New Prodrugs of 9-(2-Phosphonomethoxyethyl)adenine [PMEA]: Synthesis and Stability Studies
摘要:
The synthesis, and stability in different media of new PMEA prodrugs, with S-acylthioethyl (SATE) as enzyme-labile phosphonate protecting groups, are described in comparison with the already known Bis(POM)- and Bis(DTE)PMEA.
Synthesis, <i>in Vitro</i> Antiviral Evaluation, and Stability Studies of Bis(<i>S</i>-acyl-2-thioethyl) Ester Derivatives of 9-[2-(Phosphonomethoxy)ethyl]adenine (PMEA) as Potential PMEA Prodrugs with Improved Oral Bioavailability
A new series of hitherto unknown 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA) phosphonodiester derivatives incorporating carboxyesterase-labile S-acyl-2-thioethyl (SATE) moieties as transient phosphonate-protecting groups was prepared in an attempt to increase the oral bioavailability of the antiviral agent PMEA. We report here a direct comparison of the in vitro anti-HIV and anti-HSV activities as
