Abstract: The present invention relates to a pharmaceutical composition for the prevention and treatment of diabetes or obesity comprising as active ingredients a compound which inhibits the activity of dipeptidyl peptidase-IV (DPP-IV), a pharmaceutically acceptable salt thereof, a hydrate thereof, or a solvate thereof, and one or more other antidiabetic or antiobesity agents. The pharmaceutical composition exhibits excellent glucose tolerance and may be useful in the prevention and treatment of diabetes, obesity, and the like by effectively inhibiting blood glucose levels and reducing fat mass.

Abstract: Disclosed herein are novel 1,3-dihydro-5-isobenzofurancarbonitrile derivatives represented by Formula 1, or pharmaceutically acceptable salts thereof. Also disclosed is a pharmaceutical composition for treating or preventing premature ejaculation including the compound. The 1,3-dihydro-5-isobenzofurancarbonitrile derivatives have a short half-life and inhibit the ejaculation process by selectively inhibiting serotonin reuptake via a serotonin reuptake transporter present in a presynaptic neuron. Thus, the compounds are useful in the treatment and prevention of premature ejaculation.

Abstract: Disclosed herein is a therapeutic agent for chronic heart failure comprising, as an effective ingredient, 5-[2-propyloxy-5-(1-methyl-2-pyrrolidinyl-ethylamidosulfonyl)phenyl]-1-methyl-propyl-1,6-dihydro-7H-pyrazolo(4,3-d)pyrimidine-7-one. The compound inhibits phosphodiesterase-5 (PDE-5), which catalyzes the intracellular degradation of cyclic guanosine monophosphatase (cGMP), thereby mitigating several signs of chronic heart failure, that is, thereby preventing left ventricular dilatation, decreasing ventricular wall thinning, lowering elevated cardiac and circulating levels of atrial natriuretic peptide (ANP), and inhibiting ventricular fibrosis. Also, the compound has advantages in that it reaches the maximal plasma level in a short time, has an in vivo half-life longer than conventional PDE-5 inhibitors, allowing decreased administration frequency, and has fewer side effects, thus ensuring safety. Thus, the compound is useful as a therapeutic agent for chronic heart failure.
