Compounds according to formula I: in which formula R1 and R2, which may be the same or different, represent halogen, (C1-C6) hydrocarbyl, optionally substituted with one or two hydroxyl group on one or more fluorine atoms, or, together with the carbon atom to which they are both attached, R1 and R2 form a (C3-C6)carbocyclic ring, or one of R1 and R2 taken together with R3 forms a direct bond, such that a triple bond is constituted, or R1 and R2 represent both hydrogen; R3 when not forming a direct bond with one of R1 and R2 represents hydrogen or (C1-C3)hydrocarbyl; X represents (E)-ethylene, (Z)-ethylene, ethynylene, or a bond; Y and Z independently represent hydrogen or methyl; the bond between C#16 and C#17 is depicted with a dotted line to illustrate that said bond may be either a single bond, in which case the projection of the ring substituents is beta, or a double bond; A represents hydroxyl, fluorine or hydrogen; B represents CH2 or H2; the configuration is the 3-position corresponds to the same configuration as in natural vitamine D3 (normal), or the configuration in the configuration in the 3-position is opposite to that of natural vitamin D3(epi); with the proviso that when X represents (E)-ethylene or (Z)-ethylene, one of R1 and R2 taken together with R3 may not form a direct bond, such that a triple bond is constituted; with the further proviso that when X represents a bond R1 ands R2 are nor hydrogen; with the further proviso that the compound of formula I is not 3(S)-hyroxy-9, 10-secocholesta-5(Z),7(E),10(19),22(E),24-penta-ene; and prodrugs and stereo isomeric forms thereof are provided together with their use in therapy, and their use in the manufacture of medicaments.
根据公式I:其中公式中的R1和R2,可以相同也可以不同,代表卤素,(C1-C6)烃基,可选地在一个或多个氟原子上用一个或两个羟基取代,或者,与它们都连接的碳原子一起,R1和R2形成一个(C3-C6)碳环,或者R1和R2中的一个与R3一起形成直接键,从而构成三键,或者R1和R2都代表氢;当R3不与R1和R2中的一个形成直接键时,代表氢或(C1-C3)烃基;X代表(E)-乙烯,(Z)-乙烯,乙炔基,或者一个键;Y和Z独立地代表氢或甲基;C#16和C#17之间的键用虚线表示,以说明该键可以是单键,此时环取代基的投影为β,或者是双键;A代表羟基,氟或氢;B代表CH2或H2;3位的构型与天然维生素D3 (正常)中的构型相对应,或者3位的构型与天然维生素D3 (epi)中的构型相反;但是当X代表(E)-乙烯或(Z)-乙烯时,R1和R2中的一个与R3一起不能形成直接键,从而构成三键;进一步的条件是,当X代表一个键时,R1和R2不是氢;进一步的条件是,公式I的化合物不是3(S)-羟基-9,10-去甲胆骨化甾-5(Z),7(E),10(19),22(E),24-五烯;还提供了它们的前药和立体异构体形式,以及它们在治疗中的用途,以及它们在药物制造中的用途。
