The effect of the 3-carboxylic-ester variation in 2, 2-dimethyltrimethylene 3-alkoxycarbonyl-4-aryl-1, 4-dihydro-2, 6-dimethyl-5-pyridinephosphonates (1) was investigated with relation to the calcium-antagonistic and antihypertensive activities : the analogs contaning the alkyl groups of not more than 12 carbons and an amino functionality in the carboxylic-ester moiety were synthesized to be examined for biological activities. Among them, 2-[benzyl(phenyl)amino]-ethyl 5(5, 5-dimethyl-2-oxo-1, 3, 2-dioxaphosphorinan-2-yl)-1, 4-dihydro-2, 6-dimethyl-4-(3-nitrophenyl)-3-phridine-carboxylate hydrochloride ethanol (NZ-105) showed particularly beneficial activities and was selected for further pharmacological studies and clinical development. Some aspects of the structure-activity relationships and solid-state structure of NZ-105 by X-ray crystallographic analysis were described.
研究了3-羧酸酯变体在2,2-二甲基三甲基烯-3-烷氧羰基-4-芳基-1,4-二氢-2,6-二甲基-5-吡啶膦酸酯(1)中与钙拮抗和降压活性相关的影响:合成了含有不超过12个碳的烷基和羧酸酯部分含有氨基功能团的类似物,以检测其生物活性。其中,2-[苄基(苯基)氨基]乙基5-(5,5-二甲基-2-氧-1,3,2-二氧膦杂环己烷-2-基)-1,4-二氢-2,6-二甲基-4-(3-硝基苯基)-3-吡啶羧酸酯盐酸盐乙醇(NZ-105)显示出特别有益的活性,并被选中进行进一步的药理学研究和临床开发。描述了通过X射线晶体学分析获得的NZ-105的结构-活性关系和固态结构的一些方面。
