Claim 4
Dependent Claim
180 words
Compounds represented by the following general formula (A) or pharmaceutically acceptable salts thereof: in which: A is saturated or unsaturated hydrocarbon chain with 1 to 5 carbon atoms which may optionally be substituted with (C 1 ―C 2 -alkyl, hydroxyl, phenyl, ethoxy, phenoxy, phenylthio, halogen, halo-substituted methyl, methyl substituted with dimethylamino or with methylpiperazino, ethoxycarbonyl-substituted (C 1 ―C 2 )-alkyl, carboxysubstituted (C 1 ―C 2 )-alkyl, methoxy-substituted methyl, tetrahydropyranyloxy-methyl, hydroxy-substituted methyl, (C 1 ―C 2 )-acyloxy-substituted methyl, phenylamino, carboxy, nitro, cyano, carbonyl, thiocarbonyl or imino group, wherein A may form a ring, R, is hydrogen, lithium, sodium, potassium, calcium, methyl, ethyl, pivaloyloxymethyl or phthalidyl, R 2 , R 3 , R 4 and R 5 are same or different and they are hydrogen, fluorine, chlorine, bromine, hydroxy, ethoxy or wherein R 3 and R 4 may form a ring and wherein R 6 and R 7 are same or different and they form five to seven-membered heterocyclic ring together with adjacent nitrogen atoms, wherein said heterocyclic ring may contain other hetero atom(s), may have substituent(s) or may form a salt.
