N-SUBSTITUTED IMIDAZOL-2-ONE COMPOUNDS FOR TREATMENT OF CIRCULATORY DISORDERS

摘要

A class of N-substituted imidazol-2-one compounds is described for use in treatment of circulatory disorders. Compounds of particular interest are angiotensin II antagonists of the formula wherein m is one; wherein R1 is selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, 4-methylbutyl, n-pentyl, neopentyl, phenyl, benzyl, phenethyl, cyclohexyl, cyclohexylmethyl, cyclohexylethyl, cyclohexanoyl, 1-oxo-2-cyclohexylethyl, benzoyl, 1-oxo-2-phenethyl, 1-oxopropyl, 1-oxobutyl, 1-oxopentyl and 2-hydroxybutyl; wherein R0 is selected from hydrido, methyl, fluoro, chloro, monofluoromethyl, difluoromethyl, trifluoromethyl, formyl, carboxyl and dimethoxymethyl; wherein R2 is selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, phenyl, benzyl, phenethyl, cyclohexyl, cyclohexylmethyl, propylthio, butylthio, and hydroxyalkyl; wherein each of R3, R4, R6, R7, R8, R10 and R11 is hydrido; with the proviso that at least one of R5 and R9 must be selected from COOH, SH, PO3H2, SO3H, CONHNH2, CONHNHSO2CF3, OH, wherein each of R42 and R43 is independently selected from chloro, cyano, nitro, trifluoromethyl, methoxycarbonyl and trifluoromethylsulfonyl; or a tautomer thereof or a pharmaceutically-acceptable salt thereof. These compounds are particularly useful in treatment or control of hypertension and congestive heart failure.
