Novel Renin Inhibitors Containing (2S,3S,5S)-2-Amino-1-cyclohexyl-6-methyl-3,5-heptanediol Fragment as a Transition-state Mimic at the P1-P1' Cleavage Site.
Novel Renin Inhibitors Containing (2S,3S,5S)-2-Amino-1-cyclohexyl-6-methyl-3,5-heptanediol Fragment as a Transition-state Mimic at the P1-P1' Cleavage Site.
The aldolreaction of optically active α-alkoxycarbonylamino aldehydes with a silylenolether in the presence of a Lewis acid afforded γ-amino-β-hydroxyketones diastereoselectively. The effect of the α-amide proton on the diastereoselectivity is discussed.
A series of low molecular renin inhibitors (molecular weight < 600) were prepared and their biological activities were evaluated. The inhibitors containing indole-2-carbonyl moieties at the P3 position and 2-amino-3,5-anti-diol fragment at the Pl-Pl' position showed renin inhibitory activities with IC50 of 10 (-8) M order and good blood pressure lowering effects after oral administration to sodium-depleted marmosets, (C) 1997 Elsevier Science Ltd.
