Methods and novel intermediates for the preparation of and the treatment with acyclic nucleoside derivatives of the formula: where one of R1 and R2 is an amino acid acyl group and the other of R1 and R2 is a —C(O)C3-C21 saturated or monounsaturated, optionally substituted alkyl and R3 is OH or H.
摘要:
Compounds of the Formula I where one of R1 and R2 is —C(O)CH(CH(CH3)2)NH2 or —C(O)CH(CH(CH3)CH2CH3)NH2; the other of R1 and R2 is —C(═O)C3-C21 saturated or monounsaturated, optionally substituted alkyl; and R3 is OH or H; and pharmaceutically acceptable salts thereof have utility as enhanced bioavailability antivirals against herpes and retroviral infections.
