ABSTRACT:
Inhibitors of nitric oxide formation from arginine useful for treating hypotension, inflammation, stroke and to restore vascular contractile sensitivity to the effects of .alpha..sub.1 adrenergic agonists are physiologically active compounds including N.sup..delta. -substituted ornithine or N.sup..epsilon. -substituted lysine moieties or monoalkyl carbon-substituted N.sup..delta. -substituted ornithine or N.sup..epsilon. -substituted lysine moieties, having the formula ##STR1## wherein R is (CH.sub.2).sub.y CH.sub.3 or H, R' is CH.sub.2 or C(H)(CH.sub.2).sub.y CH.sub.3, and R" is CH.sub.2 or C(H)(CH.sub.2).sub.y CH.sub.3, with y ranging from 0 to 5, and x is 0 or 1 and wherein none or only one of R, R' and R" provides an alkyl substituent on ornithine or lysine moiety, and wherein Q is a heme binding moiety and/or a sulfur-containing binding moiety and Q' is --NH.sub.2 when there is a double bond between the omega carbon and Q and Q' is .dbd.NH when there is a single bond between the omega carbon and Q, and physiologically acceptable acid addition salts thereof.
