Abstract:
A hydroxamic acid derivative is provided to induce the activity increase of each promoter of IDH3alpha and CPT1 involving with energy consumption metabolism, thereby being usefully used for preventing or treating diseases related to dyslipidemia such as obesity, hyperlipidemia and diabetes. A hydroxamic acid is represented by a formula(1), wherein R1 is CONH, NHCO, CONR4 or NR4CO(where R4 is H or C1-10 alkyl); R2 is -(CH2)n-(where n is 0 or 1); and R3 is H or C1-10 alkyl. A method for preparing the hydroxamic acid comprises the steps of: (a) reacting an anhydrous compound synthesized by reacting ethyl chloroformate with piperonic acid using pyridine or N-methyl morpholine as a solvent with methyl 4-amino benzoate or 4-amino phenyl acetic acid ethyl ester at a temperature of 10-20 deg.C using pyridine or N-methyl morpholine as a solvent to prepare a benzamide compound; (b) reacting the benzamide with an alkyl halide selected from the group consisting of bromomethane, bromoethane, bromopropane, bromo isopropane, bromo butane, and bromo tert-butane to substitute an amide bond of the benzamide with an alkyl group; (c) hydrolyzing methyl ester in the benzamide obtained from the step(a) or the benzamide compound obtained from the step(b) to prepare an acid and reacting the acid with ethyl chloroformate using pyridine or N-methyl morpholine as a solvent to covert the acid into an anhydrous compound; and (d) reacting the anhydrous compound with hydroxyl amine chloride or N-methyl hydroxyl amine chloride at a temperature of 0-10 deg.C using pyridine or N-methyl morpholine as a solvent to obtain the product of the formula(1). An agent for anti-obese, treating diabetes or hyperlipidemia comprises the hydroxamic acid.
Abstract:
A transformed cell line is provided to identify a chemical material controlling expression of an IDH3A gene at a transcription step and also find out an anti-obese material such as genistein. An expression vector pIDH3A comprises: a kanamycin resistant gene(Kana+) and a neomycin resistant gene(Neo+); a luciferase gene(LUC+); and an IDH3A promoter of SEQ ID : NO. 1 and has a structure depicted in Fig. 2. A cell line PRDC IDH3A transformed by the expression vector is deposited as a deposition no. KCTC 10981BP. A method for searching an obesity controlling material comprises the steps of: (a) treating the cell line with an obesity controlling candidate material; and (b) detecting the fluorescence emitting reaction, wherein the obesity controlling candidate material is treated with at least two concentrations.
