A series of novel N-substituted tyramine (2-p-hydroxyphenylethylamine) derivatives (1 to approximately 11) were synthesized and evaluated for their inhibitory activity against pig kidney aldose reductase (EC 1, 1, 1, 21). Of these compounds, N-2-p-hydroxyphenylethyl maleamic acid (10) exhibits the s
