The invention concerns a compound of the structure
wherein R¹ and R² are each independently, hydrogen or
X is -(CH₂)m- or -Ar¹- ; R³ and R⁴ are each, independently, hydrogen, alkyl, -(CH₂)n-Ar, -(CH₂)p-NR⁵R⁶, or -(CH₂)p-N⁺R⁵R⁶R⁷Y⁻ ; R⁵ and R⁶ are each, independently, hydrogen, alkyl, or -(CH₂)n-Ar; Ar- and -Ar¹- are each optionally substituted mono- or bivalent radicals respectively of groups selected from
in which the optional substituents are selected from the group consisting of alkyl, aralkyl, alkoxy, cyano, halo, nitro, carbalkoxy, or perfluoroalkyl; R⁷ is alkyl; Y is a halide, sulfate, phosphate, or p-toluenesulfonate anion; m = 1 -6; n = 1-6; p = 1 -6; with the proviso that R¹ and R² are not both hydrogen; or a pharmaceutically acceptable salt thereof, which by virtue of its immunosuppressive activity is useful in treating transplantation rejection, host vs. graft disease, autoimmune diseases and diseases of inflammation; by virtue of its antitumor activity is useful in treating solid tumors; and by virtue of its antifungal activity is useful in treating fungal infections.
