New 2-substituted benzoxazole derivatives were synthesized and screened for their in vitro anti-proliferative activities against MCF-7 and MDA-MB-231 cell lines. Compounds 4b, 4d and 11c eliciting the highest activity against MCF-7 cells were further assayed for their cytotoxic activities against A431 and HCC827 cancer cells in addition to their in vitro inhibition of wild and mutated epidermal growth
合成了新的2-取代的苯并恶唑衍生物,并筛选了它们对MCF-7和MDA-MB-231细胞系的体外抗增殖活性。除了体外抑制野生和突变的表皮生长因子受体(EGFR)酶外,进一步测定了对MCF-7细胞具有最高活性的化合物4b,4d和11c对A431和HCC827癌细胞的细胞毒性活性。化合物11c对A431细胞最有活性,它对EGFRWT表现出有效的抑制作用,而化合物4b和4d则比埃洛替尼对突变的EGFRL858R具有更高的效力。化合物4a,6c和8a对MDA-MB-231癌细胞表现出最强的细胞毒活性,其中化合物4a和6c的潜在芳香化酶(ARO)抑制剂比来曲唑稍弱。用化合物4b,4d,11c处理的MCF-7细胞和用化合物4a,6c和8a处理的MDA-MB-231细胞表现出caspase-9蛋白水平的显着过表达,并引起G1前细胞凋亡和细胞周期停滞在G2 / M期除高膜联蛋白V结合亲和力外,还表明细胞凋亡
