Claims
- 1. A carboxylic acid compound of the formula (I-a) wherein;R is a piperazinyl optionally substituted by lower alkyl, a piperidyl optionally substituted by lower alkyl or an amino wherein amino is optionally substituted by lower alkyl; A is a linear alkylene; X is an oxygen atom, a sulfur atom, —NH— or CH2—; M is an arylene; and R1, R2, R3 and R4 are the same or different and each is a hydrogen atom, a hydroxy, a halogen atom, or —O—CO—R11″′, provided at least one of R1, R2, R3 and R4 is not a hydrogen atom, and provided one of R1, R2, R3 and R4 is a hydroxyl group with the other groups not being a hydroxyl group. wherein R11″′ is a lower alkyl optionally substituted by a substituent selected from the group consisting of amino, acyloxy and benzyloxycarbonyl, or phenyl optionally substituted by lower alkyl.
- 2. An amide compound of the formula (I-b) X is an oxygen atom, a sulfur atom or —NH—; M is an arylene; R1, R2, R3 and R4 are the same or different and each is a hydrogen atom, a hydroxy, a halogen atom, or —O—CO—R11″′, provided at least one of R1, R2, R3 and R4 is not a hydrogen atom, wherein R11″′ is lower alkyl optionally substituted by a substituent selected from the group consisting of amino, acyloxy and benzyloxycarbonyl, or a phenyl optionally substituted by a lower alkyl; R5 is a hydrogen atom; m is 1; R6 is a phenyl; and R7 is —COO—R12′″wherein R12′″ is hydrogen atom, aralkyl, adamantyl, cyclohexyl-ideneamino, piperidyl optionally substituted by lower alkyl, cyclohexyl optionally substituted by lower alkyl, or alkyl optionally substituted by a substituted selected from the group consisting of hydroxy, lower alkoxy, lower alkoxy lower alkoxy, lower alkoxycarbonyl, acyloxy, piperazinyl, and amino optionally substituted by lower alkyl.
