nucleotides, in contrast to de novo biosynthesis that is utilized by the human host. A series of twenty-two 2-, 6- and 5'-modified adenosine ribonucleosides was synthesized, with the expectation that these compounds would generate toxic metabolites instead of active nucleotides by the pathogen, while remaining inert in host cells. Bioassays with P. falciparum (K1 strain) indicated IC50 values as low as 110nM
与人类宿主从头开始的生物合成相反,引起疟疾的寄生虫恶性疟原虫利用挽救途径进行核苷酸的生物合成。合成了22个2',6'和5'-修饰的腺苷核糖核苷,期望这些化合物能由病原体产生有毒的代谢产物而不是活性核苷酸,同时在宿主细胞中保持惰性。用恶性疟原虫(K1株)进行的生物测定表明,对于最有效的类似物,IC50值低至110nM,针对L6大鼠成肌细胞系的细胞毒性的选择性指数大于1000。
