K. Nakao et al., Benzoxazoline and benzimidazoline derivatives as novel aldose reductase inhibitors, part 2: Lead optimization, MED CHEM RE, 9(7-8), 1999, pp. 631-642
We designed novel aldose reductase inhibitors, benzoxazoline and benzimidaz
oline derivatives, bas ed on lead evolution from spiroquinazolinones. In or
der to optimize in vivo activity in the lens, variously substituted derivat
ives were synthesized. The relationship between structure and in vitro acti
vity was also analyzed by comparative molecular field analysis. The optimiz
ed compound exhibited high potency in the lens.
