A new series of pyrazole-naphthalene derivatives (5a-5q) have been synthesized and evaluated for their anticancer activity against human breast cancer cell lines (MCF-7). Most of newly synthesized compounds (except 5i, 5m, and 5p) exhibited potent antiproliferative activity in the range of IC50 = 2.78 ± 0.24 μM − 9.13 ± 0.47 μM. Among them, compound 5j (IC50 = 2.78 ± 0.24 μM), bearing ethoxy at the
合成了一系列新的吡唑-萘衍生物(5a - 5q),并评估了其对人乳腺癌细胞系(MCF-7)的抗癌活性。大多数新合成的化合物(5i,5m和5p除外)在IC 50 = 2.78±0.24μM-9.13±0.47μM的范围内表现出有效的抗增殖活性。其中, 发现在苯环的4位带有乙氧基的化合物5j(IC 50 = 2.78±0.24μM)是该系列化合物中活性最高的化合物,其活性是标准药物的五倍顺铂(IC 50 = 15.24±1.27μM)。另外,复合5j和秋水仙碱具有相同的抑制微管蛋白聚合的能力,IC 50值分别为4.6μM和6.7μM。细胞机制研究表明,化合物5j使细胞周期停滞在G2 / M期并诱导凋亡。此外,分子对接分析表明化合物5j在微管蛋白的秋水仙碱结合位点形成稳定的相互作用。
