A series of homologous C-nucleoside mimics have been synthesized via an efficient and facile synthetic protocol involving the conjugate addition of purine to sugar derived olefinic ester in good yields. The synthesized compounds were evaluated for their antiplasmodial activity in vitro against both the CQ-sensitive and resistant strains of P. falciparum. Interestingly, all the synthesized nucleoside
已经通过一种有效且容易的合成方案合成了一系列同源的C-核苷模拟物,所述合成方案涉及将嘌呤以良好的产率共轭加到糖衍生的烯烃酯中。评价了合成的化合物在体外对恶性疟原虫的CQ敏感和耐药菌株的抗疟原虫活性。有趣的是,所有合成的核苷类似物的IC 50值均小于5μM,而化合物22a,23a和23b的抗疟原虫活性良好,对CQ敏感的Pf的IC 50值为1.61、0.88和1.01μM。3D7菌株和针对CQ抗性Pf K1菌株的1.14、1.01和2.57μM。
