The invention concerns a compound of the structure:
wherein Rl and R2 are each, independently, hydrogen, -CONH(CR3R4)n-X or CONHSO2-Ar; R3 and R4 are each independently, hydrogen, alkyl, aralkyl, cycloalkyl of 3-8 carbon atoms, halogen, or trifluoromethyl; providing that when more than one R3 or R4 group is present then they may be the same or different; X is hydrogen, lower alkyl, cycloalkyl, trifluoromethyl, nitro, alkoxy, carboalkoxy, aralkyl, halo, dialkylamino, thioalkyl, or Y; Y is a phenyl group which may be optionally mono-, di-, or tri- substituted; Ar is phenyl, naphthyl, pyridyl, quinolyl, isoquinolyl, quinoxalyl, thienyl, thionaphthyl, furyl, benzofuryl, benzodioxyl, benzoxazolyl, benzoisoxazolyl, or benzodioxolyl; wherein the Ar group may be optionally mono-, di-, or tri-subsrituted, and n = 0-5;
with the proviso that R1 and R2 are not both hydrogen and when n = 0, X is lower alkyl, cycloalkyl , aralkyl, or Y;
or a pharmaceutically acceptable salt thereof when X is dialkylamino, when the Ar group contains a basic nitrogen, or when the Ar group is substituted by dialklyamino, SO3H, -PO3H, or -CO2H, which by virtue of its immunosuppressive activity is useful in treating transplantation rejection, host vs. graft disease, autoimmune diseases and discases 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.
本发明涉及一种结构如下的化合物:
其中Rl和R2各自独立地为氢、-CONH(CR3R4)n-X或CONHSO2-Ar;R3和R4各自独立地为氢、烷基、芳烷基、3-8个碳原子的环烷基、卤素或三
氟甲基;当存在一个以上的R3或R4基团时,它们可以相同或不同;X为氢、低级烷基、环烷基、三
氟甲基、硝基、烷氧基、羧基、芳烷基、卤素、二烷基
氨基、
硫代烷基或Y;Ar 是苯基、

噻吩基、
硫萘基、
呋喃基、
苯并呋喃基、苯并二噁基、苯并
噁唑基、苯并
异噁唑基或苯并二
噁唑基;其中 Ar 基团可任选被单取代、二取代或三取代,且 n = 0-5;
但 R1 和 R2 不能都是氢,当 n = 0 时,X 为低级烷基、环烷基、芳烷基或 Y;
或其药学上可接受的盐,当 X 为二烷基
氨基时,当 Ar 基团含有碱基氮时,或当 Ar 基团被二烷基
