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 skin external composition comprising a cathepsin G inhibitor is provided to prevent an adhesion protein from being degraded by intrinsic aging and photo-aging, reduce the production of metalloproteinase and inhibit the activity of metalloproteinase, thereby being more potent anti-aging substance than existing anti-aging substances. A method for screening anti-aging materials is provided to develop the anti-aging materials which effectively inhibit the quantitative and qualitative increase of metalloproteinase, resulting from the degradation of an adhesion protein by cathepsin G in skin cells without direct UV irradiation. A skin external composition for preventing skin aging comprises 0.01-10 wt% a cathepsin G inhibitor as an effective ingredient, wherein the cathepsin G inhibitor is at least one selected from the group consisting of compounds represented by formulae(1) to (4). The composition is formulated into skin lotion, astringent lotion, milk lotion, nourishing cream, essence, massage cream, eye cream, pack, body lotion, body cream, body oil or body essence. A method for screening an anti-aging material comprises the steps of: (a) adding an anti-aging candidate material to a substrate in the presence of cathepsin G enzyme; and (b) measuring the inhibition of activity of the cathepsin G enzyme. Further, the measure of the inhibition of activity of the cathepsin G enzyme is performed by measuring a concentration of a produced metalloprotease.
