摘要
9-(2-Phosphonylmethoxyethyl)adenine (PMEA; 1) was acylated with chloromethyl pivalate to afford bis(pivaloyloxymethyl) PMEA (2). The ester prodrug demonstrated enhanced in vitro potency against HSV-2 greater than 150-fold higher than the parent compound. The antiviral activity of 2 was 50-fold better than PMEA against HSV-1, and equipotent against HIV and HCMV. The toxicity of 2 was studied in both resting and growing cells.
