摘要:
Novel cyclosporin analogs containing a MeAla or MeAbu residue at the 6-position of the cyclic undecapeptide have been synthesized and found unexpectedly to exhibit antagonistic activity toward cyclosporin A binding to its cytosolic protein receptor, cyclophilin, without being immunosuppressive.
摘要:
Hydroxymacrolides and derivatives of the general structural Formula I: ##STR1## have been prepared from suitable precursors by oxidation at C-20. These macrolides are useful as antagonists of FK-506-type immunosuppressants. The compounds of the present invention are useful for modifying dosages of FK-506-type immunosuppressants in the treatment of autoimmune diseases, infectious diseases and/or the prevention of rejection of foreign organ transplants. In addition, the compounds of the present invention have utility as antidotes for overdoses of FK-506-type immunosuppressants.
