Abstract

Tenofovir diphosphate (PMPApp) is a weak inhibitor of DNA polymerases (pol) alpha, delta, and epsilon*, with values for the Ki for PMPApp ((PMPApp)Ki) relative to the Km for dATP ((dATP)Km) of 10.2, 10.2, and 15.2, respectively. Its incorporation into DNA was about 1,000-fold less efficient than that of dATP, with (PMPApp)Km values 350-, 2,155-, and 187-fold higher than (dATP)Km values for pol alpha, delta, and epsilon*, respectively.
