A series of salicylic acid analogues of celecoxib where the phenylsulfonamide moiety in the structure of celecoxib is replaced by salicylic acid moiety was synthesized and tested for in vitro cyclooxygenase (COX)-1 and COX-2 enzyme inhibition. Among the series, 5-substituted-2-hydroxy-benzoic acid analogues (7a–7h) generally showed better inhibitory activities on both enzymes than 4-substituted-2-hydroxy-benzoic acid analogues (12a–12h). In particular, the chloro analogue 7f which had the highest inhibitory effect (IC50 = 0.0057 µM) to COX-1 with excellent COX-1 selectivity (SI = 768) can be classified as a new potent and selective COX-1 inhibitor. The high inhibitory potency of 7f was rationalized through the docking simulation of this analogue in the active site of COX-1 enzyme.
一系列塞来昔布的水杨酸类似物被合成并测试了它们对体外环氧合酶(COX)-1和COX-2酶的抑制作用,这些类似物在结构上用水杨酸部分替代了塞来昔布的苯磺酰胺部分。在这一系列化合物中,5-取代-2-羟基苯甲酸类似物(7a–7h)通常比4-取代-2-羟基苯甲酸类似物(12a–12h)对这两种酶显示出更好的抑制活性。特别是氯代类似物7f,它对COX-1的抑制效果最高(IC50 = 0.0057 µM),并具有极佳的COX-1选择性(SI = 768),可被归类为一种新型强效且选择性的COX-1抑制剂。7f的高抑制效力通过将该类似物对接模拟到COX-1酶的活性位点得到了合理解释。
