New organic dibasic acid half esters of 7-ketocholesterol and of 7-hydroxycholesterol represented by the general formula ##STR1## (wherein R.sub.1 is .dbd.O or --OH and R.sub.2 is a C.sub.1 -C.sub.5 alkylene group or a phenylene group) and physiologically acceptable salts thereof. These compounds are effective as an immunosuppressive or an anti-inflammatory agent.

Process for the preparation of cholesterol derivatives
