ABSTRACT:
A compound selected from the group consisting of a compound of the formula ##STR1## wherein R.sub.A, R'.sub.A, R.sub.B and R'.sub.B are individually selected from the group consisting of hydrogen and alkyl of 1 to 4 carbon atoms or R.sub.A and R'.sub.A or R.sub.B and R'.sub.B together with the nitrogen atom to which they are attached form a 5- to 6-member heterocycle optionally substituted with alkyl of 1 to 3 carbon atoms and Y is hydrogen or ##STR2## wherein R.sub.6 is selected from the group consisting of hydrogen, --CH.sub.3, --F and --Cl, R.sub.9 and R.sub.11 form a second bond at 9(11) or R.sub.9 is hydrogen or --F is hydrogen, --OH or .dbd.O, R.sub.16 is --CH.sub.3 or hydrogen, R.sub.17 is hydrogen, --OH or acyloxy, the dotted lines indicate the possible presence of a second bond at 1(2) and 6(7)-positions and the wavy line indicates the .alpha.- and .beta.-position and their non-toxic, pharmaceutically acceptable acid addition salts having anti-inflammatory and antioxidant activity.
