installation of phenolic hydroxyl group and extensive exploration of the P1 binding element led to the identification of 5-chloro-N-(5-chloro-2-pyridyl)-3-hydroxy-2-[4-(4-methyl-1,4-diazepan-1-yl)benzoyl]amino}benzamide (33, AS1468240) as a potent factor Xa inhibitor with significant oral anticoagulant activity. We also reported a newly developed Free-Wilson-like fragment recommender system based on the integration
Extending the Structure–Activity Relationship of Anthranilic Acid Derivatives As Farnesoid X Receptor Modulators: Development of a Highly Potent Partial Farnesoid X Receptor Agonist
The ligand activated transcription factor nuclear farnesoid X receptor (FXR) is involved as a regulator in many metabolic pathways including bile acid and glucose homeostasis. Therefore, pharmacological activation of FXR seems a valuable therapeutic approach for several conditions including metabolic diseases linked to insulin resistance, liver disorders such as primary biliary cirrhosis or nonalcoholic

identified as sustainable methine sources for synthesizing quinazolinone and benzimidazole derivatives using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone
首次将TsOH·H 2 O / O 2和适当的双亲核试剂组合使用,将醇和醚确定为可持续的次甲基来源,用于合成喹唑啉酮和苯并咪唑衍生物。氘标记研究清楚地证明了合成杂环的C 2氢来自次甲基。这些独特的反应条件已成功地用于合成棘金龙酮(2e'),2f'(rutaecarpine和(±)evodiamine的常见前体)和二咪唑(6d)。该方法的显着特征包括低毒性,使用商业原料作为底物,成本低,对官能团的耐受性强以及对多种双亲核起始原料的适用性。

screened for in vitro antimycobacterialactivity against Mycobacterium tuberculosis H37Rv, compound 3u (MIC: 4.20μM) was found to be most active and are superior over existing standard drugs ciprofloxacin and ethambutol. Compounds 3c and 3x were found to equally potent as ethambutol. Among most potent compounds in the series, four compounds (3n, 3o, 3p and 3u) showed lower cytotoxicity which could be promising
