The 2,2-disubstituted 2H-azirin-3-amines 7a-7c were used as amino acid synthons to prepare linear peptides derived from anthranilic acid. These linear peptides, which contain α,α-disubstituted α-amino acids, were synthesized by using the 'azirine/oxazolon

A number of N-benzoylglycines (6), N-acetyl-N-phenylglycines (7), N-benzoyl-N-phenylglycines (8), and tricyclic N-acetic acids (9-12) were synthesized as analogues of the N-acylglycine-containing aldolase reductase inhibitors alrestatin and 2-oxoquinoline-1-acetic acid.Derivatives of 6, which represent ring-simplified analogues of alrestatin, are very weak inhibitors of aldolase reductase obtained from rat lens, producing 50percent inhibition only at concentrations exceeding 100 μM.Compounds of series 7 were designed as ring-opened analogues of the 2-oxoquinolines.While this derivatives are more potent than compounds of series 6 (IC 50s of 6-80 μM), they are less active than the corresponding 2-oxoquinolines.Analogues of series 8 were designed as hybrid structures of both alrestatin and the 2-oxoquinoline-1-acetic acids.These compounds are substantially more potent than compounds of series 6 and 7 and display inhibitory activities comparable to or greater than alrestatin or the 2-oxoquinolines (IC 50s of 0.1-10 μM).Of the rigid analogues of 8, the most potent derivative is benzoxindol (12) with an IC 50 of 0.67 μM, suggesting that fusion of the two aromatic rings of 8 in a coplanar conformation may optimize affinity for aldose reductase in this series.
