    contain a functionalized ester group at 17 alpha has been prepared and examined to separate their systemic activity from topical antiinflammatory activity. Introduction of the functionalized ester group at 17 alpha was carried out by an acid-catalyzed formation of cyclic ortho esters with 17 alpha,21-hydroxyl groups of corticosteroids and subsequent acid-catalyzed hydrolysis. As for the functional group
    已经制备并检查了一系列在17α处含有官能化酯基的21-脱氧21-氯皮质类固醇,并将其全身活性与局部抗炎活性分开。通过酸催化形成具有皮质类固醇的17α,21-羟基的环状原酸酯,并随后进行酸催化的水解,来引入在17α的官能化酯基。至于官能团,在17个α-链烷酸酯基的末端碳原子上引入了氯,甲氧基,乙酰氧基,氰基,环丙基或烷氧羰基。检查了这些化合物的局部抗炎活性和全身活性,发现它们显着依赖于17种α-酯的功能。在这些衍生品中,一系列17种α-(烷氧基羰基)链烷酸酯(17α-OCO(CH2)nCOOR)表现出出色的全身活性与局部活性的分离。还研究了亚甲基数(n)和酯的烷基(R)对皮质类固醇衍生物的局部或全身活性的影响。
