  • Publication number: 20110262368
    Abstract: The present invention provides compounds of Formula (VII) and 11-keto analogs thereof, and pharmaceutically acceptable salts, solvates, esters, prodrugs, tautomers, and isomers of said compounds and said 11-keto analogs, having the general structure formula (VII): wherein L, R1, R2, R3, R4, and R5 are selected independently of each other and as defined herein. Also provided are pharmaceutical compositions, methods of preparing, and methods of using such compounds in the treatment and prophylaxis of a wide range of immune, autoimmune, and inflammatory diseases and conditions. The novel compounds of the present invention possess useful pharmacological activity while having unexpectedly low systemic activity. Thus, the compounds of the invention represent a safer alternative to those known glucocorticoids which have poor side-effect profiles.
