The present invention relates to compounds and compositions useful in modulating the renin-angiotensin system (RAS) in cells, and in particular to compounds which, inter alia, act as angiotensin II antagonists by binding to angiotensin II receptors. The invention also relates to the use of these compounds and compositions in the treatment of conditions responsive to angiotensin II antagonists such as hypertension, edema, renal failure, benign prostatic hypertrophy glaucoma, atherosclerosis, diabetes, Alzheimer's disease and congestive heart failure.
The present invention relates to a method of deprotecting a tetrazole compound, useful as an intermediate for angiotensin II receptor blockers, and provides a novel production method of angiotensin II receptor blockers.
Provided is a production method of a compound represented by the formula [3] or [4] or a salt thereof, including (i) reducing a compound represented by the formula [1] or [2] or a salt thereof in the presence of a metal catalyst and an alkaline earth metal salt, or (ii) reacting the compound with a particular amount of Brønsted acid:
wherein each symbol is as defined in the present specification.
Ubiquitin-like protein neddylation is overactivated in various human cancers and correlates with disease progression, and targeting this pathway represents a valuable therapeutic strategy. Our previous work disclosed an antihypertensive agent, candesartan cilexetic (CDC), serves as a novelneddylationinhibitor for suppressing tumor growth by targeting Nedd8-activating enzyme (NAE). In this study,
