ABSTRACT:
The synthesis of deuterated analogues of rapamycin is disclosed together with a method for use for inducing immunosupression and in the treatment of transplantation rejection, graft vs host disease, autoimmune diseases, diseases of inflammation leukemia/lymphoma, solid tumors, fungal infections, hyperproliferative vascular disorders. Also described is a method for the synthesis of water soluble deuteratred rapamycin compounds and their use as described above.
