Synthesis and Antiviral Evaluation of 1-O-Hexadecylpropanediol-3-P-acyclovir: Efficacy Against HSV-1 Infection in Mice
摘要:
We synthesized, 1-O-hexadecylpropanediol-3-P-acyclovir, an orally bioavailable lipid prodrug of acyclovir and evaluated it for in vitro and in vivo activity against herpes simplex virus infections. Although 1-O-hexadecylpropanediol-3-P-acyclovir was less active in vitro than acyclovir, on a molar basis it was 2.4 times more active orally in preventing mortality from acute HSV-I infection in mice. In vitro, 1-O-hexadecylpropanediol-3-P-acyclovir was also more active than acyclovir in a thymidine kinase negative mutant strain of HSV-1 (DM21) and had somewhat higher activity in cytomegalovirus infection in vitro due to it's ability to bypass thymidine kinase.

Several "sugar" modified acyclic nucleoside analogues related to 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, 2) were synthesized and evaluated for antiviralactivity. The preparation generally involved the condensation of the acetoxymethyl ether of alcohols 6c-g and 10-12a with diacetylguanine to give adducts 7c-g and 14-16, which were then deprotected to afford analogues 9c-g and 17-19.

at a time. In turn, macromolecular prodrugs (MP) are advantaged in carrying a high drug payload but offering only a modest extension of residence time to the conjugated drugs. In this work, we engineer MP to contain terminal groups that bind to albumin via non-covalent association and reveal that this facile measure affords a significant protraction for the associated polymers. This methodology is
