A potent (IC50 = 30 nM), specific nonnucleoside HIV-1 reversetranscriptase (RT) inhibitor 3-[N-(phthalimidomethyl)amino]-5-ethyl-6-methylpyridin-2(1H) -one (1), was discovered through an in vitro screening program. This compound did not inhibit (IC50 > 300 microns) other DNA and RNA polymerases, including HIV-2 RT and SIV-RT. Unfortunately, hydrolytic instability of this (aminomethyl)phthalimide precluded
