  • Patent number: 10723699
    Abstract: The present invention relates to a cyclohexene derivative, a preparation method thereof, and a pharmaceutical composition for preventing or treating metabolic disease containing the cyclohexene derivative as an active ingredient. The cyclohexene derivative according to the present invention increases the intracellular activity of cyclic adenosine monophosphate (cAMP) by activating G protein-coupled receptor 119 (GPR-119) and simultaneously exhibits weight loss and hypoglycemic effects by inducing the release of glucagon-like peptide-1 (GLP-1), which is a neuroendocrine protein, and thus can be useful as a pharmaceutical composition for preventing or treating metabolic diseases such as obesity, type 1 diabetes, type 2 diabetes, inadequate glucose tolerance, insulin resistance, hyperglycemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, dyslipidemia and syndrome X.

  • Publication number: 20180344716
    Abstract: The present invention relates to novel derivatives of oxazolidinone, a method thereof and pharmaceutical compositions comprising the derivatives for use in an antibiotic. The oxazolidinone derivatives of the present invention show inhibitory activity against a broad spectrum of bacteria and lower toxicity. The prodrugs, prepared by reacting the compound having hydroxyl group with amino acid or phosphate, have an excellent efficiency on solubility thereof against water. Further, the derivatives of the present invention may exert potent antibacterial activity versus various human and animal pathogens, including Gram-positive bacteria such as Staphylococi, Enterococci and Streptococi, anaerobic microorganisms such as Bacteroides and Clostridia, and acid-resistant microorganisms such as Mycobacterium tuberculosis and Mycobacterium avium. Accordingly, the compositions comprising the oxazolidinone are used in an antibiotic.

  • Publication number: 20160355483
    Abstract: The present invention relates to a compound inhibiting CDK5-mediated PPARG phosphorylation and a pharmaceutical composition for treating PPARG-related diseases containing the same as an active ingredient. A compound represented by formula 1 or an optical isomer thereof according to the present invention that binds to PPARG at a high affinity level, but does not act as an agonist, thereby inducing no gene transcription; blocks CDK5, which is a cause of PPARG phosphorylation, thereby causing no side effects of existing anti-diabetic drugs; can be formulated into drugs due to improved pharmacological properties thereof; and can be favorably used as a pharmaceutical composition for treating PPARG-related diseases due to favorable treatment effects on PPARG-related diseases.
