| abstract |
The present invention provides a compound represented by the formula: n nwherein R 1 is a 5- or 6-membered ring which may be substituted;n R 3 is a hydrogen atom, a lower alkyl group or a lower alkoxy group; Z 1 is a 5- or 6-membered aromatic ring; Z 2 is a group represented by -Z 2a -W 2 -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 2 is an alkylene chain which may be substituted; n is an integer of 0 to 4; Y is O, S(O) p (wherein p is 0, 1 or 2), CH 2 or NR 4 (wherein R 4 is a hydrogen atom, a hydrocarbon group, a heterocyclic group, or an acyl group); and R 2 is (1) an amino group, in which the nitrogen atom is converted to quaternary ammonium or oxide, (2) a nitrogen-containing heterocyclic group which may contain a sulfur atom or an oxygen atom as a ring-constituting atom, in which the nitrogen atom may be converted to a quaternary ammonium or an oxide, and the like, or a salt thereof. n The compound has excellent CCR5 antagonist activity and is useful as a prophylactic and/or therapeutic medicine for HIV infection in human peripheral mononuclear blood cells, especially AIDS. |
