title: Synthesis and biological evaluation of irreversible inhibitors of aldose reductase.
abstract: 5-Isothiocyanatoalrestatin (1b) and 5-azidoalrestatin (1c) were prepared synthetically and examined as potential affinity and photoaffinity inhibitors of rat lens aldose reductase. Both compound 1b and 1c under appropriate conditions at 10(-4) M produced a 70% irreversible inactivation of aldose reductase within 1 min. The enzyme could, in part, be protected by preincubation with sorbinil 2, a known potent inhibitor of aldose reductase.
