Pharmaceutically useful compounds of the following formula: ##STR1## wherein R.sub.1 represents hydrogen or hydroxy; R.sub.2 represents hydrogen; or R.sub.1 and R.sub.2 taken together form a second bond between the carbon atoms bearing R.sub.1 and R.sub.2 ; n is a positive whole integer of from 1 to 5; R.sub.3 is --CH.sub.3, --CH.sub.2 OH, --COOH or --COOalkyl wherein the alkyl moiety has from 1 to 6 carbon atoms and is straight or branched; and A and B are individually hydrogen or hydroxy; with the provisos that at least one of A or B is hydrogen and one of A or B is other than hydrogen when R.sub.3 is --CH.sub.3 ; and pharmaceutically acceptable acid addition salts thereof.
以下化学式的药用化合物:##STR1## 其中R.sub.1代表氢或羟基;R.sub.2代表氢;或者R.sub.1和R.sub.2一起形成承载R.sub.1和R.sub.2的碳原子之间的第二个键;n是从1到5的正整数;R.sub.3是--CH.sub.3,--CH.sub.2 OH,--COOH或--COOalkyl,其中烷基基团有1到6个碳原子,并且是直链或支链;A和B分别是氢或羟基;但至少A或B中的一个是氢,当R.sub.3是--CH.sub.3时,A或B中的一个不是氢;及其药用可接受的酸盐。
