The connection I receive the processing of (E)-3-[2-n-butyl-1-{(4-carboxyphenyl)methyl} -1-h-imidazol-5-yl] -2-(2-thienyl)methyl-2-propanolol acid methanesulfonic acid in 2-propanol at 8oC. 3 S. and 2 C.p. f-crystals.

The presented invention relates to new imidazolylalkyl acids, which are receptor antagonists angiotensin II and used in the regulation of arterial hypertension caused or aggravated by angiotensin II, and to treat congestive heart failure, renal failure, and glaucoma. This invention relates also to pharmaceutical compositions containing these compounds, and to methods of using these compounds as antagonists of angiotensin II as antihypertensive agents and agents for the treatment of congestive heart is a, known as angiotensin, due vazopressornye action underlying the etiology of arterial hypertension of the person. Inappropriate activity of renin-angiotensin systems is a key element in the being of hypertension, congestive heart failure and some forms of kidney disorders. In addition to the direct effect on arteries and arterioles, angiotensin AA (AII) is one of the well-known most potent endogenous vasoconstrictor agents, has a stimulating effect on the secretion of aldosterone from the adrenal cortex. Thus, the renin-angiotensin system, thanks to its participation in the management of renal sodium regulation plays an important role in cardiovascular homeostasis.

Violation of the renin-angiotensine system converting enzyme inhibitors such as captopril, is useful in the clinical treatment of hypertension and congestive heart failure (Abrams, W. B., and others, (1984), Federation Proc., 43, 1314). The most direct effect on the inhibition of the renin-angiotensine system should block the action of AII receptor. Undeniable evidence suggests that AII sposob serdeczna failure, cirrhosis and complication of pregnancy (Hollenberg, N. K. (1984), J. Cardiovas. Pharmacol., 6, S 176). In addition, recent studies in animals suggest that inhibition of the renin-angiotensine system can be successful in preventing or slowing the progression of chronic renal failure (Anderson. S. and others (1985), J. Clin. Invest., 76, 612). Also recently filed a Patent application (Patent application southern. Africa N 87/01, 653) argues that AII antagonists are useful as agents that can reduce and regulate elevated intraocular pressure, especially glaucoma, in mammals.

The compounds of this invention inhibit, block and counteract the action of the hormone AII and, therefore, are useful in regulating and mitigating caused by angiotensin hypertension, congestive heart failure, renal failure and other disorders caused by the action of AII. When the reception of the compounds of this invention animals raised blood pressure due to AII, decreases, and other manifestations, based on the action of AII, are minimized and regulated. It can be expected that the compounds of this invention exhibit diuretic is violence, related to the synthesis of antagonists of AII. The following links revealed imidazolone derivatives, which are characterized as having a blocking activity against AII and which are useful as antihypertensive agents.
