Compounds of formula (I):
[in which: R1 is hydroxy, protected hydroxy, fluorine, or -OP(0)(OH)2; R2 and R3 are independently optionally substituted C6 - C20 aliphatic acyl; R4 is hydroxy, protected hydroxy, or -OP(O)(OH)2, where at least one of R1 and R4 is -OP(O)(OH)2; and R5 is hydroxy, protected hydroxy, or fluorine; provided that, except where at least one of R1 and R5 is fluorine, then at least one of R2 and R3 is a substituted C6 - C20 aliphatic acyl having (i) at least one halogen substituent and (ii) at least one of halogen, hydroxy and C6 - C20 aliphatic acyloxy or at least one of R2 and R3 is a substituted C6 - C20 aliphatic acyl which is substituted by at least one halogen-substituted C6 - C20 aliphatic carboxylic acyloxy]; have Lipid A-like activity and may be used for the treatment, prophylaxis, diagnosis and support of an animal suffering a disease or disorder arising from a deficiency in the immune system or from a tumor. They may be prepared by phosphorylation of corresponding compounds lacking a phosphoryl group.
式(I)化合物:
其中R1 是羟基、受保护的羟基、氟或-OP(0)(OH)2;R2 和 R3 独立地是任选取代的 C6 - C20 脂肪族酰基;R4 是羟基、受保护的羟基或-OP(O)(OH)2,其中 R1 和 R4 中至少有一个是-OP(O)(OH)2;R5 是羟基、受保护的羟基或氟;条件是,除非 R1 和 R5 中至少有一个是氟,否则 R2 和 R3 中至少有一个是被取代的 C6 - C20 脂肪族酰基,该酰基具有 (i) 至少一个卤素取代基和 (ii) 卤素、羟基和 C6 - C20 脂肪族酰氧基中的至少一个,或者 R2 和 R3 中至少有一个是被至少一个卤素取代的 C6 - C20 脂肪族羧基酰氧基取代的 C6 - C20 脂肪族酰基];具有类似脂质 A 的活性,可用于治疗、预防、诊断和支持因免疫系统缺陷或肿瘤引起的疾病或紊乱的动物。它们可以通过对缺乏磷酸基团的相应化合物进行磷酸化来制备。
