This invention is to provide a compound of the formula:
wherein R1 is an optionally substituted 5- to 6-membered ring; the ring A is an optionally substituted 6- to 7-membered ring; the ring B is an optionally substituted benzene ring; n is an integer of 1 or 2; Z is a chemical bond or a divalent group; R2 is (1) an optionally substituted amino group in which a nitrogen atom may form a quaternary ammonium, (2) an optionally substituted nitrogen-containing heterocyclic ring group which may contain a sulfur atom or an oxygen atom as ring constituting atoms and wherein a nitrogen atom may form a quaternary ammonium, (3) a group binding through a sulfur atom or (4) a group of the formula:
wherein k is 0 or 1, and when k is 0, a phosphorus atom may form a phosphonium; and R5 and R6 are independently an optionally substituted hydrocarbon group, an optionally substituted hydroxy group or an optionally substituted amino group, and R5 and R6 may bind to each other to form a cyclic group together with the adjacent phosphorus atom, or a salt thereof , which is useful for antagonizing CCR5 and also for the prevention and treatment of infectious disease of HIV.
这项发明提供了以下式的化合物:
其中R1是一个可选择取代的5至6成员环;环A是一个可选择取代的6至7成员环;环B是一个可选择取代的苯环;n是1或2的整数;Z是化学键或二价基团;R2是(1)一个可选择取代的氨基团,其中氮原子可以形成季铵盐,(2)一个可选择取代的含氮杂环环基团,可能含有硫原子或氧原子作为环构成原子,其中氮原子可以形成季铵盐,(3)通过硫原子结合的基团或(4)下式的基团:
其中k为0或1,当k为0时,磷原子可以形成磷铵盐;R5和R6分别是可选择取代的碳氢基团、可选择取代的羟基或可选择取代的氨基团,R5和R6可以结合在一起与相邻的磷原子形成环状基团,或其盐,用于拮抗CCR5并用于预防和治疗HIV感染疾病。
