The invention describes compositions and kits comprising at least one nitric oxide enhancing angiotensin II antagonist compound, or pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitric oxide enhancing angiotensin II antagonist compound, and, optionally, at least one nitric oxide enhancing compound and/or at least one therapeutic agent. The invention also provides methods for (a) treating cardiovascular diseases; (b) treating renovascular diseases; (c) treating diabetes; (d) treating diseases resulting from oxidative stress; (e) treating endothelial dysfunctions; (f) treating diseases caused by endothelial dysfunctions; (g) treating cirrhosis; (h) treating pre-eclampsia; (j) treating osteoporosis; (k) treating nephropathy; (l) treating peripheral vascular diseases; (m) treating portal hypertension (o) treating central nervous system disorders; (p) treating metabolic syndrome; and (q) treating hyperlipidemia. The nitric oxide enhancing angiotensin II antagonist compounds comprise at least one nitric oxide enhancing group linked to the angiotensin II antagonist compound through one or more sites such as carbon, oxygen and/or nitrogen via a bond or moiety that cannot be hydrolyzed.
Original loading and Suzuki conditions for the solid-phase synthesis of biphenyltetrazoles. Application to the first solid-phase synthesis of irbesartan
the heterocycle on a hydroxylated resin using zinc triflate. New Suzuki–Miyaura cross-coupling conditions are developed for the quantitative formation of the phenyl–phenyl bond. Our straightforward synthesis scheme, starting from the conserved phenyltetrazole moiety and ending with the appending of the structurally variable moiety, is well suited to the preparation of sartans and their analogues at
