Ca. Bernhart et al., CYCLOPENTANESPIRO-3H-DIHYDRO-PYRIMIDINONES AS ANGIOTENSIN-II AT(1) RECEPTOR ANTAGONISTS, Bioorganic & medicinal chemistry letters, 4(1), 1994, pp. 157-162
A novel series of substituted H-3-dihydro-pyrimidinones, homologues of
SR 47436, was identified as AT(1) receptor antagonists. The best comp
ounds showed high affinity for the AT(1) receptor (rat liver membrane
preparation) with IC50's in the nanomolar range. Active p.o. in rats i
n an AII infused model, they are inactive in cynomolgus monkeys.
