In order to develop specific and sensitive immunoassays, new carboxylated derivatives of androstenedione, 11β-hydroxyandrostenedione, adrenosterone, progesterone, 17α-hydroxyprogesterone, corticosterone, 11-deoxycorticosterone and 21-deoxycortisol were synthesized. The preparation of the 4-carboxymethylthio and 4-carboxyethylthio derivatives of the Δ4-3-ketosteroids was carried out by base-catalyzed ring opening of the 4, 5-epoxides with mercaptoacetic acid and mercaptopropionic acid, respectively. The N-succinimidyl esters of these carboxylated steroids were also prepared.
为了开发特异性和灵敏度高的免疫检测,合成了类雄性激素、11β-羟基类雄性激素、肾上腺素、孕酮、17α-羟基孕酮、皮质酮、11-脱氧皮质酮和21-脱氧皮质醇的新型羧基衍生物。Δ4-3-酮类固醇的4-羧甲基硫和4-羧乙基硫衍生物的制备是通过在碱催化下,分别用巯基醋酸和巯基丙酸对4, 5-环氧化物进行开环反应来实现的。同时,也制备了这些羧基类固醇的N-琥珀酰亚胺酯。
