Novel, non-steroidal anti-inflammatory drug (NSAID), acetaminophen conjugates 6a–l with amino acid linkers were synthesized utilizing benzotriazole chemistry. Biological data acquired for all the novel bis-conjugates showed (a) some bis-conjugates (6d, 6e, 6h, and 6k) exhibit more potent anti-inflammatory activity than their parent drugs, (b) the potent bis-conjugates show no visible stomach lesions
新型非甾体抗炎药(NSAID),具有氨基酸连接基的对乙酰氨基酚共轭物6a-1,是利用苯并三唑化学方法合成的。获得的所有新型双结合物的生物学数据表明(a)一些双结合物(6d,6e,6h和6k)比其母体药物显示出更强的抗炎活性,(b)强大的双结合物没有显示出与高度致溃疡的母体药物相比,可见的胃部病变明显;(c)有效的生物活性化合物在应用抗炎剂量的5倍时没有死亡率或毒性症状。具有统计学意义的QSAR模型,描述了6a–l的抗炎特性(使用验证所观察到的生物活性的CODESSA-Pro获得N= 15,n= 3,R 2= 0.891,R 2 cvOO = 0.770,R 2 cvMO = 0.796,F= 29.904,s 2= 0.011)。
