在这项研究中,我们描述了新的降钙素原类似物,1 H-吡咯并[2,3- b ]吡啶衍生物的合成及其在弥漫性恶性腹膜间皮瘤(DMPM)(一种罕见且快速致命的疾病)的实验模型中的生物学作用对常规疗法有反应。三种活性最高的化合物1f(3- [2-(5-氟-1-甲基-1 H-吲哚-3-基)-1,3-噻唑-4-基] -1 H-吡咯并[2, 3- b ]吡啶),3f(3- [2-(1 H-吲哚-3-基)-1,3-噻唑-4-基] -1-甲基-1 H-吡咯并[2,3- b ]吡啶)和1l(3- [2-(5-氟-1-甲基-1 H-indol-3-yl)-1,3-thiazol-4-yl] -1-methyl-1 H -pyrrolo [2,3- b ]吡啶),它们被证明是细胞周期蛋白依赖性激酶1抑制剂,持续降低DMPM细胞增殖并诱导caspase依赖性凋亡反应,并同时降低抗凋亡蛋白survivin的活跃Thr
Synthesis and Antiproliferative Activity of Thiazolyl-bis-pyrrolo[2,3-b]pyridines and Indolyl-thiazolyl-pyrrolo[2,3-c]pyridines, Nortopsentin Analogues
indolyl-4-azaindolyl thiazoles, nortopsentin analogues, were conveniently synthesized. The antiproliferativeactivity of the new derivatives was examined against four human tumor cell lines with different histologic origin. Seven derivatives consistently reduced the growth of the experimental models independently of TP53 gene status and exhibited the highest activity against the malignant peritoneal mesothelioma
New thiazole nortopsentin analogs in which one of the two indole units was replaced by a naphthyl and/or 7-azaindolyl portion, were conveniently synthesized. Among these, three derivatives showed good antiproliferative activity, in particular against MCF7 cell line, with GI50 values in the micromolar range. Their cytotoxic effect on MCF7 cells was further investigated in order to elucidate their mode
