In current work, a class of novel 4,5-dihydro-1H-pyrazole-1-carboxylate derivatives (E01-E28) were designed, synthesized and evaluated. Among them, the most potent compound E24 exhibited comparable activity against a panel of cancer cells (GI50 ranging 0.05–0.98 μM) and tubulin polymerization inhibition (IC50 = 1.49 μM) with reference drug CA-4(P) (GI50 ranging 0.019–0.32 μM, IC50 = 2.18 μM). The following
在当前工作中,设计,合成和评估了一类新型的4,5-二氢-1 H-吡唑-1-羧酸酯衍生物(E01-E28)。其中,最有效的化合物E24表现出相当的活性针对癌细胞的面板(GI 50测距0.05-0.98 μ M)和微管蛋白聚合的抑制(IC 50 = 1.49 μ M)参照药物CA-4(P)(GI 50测距0.019-0.32 μ男,IC 50 = 2.18 μ M)。以下测定表明化合物E24干扰了微管蛋白灾难性事件和抢救的动力学,从而触发了G2 / M阻滞,导致ROS积累,PARP裂解和细胞凋亡。分子动力学模拟验证了化合物E24可以紧密结合到微管蛋白异源二聚体与β的Lys 254和β在对接姿势微管蛋白的Cys的241。还确定了代谢稳定性和药代动力学参数。半衰期(t 1/2)显示了三个微粒体中的物种差异。血浆消除半衰期(t 1/2),血浆峰值浓度(C max),平均保留时间(MRT),曲线下面积(AUC0
