We have synthesised a series of 2-[[2-alkoxy-6-pentadecylphenyl)methyl]thio]-1H-benzimidazoles/benzothiazoles and benzoxazoles from anacardic acid and investigated their ability to inhibit human cyclooxygenase-2 enzyme (COX-2). The active compounds were screened for cyclooxygenase-1 (COX-1) inhibition. Compound 13 is 384-fold and 19 is more than 470-fold selective towards COX-2 compared to COX-1. Thus
我们已经从熊果酸中合成了一系列2-[[[2-烷氧基-6-十五烷基苯基]甲基]硫代] -1H-苯并咪唑/苯并噻唑和苯并恶唑,并研究了它们抑制人环加氧酶-2酶(COX-2)的能力。筛选活性化合物的环氧合酶-1(COX-1)抑制作用。与COX-1相比,化合物13对COX-2的选择性高384倍,而19的选择性高470倍。因此,这类化合物可作为选择性抑制COX-2的优良候选物。
