title: Synthesis and angiotension converting enzyme inhibitory activity of L-lysyl-N-substituted glycine derivatives.
abstract: The synthesis and biological activity of novel L-lysyl-N-substituted glycine derivatives which exhibit in vitro and in vivo angiotensin converting enzyme (ACE) inhibition, are described. Particularly, N-[N alpha-(1-carboxy-3-phenylpropyl)-L-lysyl]-N-(4-phenylcyclohexyl)glycine (11e), N-[N alpha-(1-carboxy-3-cyclopentylpropyl)-N epsilon-carbobenzoxy-L- lysyl]-N-cyclopentyl glycine (9h) and N-[N alpha-[1(S)-carboxy-3-cyclohexylpropyl]-L-lysyl]-N-cyclopentyl glycine (19a) showed a strong inhibitory activity at IC50 as low as 0.65, 0.64 and 0.11 nmol/l, respectively. The most potent activity in vivo was observed with the compound 19a after i.v. administration in the rat.
