Optically active or racemic compounds represented by the formula ##STR1## where R.sub.1 is C.sub.1 to C.sub.4 straight chain or branched alkyl; R.sub.2 is selected from the group consisting of H, --OR.sub.1, --SR.sub.1, --NH(R.sub.1), --N(R.sub.4)(R.sub.5), aminocarbonyl, halogen, and --CN, where R.sub.4 and R.sub.5 are independently C.sub.1 to C.sub.6 straight chain or branched alkyl, or taken together form a 3- to 7-membered heterocycloalkyl substituent, such heteroatom selected from the group consisting of oxygen, nitrogen and sulfur, optionally including an additional heteroatom which is selected from the group consisting of nitrogen, oxygen, and sulfur; R.sub.3 is cyclopentyl or: ##STR2## where R' and R' are independently H, .dbd.O, --OH, or --NH.sub.2, with the proviso that R' and R' can be taken together form the following structure as R.sub.3 : ##STR3## where R'' is --OH or --NH.sub.2 ; and with the further proviso that when R.sub.3 is cyclopentyl or norbornyl, then R.sub.2 cannot be H or halogen; and pharmaceutically-acceptable salts thereof. These compounds are useful as diuretics, renal protectives against acute or chronic renal failure, as well as agents to facilitate recovery from coma, to improve the therapeutic outcome resulting from defibrillation or cardiopulmonary resuscitation by preventing post-resuscitation bradycardia, bradyarrhythmia and cardioplegia, to restore cardiac function following a cardioplegic procedure, and to treat or prevent intermittent claudication.
