A compound of the structure <IMAGE> II wherein R and R1 are each, independently, hydrogen, <IMAGE> <IMAGE> R2 and R3 are each, independently, hydrogen, alkyl, alkenyl, alkynyl, -CO2R5, -COR5, -CN, -NO2, -SO2R5, -SO3R5, -OR5, -SR5, or Ar; R4 is hydrogen, alkyl, alkenyl, alkynyl, -CF3, -NR5R6, -CO2R5, -COR5, CONR5, CONR5R6, -NO2, halogen, -OR5, -SR5, -CN, -SO2R5, -SO3R5, -SO2NR5R6, or Ar; R5 and R6 are each, independently, hydrogen, alkyl, alkenyl, alkynyl, or Ar; <IMAGE> are each, independently, a 5-7 membered saturated, unsaturated, or partially unsaturated heterocyclic radical, that is optionally fused to a phenyl ring or a cycloalkane or cycloalkene ring, wherein the heterocyclic ring may optionally contain O, S, or NR8 in the heterocyclic ring, and may be optionally substituted by R7; R7 is alkyl of 1-6 carbon atoms, alkenyl, alkynyl, -CF3, -NR5R6, -CO2R5, -COR5, CONR5R6, -NO2, halogen, -OR5, -SR5, -CN, -SO2R5, -SO3R5, -SO2NR5R6, or Ar; R8 is hydrogen, alkyl, alkenyl, alkynyl, -CF3, -NR5R6, -CO2R5, -COR5, CONR5R6, -OR5, -SR5, -CN, -SO2R5, -SO3R5, -SO2NR5R6, or Ar; Ar is phenyl, naphthyl, or hetaryl, wherein the foregoing may be optionally substituted; with the proviso that R and R1 are both not hydrogen, or a pharmaceutically acceptable salt thereof. which is useful as an immunosuppressive, antiinflammatory, antifungal, antiproliferative, and antitumor agent.
