A series of COX-2 selective inhibitor nimesulide derivatives were synthesized. Their anti-cell proliferation activities were evaluated with a long-term estrogen deprived MCF-7aro (LTEDaro) breast cancer cell line, which is the biological model of aromatase inhibitor resistance for hormone-dependent breast cancer. Compared to nimesulide which inhibited LTEDaro cell proliferation with an IC(50) at 170.30 microM, several new compounds showed IC(50) close to 1.0 microM.
合成了一系列 COX-2 选择性抑制剂尼美舒利衍生物。用长期去雌激素 MCF-7aro(LTEDaro)乳腺癌细胞系评估它们的抗细胞增殖活性,该细胞系是激素依赖性乳腺癌芳香酶抑制剂耐药的生物学模型。与尼美舒利的 IC(50)为 170.30μM 抑制 LTEDaro 细胞增殖相比,几种新化合物的 IC(50)接近 1.0μM。
