Candesartan is a selective AT1 (angiotensin II receptor 1) antagonist. Antagonism of angiotensin receptors inhibits vasoconstriction and the production of aldosterone, leading to a decrease in water and sodium concentration in blood plasma. Exhibits antihypertensive effects in animal models. Used in treatment of congestive heart failure, as antihypertensive. Candesartan does not affect cell viability or proliferation but increases the expression of VEGF and interleukin-8 in the cultured medium of KU-19-19 cells. Candesartan (0.1 nM) could reduce the maximal contractile response to angiostensin II by approximately 50%.
정의
ChEBI: A benzimidazolecarboxylic acid that is 1H-benzimidazole-7-carboxylic acid substituted by an ethoxy group at position 2 and a ({2'-(1H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl}methyl) group at position 1. It is a angiotensin
eceptor antagonist used for the treatment of hypertension.
일반 설명
Candesartan, (+)-1-[[(cyclohexyloxy)carbonyl]-oxy]ethyl 2- ethoxy-1-[[2'-(1H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl]methyl]-1H-benzimidazole-7-carboxylate(Atacand), like losartan, possesses the acidic tetrazole system,which most likely plays a role in binding to the angiotensin IIreceptor similarly to the acidic groups of angiotensin II. Also,the imidazole system has been replaced with a benzimidazolepossessing an ester at position. This ester must be hydrolyzedto the free acid. Fortunately, this conversion takesplace fairly easily because of the carbonate in the ester sidechain. This facilitates hydrolysis of the ester so much thatconversion to the free acid takes place during absorption fromthe gastrointestinal tract.
