the data showed that miR-455-3p suppressed tumor growth in vivo. In summary, our results suggested that miR-455-3p targeted HDAC2 to inhibit cell proliferation, migration and promote cell apoptosis via the activation of p53 pathway.
