A. Ishii et al., HIGHLY SELECTIVE ALDOSE REDUCTASE INHIBITORS .1. 3-(ARYLALKYL)-2,4,5-TRIOXOIMIDAZOLIDINE-1-ACETIC ACIDS, Journal of medicinal chemistry, 39(9), 1996, pp. 1924-1927
A series of 3-(arylalkyl)-2,4,5-trioxoimidazolidine-1-acids (1) was pr
epared and tested for aldose reductase (AR) and aldehyde reductase (AL
R) inhibitory activities. These compounds showed strong inhibitory act
ivity against AR without significant inhibitory activity for ALR. The
ratio of IC50(ALR)/IC50(AR) was > 1000 in some compouds. On the basis
of pharmacological tests such as the recovery of reduced motor nerve c
onduction velocity and toxicological profile, 3-(3-nitrobenzyl)-2,4,5-
trioxoimidazolidine-1-acid (NZ-314) was selected as the candidate for
clinical development.
