A series of benzo[b]furans was synthesized with modification at the 5‐position of the benzene ring by introducing C‐linked substituents (aryl, alkenyl, alkynyl, etc.). These compounds were evaluated for their antiproliferative activities, inhibition of tubulin polymerization, and cell‐cycle effects. Some compounds in this series displayed excellent activity in the nanomolar range against lung cancer
通过引入C连接的取代基(芳基,烯基,炔基等),在苯环的5位上进行修饰合成了一系列苯并[ b ]呋喃。对这些化合物的抗增殖活性,微管蛋白聚合抑制作用和细胞周期效应进行了评估。该系列中的某些化合物在纳摩尔范围内对肺癌(A549)和肾细胞癌(ACHN)癌细胞系表现出出色的活性。(6-甲氧基-5-((4-甲氧基苯基)乙炔基)-3-甲基苯并呋喃-2-基)(3,4,5-三甲氧基苯基)甲酮(26)和(E)-3-(6-甲氧基-3甲基-2-(1-(1,(3,4,5-三甲氧基苯基)乙烯基)苯并呋喃-5-基)丙-2-烯-1-醇(36)在A549细胞系中表现出显着活性,IC 50的0.08和0.06μ值中号分别。用这些化合物处理后,在A549细胞系中观察到G 2 / M细胞周期停滞和随后的凋亡。在该系列中最活跃的化合物36,具有类似于的考布他汀A-4(1.95和1.86μ的值也抑制微管蛋白聚合中号,分别地)。此外,详细的生物学研究(例如Hoechst
