A series of indolo[2,3-a]pyrrolo[3,4-c]carbazoles and their bis-indolylmaleimides precursors have been prepared in order to compare their activity as D1-CDK4 inhibitors. Both enzymatic and antiproliferative assays have shown that the structurally more constrained indolo[2,3-a]pyrrolo[3,4-c]carbazoles are consistently more active (8-42-fold) in head-to-head comparison with their bis-indolylmaleimides
为了比较它们作为D1-CDK4抑制剂的活性,已经制备了一系列的吲哚[2,3-a]吡咯并[3,4-c]咔唑及其双-吲哚基马来酰亚胺前体。酶促和抗增殖试验均表明,结构上更受约束的吲哚[2,3-a]吡咯并[3,4-c]咔唑与它们的二甲苯胺相比,头对头的活性始终更高(8-42倍)。 -indolylmaleimides同行。使用流式细胞术的细胞周期分析还显示,吲哚并咔唑是选择性的G1阻滞剂,而双吲哚基马来酰亚胺则将细胞阻滞在G2 / M期。
