摘要:
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.

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.
