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 is a hybrid type air-compressor, which has a main body including a cylinder having upper and lower portions, a motor assembly including an eccentric shaft passing through a side surface of the main body to eccentrically rotate in the cylinder, a first communication part covering an upper portion of the cylinder of the main body and introducing air to discharge the air to the upper portion of the cylinder, a second communication part covering a lower portion of the cylinder of the main body and introducing air to discharge the air to the lower portion of the cylinder; and an air compressing means connected to the eccentric shaft of the motor assembly and vertically moving in the cylinder to alternately compress air introduced into the upper and lower portions of the cylinder.

Abstract: The present invention provides a 3?,4?,5-trimethoxy flavone derivative and a pharmaceutically acceptable salt thereof, preparation thereof, and a pharmaceutical composition for the treatment and prevention of dry eye syndrome comprising the same as an active ingredient. The 3?,4?,5-trimethoxy flavone derivative and its pharmaceutically acceptable salt inhibit corneal damage through excellent stimulatory action on mucus secretion in the conjunctiva and therefore may be effective as a prophylactic or therapeutic agent for dry eye syndrome.
