Botryllazine B analogues of diverse substitution patterns have been prepared, and their in vitro inhibitory activities against recombinant human aldose reductase (h-ALR2) evaluated. Among the 15 compounds tested, 6-(4-aminophenyl)-2-(4-hydroxyphenyl)carbonylpyrazine (7b) proved to be the most potent inhibitor, with IC50=0.91 mu M. Kinetic analyses of 7b and botryllazine B(1) revealed that these inhibitors exhibit an unprecedented mixed-type inhibition on h-ALR2 with respect to the substrate D,L-glyceraldehyde, in the presence of NADPH at inhibitor concentrations near the IC50 values.
