Abstract
The effect of the acyclic nucleotide analogue, 9-(2-phosphonomethoxyet hyl)adenine (PMEA, Adefovir), and its (bis)pivaloyloxymethyl ester (bi s-POM-PMEA, Adefovir Dipivoxil) on in vitro nitric oxide (NO) producti on by murine peritoneal macrophages was investigated. Bis-POM-PMEA inh ibited in a concentration-dependent manner the formation of NO generat ed by interferon-gamma and lipopolysaccharide, the IC50 being 15 mu M. Suppressed transcription of mRNA for inducible NO synthase (EC 1.14.1 3.39) resulting in decreased synthesis of NO synthase protein was foun d. Parent compound PMEA was virtually ineffective.
