A series of N‐(4‐cyano‐3‐trifluoromethyl‐phenyl)‐2‐ethoxy‐6‐alkyl (and alkenyl) benzamides related to the anacardic acid derivative CTPB have been prepared from 2,6‐dihydroxybenzoic acid with a Suzuki coupling and addition of the anion of 4‐cyano‐3‐trifluoromethylphenylamine to a benzodioxinone as the key steps. In U937 cells, these analogues, in particular 7 c, 7 d, 7 f and 7 j, induced cell‐cycle
由2,6-二羟基苯甲酸与Suzuki偶联反应制得了一系列与被漆酸衍生物CTPB相关的N- (4-氰基-3-三氟甲基-苯基)-2-乙氧基-6-烷基(和烯基)苯甲酰胺关键步骤是将4-氰基-3-三氟甲基苯胺的阴离子添加到苯并二恶英中。在U937细胞中,这些类似物,特别是7 c,7 d,7 f和7 j,诱导了G1期的细胞周期停滞,导致约20%的细胞凋亡,并增加了H3的乙酰化水平。这些活动与组蛋白赖氨酸乙酰基转移酶(KAT):CBP和PCAF的酶促活化有关。
