Abstract:
A 1,2,4-thiadiazolidine-3,5-dione compound is provided to be used for synthesizing various 1,2,4-thiadiazolidine-3,5-dione compounds because of substitution of amide at 4-position of a thiadiazolidine-2,5-dione with a thiadiazolidine-3,5-dione as a skeleton. A 1,2,4-thiadiazolidine-3,5-dione compound is represented by a formula(1) and is prepared by hydrolyzing an ester compound represented by a formula(2) to prepare an acetic acid compound represented by a formula(3) and then reacting the compound of the formula(3) with an amine compound represented by a formula(4), wherein R1 is linear or branched saturated or unsaturated C1-7 alkyl, C1-7 alkoxycarbonyl C1-7 alkyl, phenyl, C1-7 alkyl substituted phenyl, benzyl or allyl; R1 and R2 are independent from each other and H, linear or branched saturated or unsaturated C1-7 alkyl, phenyl, halogen substituted phenyl, or R2 and R3 may form a ring, or the ring formed by an alkylene further includes 1-2 heteroatom(s) and may be further substituted by halogen, C1-7 alkyl, hydroxyl or C1-7 alkoxycarbonyl.
Abstract:
A novel 1,2,4-thiadiazolidine-3,5-dione compound is provided to show excellent activity and enzyme selectivity on Lck SH2, thereby being usefully used for treating and preventing inflammation related diseases such as rheumatoid arthritis with high selectivity without side effects. A pharmaceutical composition for treating and preventing a disease induced by inflammation comprises a 1,2,4-thiadiazolidine-3,5-dione compound represented by a formula(1) or a pharmaceutically acceptable salt thereof as an effective ingredient. In the formula(1), A is linear or branched saturated or unsaturated C1-7 alkyl, indenyl, (C1-7)alkoxycarbonyl(C1-7)alkyl, phenyl, benzyl or C2H5(C=O)HR2R3(wherein A may be substituted by halogen, carboxyl, C1-7 alkoxycarbonyl, C1-7 alkoxy, nitro or hydroxy when A is alkyl, phenyl or benzyl); R1 is H, linear or branched saturated or unsaturated C1-7 alkyl, (C1-7)alkoxycarbonyl(C1-7)alkyl, phenyl, phenyl(C1-5)alkyl or phenylcarbonylmethyl; and each R2 and R2 is independently H, linear or branched saturated or unsaturated C1-7 alkyl or phenyl, or R2 and R3 may form a ring together with C1-5 alkylene. A pharmaceutical composition for treating and preventing rheumatoid arthritis comprises the 1,2,4-thiadiazolidine-3,5-dione compound of the formula(1) or a pharmaceutically acceptable salt thereof as an effective ingredient.
