it as a safe cytotoxic agent. In addition, compound 11 displayed IC50 values of 63.44 μM and 98.60 μM against resistant HT-29 and resistant MCF-7 cancer cell lines sequentially. The most potent compound arrested cell cycle at G1/S phase in HT-29 treated cells displaying accumulation of cells in G0 phase and increase in percentage of cells in both early and late apoptotic stages. Apoptotic induction
设计、合成了新型不同取代的吡唑衍生物,并评估了它们的抗癌活性。所有化合物都选择性地抑制 COX-2 酶 (IC 50 = 0.043–0.56 μM)。化合物11、12和15显示出优异的效力 (IC 50 = 0.043–0.049 μM),并使用阿霉素和 5-FU 作为参考药物筛选了它们对 MCF-7 和 HT-29 癌细胞系的抗增殖作用。化合物11、12和15对 MCF-7 (IC 50 = 2.85–23.99 μM) 和 HT-29 (IC 50 = 2.12–69.37 μM) 细胞系表现出良好的效力。此外,还显示了化合物11、12和15(IC50 = 56.61–115.75 μM) 与多柔比星 (IC 50 = 13.32 μM) 相比,对非癌性 WI-38 细胞的作用。化合物11对 MCF-7 (IC 50 = 2.85) 和 HT-29 (IC 50 = 2
