We investigated the structure-activity relationship studies of N-[3, 5-bis(trifluoromethyl)phenyl][2-chloro-4-(trifluoromethyl)pyrimidin-5 -yl]carboxamide (1), an inhibitor of transcription mediated by both NF-kappaB and AP-1 transcription factors, with the goal of improving its potential oral bioavailability. Compounds were examined for cell-based activity, were fit to Lipinski's rule of 5, and were
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。
