    • The present invention relates to compounds of formula (I), in which formula X is hydrogen or hydroxy or protected hydroxy; R1 an R2 stand for hydrogen, methyl or ethyl, or, when taken together with the carbon atom bearing the group X, R1 and R2 can form a C3-C5 carbocyclic ring; Q is a C3-C6 hydrocarbylene, hydrocarbylene indicating the diradical obtained after removal of 2 hydrogen atoms for a straight or banched, saturated or unsaturated hydrocarbon, in which one of any CH2 groups may optionally be replaced by an oxygen atom or a carbonyl group, such that the carbon atom (C-22) directly bonded to C-20 is an sp2 or sp3 hybridized carbon atom, i.e. bonded to 2 or 3 other atoms; and in which another of the CH2 groups may be replaced by phenylene, and where Q may optionally be substituted with one or more hydroxy or C1-C4-alkoxy groups. These compounds have been discovered to possess exceptionally high immunosuppressive activites together with high tumour cell proliferation inhibiting activities.
    • 本发明涉及式(I)化合物,其中式X为氢或羟基或被保护的羟基; R1,R2代表氢,甲基或乙基,或者当与带有基团X的碳原子一起时,R 1和R 2可以形成C 3 -C 5碳环; Q是C3-C6亚烃基,表示在去除2个氢原子之后获得的直链或带有饱和或不饱和烃的二价基团,其中任何一个CH 2基团可以任选被氧原子或羰基取代, 使得直接键合到C-20的碳原子(C-22)是sp2或sp3杂化的碳原子,即键合到2或3个其它原子; 并且其中另一个CH 2基团可以被亚苯取代,并且其中Q可以任选地被一个或多个羟基或C 1 -C 4 - 烷氧基取代。 已经发现这些化合物具有特别高的免疫抑制活性以及高肿瘤细胞增殖抑制活性。
