Abstract:
A compound represented by Formula: wherein ring A and ring B may be same or different and each is an optionally substituted homocyclic or heterocyclic ring, wherein the substituents on ring A and ring B may be bound to each other and taken together with ring A, ring B and X2 to form a condensed ring, each R1 may be same or different and is a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group, an optionally substituted heterocyclic group or SR2, wherein R2 is a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group or an optionally substituted heterocyclic group, X1 is an optionally substituted divalent C1-3 aliphatic hydrocarbon group or â€”NR3â€”, wherein R3 is a hydrogen atom, an optionally substituted hydrocarbon group or an acyl group, X2 is a bond, an optionally substituted divalent C1-3 aliphatic hydrocarbon group, â€”NR4â€”, â€”Oâ€” or â€”S(O)pâ€”, wherein R4 is a hydrogen atom, an optionally substituted hydrocarbon group or an acyl group, and wherein p is 0, 1 or 2, each Y may be same or different and is a hydrogen atom, an optionally substituted hydrocarbon group, a halogen atom, a carboxyl group, an acyl group, an optionally substituted hydroxy group, an optionally substituted amino group, SR5, an oxo group, a thioxo group, an optionally substituted imino group, a nitro group or a cyano group, wherein R1 is a hydrogen atom, an optionally substituted hydrocarbon group, an acyl group or an optionally substituted heterocyclic group each m may be same or different and is 0 or 1, n is 1, q1 is an integer of 1 to 2n+4, q2 is an integer of 0 to 2n+3, and the sum of q1 and q2 is 2n+4, provided that when ring B is a nitrogen-containing heterocyclic ring then X2 binds to a position capable of being substituted except for a nitrogen atom on ring B, or a salt thereof.
