M.; de Looff, Wouter; Verveer, Peter C.; Kruse, Chris G. published 《Bioisosteric Replacements of the Pyrazole Moiety of Rimonabant: Synthesis, Biological Properties, and Molecular Modeling Investigations of Thiazoles, Triazoles, and Imidazoles as Potent and Selective CB1 Cannabinoid Receptor Antagonists》.Journal of Medicinal Chemistry published the findings.Category: esters-buliding-blocks The information in the text is summarized as follows:

Series of thiazoles, triazoles, and imidazoles were designed as bioisosteres, based on the 1,5-diarylpyrazole motif that is present in the potent CB1 receptor antagonist rimonabant. A number of target compounds were synthesized and evaluated in cannabinoid (hCB1 and hCB2) receptor assays. The thiazoles, triazoles, and imidazoles elicited in vitro CB1 antagonistic activities and in general exhibited considerable CB1 vs CB2 receptor subtype selectivities, thereby demonstrating to be cannabinoid bioisosteres of the original diarylpyrazole class. Some key representatives in the imidazole series showed potent pharmacol. in vivo activities after oral administration in both a CB agonist-induced hypotension model and a CB agonist-induced hypothermia model. Mol. modeling studies showed a close three-dimensional structural overlap between the imidazole I and rimonabant. A structure-activity relationship (SAR) study revealed a close correlation between the biol. results in the imidazole and pyrazole series.Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Category: esters-buliding-blocks) was used in this study.

The first-in-class soluble guanylate cyclase (sGC) stimulator riociguat was recently introduced as a novel treatment option for pulmonary hypertension. Despite its outstanding pharmacol. profile, application of riociguat in other cardiovascular indications is limited by its short half-life, necessitating a three times daily dosing regimen. In our efforts to further optimize the compound class, we have uncovered interesting structure-activity relationships and were able to decrease oxidative metabolism significantly. These studies resulting in the discovery of once daily sGC stimulator vericiguat (compound 24, BAY 1021189), currently in phase 3 trials for chronic heart failure, are now reported. In the experimental materials used by the author, we found Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Application of 16982-21-1)

The title of the article was 《Discovery of BMS-986339, a Pharmacologically Differentiated Farnesoid X Receptor Agonist for the Treatment of Nonalcoholic Steatohepatitis》.Formula: C4H7NO2S The author mentioned the following in the article:

While several farnesoid X receptor (FXR) agonists under clin. investigation for the treatment of nonalcoholic steatohepatitis (NASH) have shown beneficial effects, adverse effects such as pruritus and elevation of plasma lipids have limited their clin. efficacy and approvability. Herein, we report the discovery and preclin. evaluation of compound 32 (BMS-986339), a nonbile acid FXR agonist with a pharmacol. distinct profile relative to our previously reported agonist BMS-986318. Compound 32 exhibited potent in vitro and in vivo activation of FXR, albeit with a context-dependent profile that resulted in tissue-selective effects in vivo. To our knowledge, this is the first report that demonstrates differential induction of Fgf15 in the liver and ileum by FXR agonists in vivo. Compound 32 demonstrated robust antifibrotic efficacy despite reduced activation of certain genes in the liver, suggesting that the addnl. pharmacol. of BMS-986318 does not further benefit efficacy, possibly presenting an opportunity for reduced adverse effects. Further evaluation in humans is warranted to validate this hypothesis. In the part of experimental materials, we found many familiar compounds, such as Ethyl 2-amino-2-thioxoacetate(cas: 16982-21-1Formula: C4H7NO2S)

Inhibition of the programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) interaction by small-mol. inhibitors is emerging cancer immunotherapy. A series of novel 1,3,4-oxadiazole derivatives were designed, synthesized, and evaluated for their activities in vitro and vivo to find potent inhibitors of the PD-1/PD-L1 interaction. Among them, compound II-14 exhibited outstanding biochem. activity, with an IC50 of 0.0380 μM. Importantly, compound II-14, with a TGI value of 35.74 %, had more potent efficacy in a mouse tumor model compared to that in the control group. Surprisingly, when compound II-14 combined with 5-FU in a mouse tumor model having a TGI value of 64.59 %, which showed potential anti-tumor synergistic effects. Furthermore, immunohistochem. anal. demonstrated that compound II-14 activated the immune microenvironment by promoting the infiltration of CD4+ T cells into tumor tissues. These results indicate that compound II-14 is a promising lead compound for further development of small-mol. PD-1/PD-L1 inhibitors for cancer therapy.

