Synthesis and functionalization strategies of the imidazo[1,2-b]pyrazole core were developed giving a rapid access to three series of novel imidazo[1,2-b]pyrazole type derivatives: C-2/C-6/C-7 trisubstituted, C-2/C-3/C-6 tri(hetero)arylated and C-2/C-3/C-6/C-7 tetrasubstituted imidazo[1,2-b]pyrazoles. 39 of the synthetized products were evaluated for in vitro anticancer activity using the MTT colorimetric
开发了咪唑并[1,2- b ]吡唑核的合成和功能化策略,可快速获得三种新的咪唑并[1,2- b ]吡唑型衍生物:C-2 / C-6 / C-7三取代,C-2 / C-3 / C-6三(杂)芳基化和C-2 / C-3 / C-6 / C-7四取代的咪唑并[1,2- b ]吡唑。使用MTT比色测定法对39种合成产物的体外抗癌活性进行了评估,针对5种人类和1种鼠癌细胞系。一些目标化合物表现出有希望的体外生长抑制活性。39个评估产品,4所显示的IC 50 ≤10μM在6家细胞系分析(化合物4d中,4g,9a,11a)。还报道了结构活性关系分析。
