Discovery of thiadiazole amides as potent, S1P3-sparing agonists of sphingosine-1-phosphate 1 (S1P1) receptor
摘要:
High-throughput screening of GSK compound collection led to the discovery of a novel series of thiadiazole amides as potent and S1P(3)-sparing sphingosine-1-phosphate 1 (S1P(1)) receptor agonists. Synthesis, structure and activity relationship, selectivity, and some developability properties are described. (C) 2012 Elsevier Ltd. All rights reserved.
小分子硫酯作为 SARS-CoV-2 主要蛋白酶抑制剂:酶抑制、构效关系、抗病毒活性和 X 射线结构测定
摘要:
SARS-CoV-2 的主要蛋白酶(M pro、 3CL pro)是冠状病毒中一个有吸引力的靶点,因为它在病毒复制和转录中发挥着至关重要的作用。在这里,我们报告了作为 SARS-CoV-2 M前抑制剂的新型小分子硫酯的设计、合成和构效关系。化合物3w和3x表现出优异的 SARS-CoV-2 M pro抑制作用,k inac / K i分别为 58,700 M –1 s –1 ( K i = 0.0141 μM) 和 27,200 M –1 s –1 ( K i = 0.0332 μM) , 分别。在 Calu-3 和 Vero76 细胞中,化合物3h、3i 、 3l、3r、3v、3w和3x显示纳摩尔范围内的抗病毒活性,且没有宿主细胞毒性。完成了3w和3af与 SARS-CoV-2 M pro的共结晶,X 射线结构显示与蛋白酶的催化 Cys145 残基共价结合。有效的 SARS-CoV-2 Mpro

Design, synthesis and biological evaluation of a series of 5-chloropyridine ester-derived severe acute respiratory syndrome-coronavirus chymotrypsin-like protease inhibitors is described. Position of the carboxylate functionality is critical to potency. Inhibitor 10 with a 5-chloropyridinyl ester at position 4 of the indole ring is the most potent inhibitor with a SARS-CoV 3CLpro IC(50) value of 30

The synthesis and structure-activity relationships (SAR) of p38 alpha MAP kinase inhibitors based on heterobicyclic scaffolds are described. This effort led to the identification of compound (21) as a potent inhibitor of p38a MAP kinase with good cellular potency toward the inhibition of TNF-alpha production. X-ray co-crystallography of an oxalamide analog (24) bound to unphosphorylated p38 alpha is also disclosed. (c) 2007 Elsevier Ltd. All rights reserved.