The article was titled 《Discovery of 3,5-dimethylisoxazole derivatives as novel, potent inhibitors for bromodomain and extraterminal domain (BET) family》, and you may find the article in Bioorganic & Medicinal Chemistry.COA of Formula: C4H7NO2S The information in the text is summarized as follows:

Bromodomain and extra-terminal (BET) is a promising therapeutic target for various hematol. cancers. We used the BRD4 inhibitor compound 13 (I) as a lead compound to develop a variety of compounds, and we introduced diverse groups into the position of the compound 13 orienting toward the ZA channel. A series of compounds bearing triazolopyridazine motif exhibited remarkable BRD4 protein inhibitory activities. Among them, compound 39 (II) inhibited BRD4(BD1) protein with an IC50 of 0.003μM which was superior to lead compound 13. Meanwhile, compound 39 possess activity, IC50 = 2.1μM, in antiproliferation activity against U266 cancer cells. On the other hand, compound 39 could arrest tumor cells into the G0/G1 phase and induce apoptosis, which was consistent with its results in inhibiting cell proliferation. Biol. and biochem. data suggest that BRD4 protein might be a therapeutic target and that compound 39 is an excellent lead compound for further development.

Dysfunctional signaling through the phosphoinositide 3-kinase (PI3K)/AKT/mTOR pathway leads to uncontrolled tumor proliferation. In the course of the discovery of novel benzoxepin PI3K inhibitors, we observed a strong dependency of in vivo antitumor activity on the free-drug exposure. By lowering the intrinsic clearance, we derived a set of imidazobenzoxazepin compounds that showed improved unbound drug exposure and effectively suppressed growth of tumors in a mouse xenograft model at low drug dose levels. One of these compounds, GDC-0032 (I), was progressed to clin. trials and is currently under phase I evaluation as a potential treatment for human malignancies.

And the article was published in Bioorganic & Medicinal Chemistry Letters in 2019. COA of Formula: C4H7NO2S The author mentioned the following in the article:

The xanthine oxidase (XO) plays an important role in producing uric acid, and therefore XO inhibitors are considered as one of the promising therapies for hyperuricemia and gout. We have previously reported a series of XO inhibitors with pyrazole scaffold to extend the chem. space of current XO inhibitors. Herein, we describe further structural optimization to explore the optimal heterocycle by replacing the thiazole ring of Febuxostat with 5 heterocycle scaffolds unexplored in this field. All of these efforts resulted in the identification of compound 8, a potent XO inhibitor (IC50 = 48.6 nM) with novel 2-phenylthiazole-4-carboxylic acid scaffold. Moreover, lead compound 8 exhibited hypouricemic effect in potassium oxonate-hypoxanthine-induced hyperuricemic mice. These results promote the understanding of ligand-receptor interaction and might help to design more promising XO inhibitors.

Recommanded Product: Ethyl 2-amino-2-thioxoacetateIn 2017 ,《Utilization of an Active Site Mutant Receptor for the Identification of Potent and Selective Atypical 5-HT2C Receptor Agonists》 was published in Journal of Medicinal Chemistry. The article was written by Carpenter, Joseph; Wang, Ying; Wu, Gang; Feng, Jianxin; Ye, Xiang-Yang; Morales, Christian L.; Broekema, Matthias; Rossi, Karen A.; Miller, Keith J.; Murphy, Brian J.; Wu, Ginger; Malmstrom, Sarah E.; Azzara, Anthony V.; Sher, Philip M.; Fevig, John M.; Alt, Andrew; Bertekap, Robert L.; Cullen, Mary Jane; Harper, Timothy M.; Foster, Kimberly; Luk, Emily; Xiang, Qian; Grubb, Mary F.; Robl, Jeffrey A.; Wacker, Dean A.. The article contains the following contents:

Agonism of the 5-HT2C receptor represents one of the most well-studied and clin. proven mechanisms for pharmacol. weight reduction Selectivity over the closely related 5-HT2A and 5-HT2B receptors is critical as their activation has been shown to lead to undesirable side effects and major safety concerns. In this communication, we report the development of a new screening paradigm that utilizes an active site mutant D134A (D3.32) 5-HT2C receptor to identify atypical agonist structures. We addnl. report the discovery and optimization of a novel class of nonbasic heterocyclic amide agonists of 5-HT2C. SAR investigations around the screening hits provided a diverse set of potent agonists at 5-HT2C with high selectivity over the related 5-HT2A and 5-HT2B receptor subtypes. Further optimization through replacement of the amide with a variety of five- and six-membered heterocycles led to the identification of 6-(1-ethyl-3-(quinolin-8-yl)-1H-pyrazol-5-yl)pyridazin-3-amine (69). Oral administration of 69 to rats reduced food intake in an ad libitum feeding model, which could be completely reversed by a selective 5-HT2C antagonist.
