drugs acting against mitosis. These compounds, called microtubule targeting agents (MTAs), cause a mitotic arrest during G2/M phase, subsequently inducing cell apoptosis. MTAs could be classified in two groups: microtubule stabilising agents (MSAs) and microtubule destabilising agents (MDAs). In this paper we present a new series of (E) (Z)-2-(5,6-difluoro-(1H)2H-benzo[d] [1,2,3]triazol-1(2)-yl)-3-(R)acrylonitrile
微管 (MT) 是作用于有丝分裂的药物的主要目标。这些称为微管靶向剂 (MTA) 的化合物在 G2/M 期引起有丝分裂停滞,随后诱导细胞凋亡。MTA 可分为两类:微管稳定剂 (MSA) 和微管去稳定剂 (MDA)。在本文中,我们提出了一系列新的 ( E ) ( Z )-2-(5,6-difluoro-(1 H )2 H- benzo[ d ] [1,2,3]triazol-1(2)- yl)-3-( R )丙烯腈( 9a-j、10e、11a、b )和( E )-2-( 1H-苯并[ d)] [1,2,3]三唑-1-基)-3-(R)丙烯腈衍生物(13d,j),它们被认为是MTAs试剂。它们经过合理设计、合成、表征并进行了不同的生物学评估。进行计算对接以研究与微管蛋白上秋水仙碱结合位点的潜在结合。从这个第一个预测来看,二氟取代似乎有利于与微管蛋白的结合亲和力。与先前报道的化合物相比,这里介绍的
