A series of benzothiazinone and benzooxazinone derivatives were discovered as SGLT2 inhibitors. The optimization led to the discovery of compounds 31 and 32, which exhibited similar potency and better SGLT1 selectivity compared to dapagliflozin. These compounds may provide novel promising scaffolds, which are different from phlorizin-based SGLT2 inhibitors. (C) 2011 Elsevier Ltd. All rights reserved.

Novel aminoalkyl triazoles are provided which are useful for the treatment of sensitized humans and animals for allergies and anaphylactic reactions. Additionally, a number of the compounds are useful in the treatment of hypertension. These compounds are of the formula ##STR1## wherein R.sub.4 is hydrogen, alkyl, alkoxy, aryl, sulfonyl, or sulfinyl, R.sub.5 is aryl, R.sub.6 is hydrogen, hydroxy, alkyl, alkoxy, or alkanoyloxy, and R.sub.1 is piperidinyl or amino.
Discovery of (5-(Benzylthio)-4-(3-(trifluoromethyl)phenyl)-4<i>H</i>-1,2,4-triazol-3-yl) Methanols as Potent Phytoene Desaturase Inhibitors through Virtual Screening and Structure Optimization
this work, we integrated structure-based virtual screening, structure-guided optimization, and biological evaluation to discover some PDS inhibitors with novel chemotypes. It is noteworthy that the highly potent compound 1b, 1-(4-chlorophenyl)-2-((5-(hydroxymethyl)-4-(3-(trifluoromethyl)phenyl)-4H-1,2,4-triazol-3-yl)thio)ethan-1-one, exhibited a broader spectrum of post-emergence herbicidal activity
八氢番茄红素去饱和酶(PDS)不仅是类胡萝卜素生物合成中的重要酶,也是发现除草剂的有希望的靶点。然而,近年来,尚未报道具有新支架的预期 PDS 抑制剂。因此,开发PDS抑制剂的解决方案是基于PDS蛋白结构寻找具有新化学型的新化合物。在这项工作中,我们整合了基于结构的虚拟筛选、结构引导优化和生物学评估,以发现一些具有新化学型的 PDS 抑制剂。值得注意的是,高效化合物1b 1-(4-氯苯基)-2-((5-(羟甲基)-4-(3-(三氟甲基)苯基)-4 H-1,2,4-triazol-3-yl)thio)ethan-1-one,与市售的 PDS 抑制剂 diflufenican 相比,在 375-750 g/ha 对六种杂草表现出更广谱的芽后除草活性。表面等离子共振 (SPR) 分析表明,我们的化合物1b ( K D = 65.9 μM) 对 PDS 的亲和力稍弱,但与二氟苯尼康 ( K D =
