The possibility of deriving a potent, cell-penetrating inhibitor of human erythrocyte PI 4-kinase, competitive with respect to ATP, has been investigated in a series of purine derivatives and analogues. The purine nucleus is not essential for binding to the ATP site but offers the advantage of synthetic accessibility to its derivatives. The optimum substitution pattern in purine was found to be an
在一系列嘌呤衍生物和类似物中,已经研究了获得有效的,可穿透细胞的人红细胞PI 4-激酶抑制剂(相对于ATP具有竞争性)的可能性。嘌呤核对于结合到ATP位点不是必不可少的,但具有合成易接近其衍生物的优势。发现嘌呤中的最佳取代方式是6-位的电子释放取代基(例如氨基,如腺嘌呤1),在8位或最好在9位是紧密的亲脂基团,表明N-1孤对的重要性以及8和9取代基对结合的疏水作用。合成的最有效的抑制剂是9-环己基腺嘌呤(54),其表观Ki值为3.7 microM。
