A compound represented by the formula:
wherein R
1
is a 5- or 6-membered ring; R
3
is a hydrogen atom, a lower alkyl group or a lower alkoxy group; R
7
and R
8
are each a hydrogen atom or a lower alkyl group; Z
1
is another 5- or 6-membered aromatic ring; Z
2
is a group represented by -Z
2a
-W
1
-Z
2b
- [wherein Z
2a
and Z
2b
are each O, S(O)
m
(wherein m is 0, 1 or 2), an imino group or a bond, and W
1
is an alkylene chain]; X is CR (wherein R is a hydrogen atom, a lower alkyl group, a lower alkoxy group, an acyl group, or R and adjacent R
4
may form a 5- or 6-membered alicyclic heterocyclic group) or N; R
4
is NR
5
R
6
(wherein R
5
and R
6
are each a hydrogen atom, a hydrocarbon group, a heterocyclic group or an acyl group), or R
5
and R
6
are bonded to each other to form a heterocyclic group of NR
5
R
6
; and R
2
is (1) an amino group which may be a quaternary ammonium or oxide, (2) a nitrogen-containing heterocyclic group which may contain a sulfur atom or an oxygen atom as the ring-constituting atom, in which the nitrogen atom may be converted to a quaternary ammonium or an oxide, or the like;
or a salt thereof. The compound has excellent CCR5 antagonistic activity and thus is useful as a prophylactic and/or therapeutic medicine for HIV infection into human peripheral blood monocyte, especially for AIDS.
该化合物的化学式为:其中R1是一个5-或6-成员环;R3是氢原子,低烷基或低烷氧基;R7和R8分别是氢原子或低烷基;Z1是另一个5-或6-成员芳香环;Z2是一个由-Z2a-W1-Z2b-表示的基团[其中Z2a和Z2b分别是O,S(O)m(其中m为0,1或2),亚胺基或键,W1是一个烷基链];X为CR(其中R为氢原子,低烷基,低烷氧基,酰基或R和相邻的R4可能形成一个5-或6-成员脂环杂环基)或N;R4为NR5R6(其中R5和R6分别是氢原子,碳氢基团,杂环基或酰基),或R5和R6连接在一起形成一个NR5R6的杂环基;R2是(1)可能是季铵盐或氧化物的氨基基团,(2)可能包含硫原子或氧原子作为环构成原子的含氮杂环基团,在该基团中,氮原子可以转化为季铵盐或氧化物,或类似物;或其盐。该化合物具有优异的CCR5拮抗活性,因此可用作预防和/或治疗人外周血单核细胞HIV感染,特别是艾滋病的药物。
