<p>This invention is to provide a pharmaceutical composition for antagonizing CCR5 which comprises a compound of formula (I) wherein R1 is an optionally substituted 5- to 6-membered ring; W is a divalent group of formula (a) or (b) wherein the ring A is an optionally substituted 5- to 6-membered aromatic ring, X is an optionally substituted C, N or O atom, and the ring B is an optionally substituted 5- to 7-membered ring; 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 formula (II) wherein k is 0 or 1, and when k is 0, a phosphorus atom may form a phosphonium; and R?5' and R6'¿ are independently an optionally substituted hydrocarbon group, an optionally substituted hydroxy group or an optionally substituted amino group, and R?5' and R6'¿ may bind to each other to form a cyclic group together with the adjacent phosphorus atom, or a salt thereof.</p> |
