A series of pyridine acyl sulfonamide derivatives (1–24) have been designed and synthesized and their biological activities were also evaluated as potential cyclooxygenase-2 (COX-2) inhibitors. Among all the compounds, compound 23 displayed the most potent COX-2 inhibitory activity with an IC50 of 0.8 μM. Antitumor and anti-inflammatory assays indicated that compound 23 owned high antiproliferative
一系列吡啶酰基磺酰胺衍生物(的1 - 24)已经被设计和合成和它们的生物活性也进行了评价作为潜在的环氧合酶-2(COX-2)抑制剂。在所有化合物中,化合物23表现出最强的COX-2抑制活性,IC 50为0.8μM。抗肿瘤和抗炎实验表明,化合物23对B16-F10,HepG2和MCF-7癌细胞系具有很高的抗增殖活性,并且对鼠巨噬细胞RAW 264.7细胞具有COX-2衍生的前列腺素E 2(PGE 2)抑制活性。符合IC 50分别为2.8、1.2、1.8和0.15μM。进行对接模拟以将化合物23定位在COX-2活性位点中以确定可能的结合模型。
