The possibility of deriving a potent, cell-penetrating inhibitor of humanerythrocyte 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

The synthesis of the C8-aryl adducts of adenine and guanine formed by reaction of the radical cation metabolites of carcinogenic polycyclic aromatic hydrocarbons (PAHs), such as benzo[a]pyrene (BP) and dibenzo[def,p]chrysene (DBC), with DNA is reported. The synthetic approach involves in the key step direct reaction of a PAH aldehyde with a di- or triamine precursor of a purine. The method is operationally
所述的合成Ç 8腺嘌呤和鸟嘌呤的芳基的加合物通过致癌的多环芳香烃(PAHs),如苯并[的自由基阳离子的代谢物的反应而形成一个]芘(BP)和二苯并[ DEF,p ]屈(chrysene)(DBC ),带有DNA的报道。合成方法的关键步骤是将PAH醛与嘌呤的二胺或三胺前体直接反应。该方法操作简单,提供良好的加合物收率,并且范围广泛。衍生自BP(6-BP-8-Ade和6-BP-8-Gua)和DBC(10-DBC-8-Ade和10-DBC-8-Gua)的腺嘌呤和鸟嘌呤的C 8芳基加合物为通过这种方法以高收率合成。类似的C 8其他多环芳烃(蒽,苯并[ a ]蒽和)的芳基腺嘌呤和鸟嘌呤衍生物也很容易通过这种方法制备。这种合成方法优于目前可用的唯一方法。它需要短寿命的PAH自由基阳离子(通过电化学或化学方法生成)与2'-脱氧核糖核苷或相应的嘌呤碱基直接反应。它以低收率提供加合物,并伴随有复杂的副产物混合
