L-α-2′-Deoxythreosyl nucleoside phosphonates and their phosphonodiamidate prodrugs with a hypoxanthine, 2,6-diaminopurine, 2-amino-6-cyclopropylaminopurine, 7-deazaadenine, 5-fluorouracil and 5-methylcytosine heterocycle as a nucleobase were synthesized and evaluated for their inhibitory activity against HIV and HBV. The 2,6-diaminopurine modified analogue 23a displayed the most potent activity against
合成了以次黄嘌呤,2,6-二氨基嘌呤,2-氨基-6-环丙基氨基嘌呤,7-脱氮杂腺嘌呤,5-氟尿嘧啶和5-甲基胞嘧啶杂环为核碱基的L -α-2'-脱氧苏糖基核苷膦酸酯及其膦酰二氨基磺酸盐前药。评估其对HIV和HBV的抑制活性。的2,6-二氨基改性类似物23A显示抗HIV的最有效的活性,用EC 50 11.17μM的值抗HIV-1(III乙)和EC 50 8.15μM的抗HIV-2(ROD)值。前药策略在核苷膦酸酯23a上的应用导致抗HIV效能提高了200倍。在最高测试浓度下,没有一种化合物对乙肝病毒表现出任何活性。
