Structure-activity relationship of some steroidal compounds in ocular inflammation.
The structure-activity relationship of some topically applied 21-desoxy-substituted steroids as anti-inflammatory agents was investigated; the anti-inflammatory activity remained unaltered or increased on introducing a methyl group in position 6alpha and a hydroxyl group in position 11beta, even after eliminating the hydroxyl group in position 21. The activity of the molecule was further increased by the introduction of a hydroxyl group in position 17alpha and a fluorine atom in position 9alpha.
