  摘要：

  我们研究了N- [3,5-双（三氟甲基）苯基] [2-氯-4-（三氟甲基）嘧啶-5-基]羧酰胺（1）的结构-活性关系研究。 NF-kappaB和AP-1转录因子，旨在提高其潜在的口服生物利用度。检查化合物的基于细胞的活性，符合Lipinski的5法则，并使用肠上皮细胞系Caco-2检查潜在的胃肠道通透性。使用溶液相组合方法，将选定的基团在嘧啶环的2-，4-和5-位取代。用氟代替2-氯为1可以得到活性相当的化合物。然而，在2-位的其他取代导致活性丧失。在4-位的三氟甲基基团可以被甲基，乙基，氯或苯基取代，而没有实质性的活性损失。位于5位的羧酰胺基对于活性至关重要。如果将其移动到6位，则活动丢失。1的2-甲基类似物（81）与1相比显示出可比的体外活性并改善了Caco-2的渗透性。
