skeleton based 3-(halobenzyl)isocarbostyrils (2a–2i), were designed and synthesized to examine the effect of position of different halide substituents on anti-inflammatory activity. The structure–activity relationship shows a significant influence of position of halide substituents on in vitro anti-inflammatory activity. 3-(o-halobenzyl)isocarbostyrils (2a, 2d, and 2g) showed the lowest activity most probably
摘要设计并合成了一系列新的基于天然产物骨架的3-(卤代苄基)异羰基苯乙烯(2a – 2i),以研究不同卤化物取代基的位置对抗炎活性的影响。结构与活性的关系表明卤化物取代基的位置对体外抗炎活性具有重要影响。3-(邻卤代苄基)异咔唑(2a,2d和2g)表现出最低的活性,这很可能是由于卤化物与酰胺N–H之间的分子内氢键封闭了药效团的位置。相反,3-(对-卤代苄基)异咔唑2c,2f和2i表现出中等至非常好的炎症活性。发现化合物2c(IC 50 = 251.002±2.910)具有与标准药物(吲哚美辛,IC 50 = 271.210±2.127)相当的活性。为了进一步理解卤化物取代基的位置对3-(卤代苄基)异咔唑的影响,进行了计算POM。具有建设性命题的研究可能有助于设计更有效的类似物。 图形概要
