Abstract
A class of N-substituted (.alpha.-imidazolyl-toluyl)pyrrole compounds described for use in treatment of circulatory disorders. Compounds of particular interest are angiotensin II antagonists of the formula ##STR1## wherein m is one; wherein each of R.sup.0 and R.sup.1 is independently selected from hydrido, alkyl, hydroxyalkyl, formyl, halo, haloalkyl, cycloalkylcarbonyl, alkoxy, aroyl, aryloxy, aralkoxy, alkylcarbonyl, alkoxycarbonyl, cyano, nitro, carboxyl, alkylcarbonyloxy, alkylcarbonyloxyalkyl, alkoxycarbonylalkyl, aralkoxycarbonylalkyl, alkylsulfonyl, aralkylsulfonyl, arylsulfonyl; wherein R.sup.2 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 R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9 and R.sup.10 is independently selected from hydrido, halo, nitro, trifluoromethyl, hydroxy, alkoxy, cyano, carboxyl and methoxycarbonyl; with the proviso that at least one of R.sup.5 and R.sup.8 must be selected from COOH, PO.sub.3 H.sub.2, SO.sub.3 H, CONHNH.sub.2, CONHNHSO.sub.2 CF.sub.3, ##STR2## wherein each of R.sup.42 and R.sup.43 is independently selected from chloro, cyano, nitro, trifluoromethyl, methoxycarbonyl and trifluoromethylsulfonyl; or a tautomer thereof or a pharmaceutically-aceptable salt thereof. These compounds are particularly useful in treatment or control of hypertension and congestive heart failure.
