ine (1), a histone acetyltransferase inhibitor previously identified by our research group and active at the sub‐millimolar/millimolar level, led to compounds bearing higher alkyl groups at the C2‐quinoline or additional side chains at the C6‐quinoline positions. Such compounds displayed at least threefold improved inhibitory potency toward p300 protein lysine acetyltransferase activity; some of them
对2-甲基-3-甲乙氧基喹啉(1)进行化学操作,这是我们研究小组先前确定的,在亚毫摩尔/毫摩尔水平上具有活性的组蛋白乙酰基转移酶抑制剂,导致化合物在C2-喹啉或其他基团上具有更高的烷基基团C6-喹啉位置的侧链。这类化合物对p300蛋白赖氨酸乙酰转移酶的抑制作用至少提高了三倍。其中一些降低了U937细胞的组蛋白H3和H4乙酰化水平,并诱导了U937细胞的高度凋亡(三种化合物比化合物1高10倍以上)。
