Synthesis and biological activity of aldose reductase inhibitors with Michael acceptor substituents
摘要:
Derivatives of alrestatin (15) and alconil (6-8) possessing Michael acceptor substituents were synthesized as aldose reductase inhibitors. The alrestatin derivatives demonstrated enhanced aldose reductase inhibitory activity. The most potent reversible inhibitor of the series (compound 3) was 15-fold more active than alrestatin. Additionally, lipophilic analogues of alrestatin selectively inhibited rat lens aldose reductase versus rat kidney aldehyde reductase. Unlike alrestatin derivatives, alconil derivatives with similar substituents did not demonstrate significant reversible or irreversible inhibition of aldose reductase. (C) Elsevier, Paris.

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.
