Guided by bioisosterism and pharmacokinetic parameters, we designed and synthesized a series of novel benzamide derivatives. Preliminary in vitro studies indicated that compounds 10b and 10j show significant inhibitory bioactivity in HepG2 cells (IC50 values of 0.12 and 0.13 μM, respectively). Compounds 10b and 10j induced the expression of HIF-1α protein and downstream target gene p21, and upregulated the expression of cleaved caspase-3 to promote tumor cells apoptosis.
在生物等排原理和药代动力学参数的指导下,我们设计并合成了一系列新型苯甲酰胺衍生物。初步体外研究表明,化合物10b和10j在HepG2细胞中显示出显著的抑制生物活性(IC50值分别为0.12和0.13 μM)。化合物10b和10j诱导了HIF-1α蛋白及其下游靶基因p21的表达,并上调了活化型caspase-3的表达,从而促进肿瘤细胞凋亡。
