[EN] The invention relates to a novel method for the preparation of imidapril hydrochloride of formula-l by reacting esters of 4(S)-1-methyl-2-oxoimidazolidine-4-carboxylate of formula-ll with (S)-ethyl-2-[(S)-4-methyl-2,5-dioxooxazolidin-3-yl]-4-phenylbutanoate of formula-Ill and hydrolyzing the coupled product with an alcoholic hydrochloride. [FR] La présente invention concerne un procédé innovant de préparation de chlorhydrate d'imidapril de formule (I). Selon ledit procédé, on fait réagir des esters de 4-carboxylate de 4(S)-1-méthyl-2-oxoimidazolidine de formule (II) avec du 4-phénylbutanoate de (S)-éthyl-2-[(S)-4-méthyl-2,5-dioxooxazolidin-3-yl] de formule (III) et on hydrolyse le produit couplé avec un chlorhydrate alcoolique.
Studies on angiotensin converting enzyme inhibitors. 4. Synthesis and angiotensin converting enzyme inhibitory activities of 3-acyl-1-alkyl-2-oxoimidazolidine-4-carboxylic acid derivatives
(4S)-1-Alkyl-3-[[N-(carboxyalkyl)amino]acyl]-2-oxoimidazolidine-4- carboxylic acid derivatives (3) were prepared by two methods. Their angiotensinconvertingenzyme (ACE) inhibitory activities and antihypertensive effects were evaluated, and the structure-activity relationships were discussed. The dicarboxylic acids 3a-n possessing S,S,S configuration showed potent in vitro ACE inhibitory activities
通过两种方法制备(4S)-1-烷基-3-[[[N-(羧烷基)氨基]酰基] -2-氧代咪唑烷-4-羧酸衍生物(3)。评估了它们对血管紧张素转化酶(ACE)的抑制活性和降压作用,并讨论了它们之间的构效关系。具有S,S,S构型的二元羧酸3a-n显示出有效的体外ACE抑制活性,IC50值为1.1 X 10(-8)-1.5 X 10(-9)M.在该系列中最有效的化合物是单酯3p,ID50值为0.24 mg / kg,在正常血压大鼠中抑制血管紧张素I诱导的升压反应,在剂量为1-10 mg / kg时自发性高血压大鼠(SHRs)的收缩压呈剂量依赖性降低。公斤,磅
