Abstract: The present invention relates to a benzamide derivative compound, a method for preparing the same, and a pharmaceutical composition for treating or preventing an inflammatory disease containing the same as an active ingredient. The benzamide derivative compound according to the present invention inhibits the expression of PDE4 and regulates the expression of an inflammatory disease-related substance such as IL-4 (interleukin-4), IL-5 (interleukin-4), IFN-? (interferon-?), IL-17 (interluekin-17), IgE (immunoglobulin E), and TNF-? (tumor necrosis factor-?), and thus may be utilized as a pharmaceutical composition for treating or preventing an inflammatory disease.

Abstract: The present invention relates to a silver/polydiguanide complex and derivatives thereof including silver and polydiguanide having at least two biguanide moieties, wherein the silver is stabilized in an oxidation state of an integer of 0 to 4, a mole ratio between the silver and the polydiguanide is 1:1-4, an average particle diameter of the complex is micrometer or nanometer, and zeta potential of the complex is greater than or equal to zero, a preparation method thereof, and an antibacterial composition for burns or wounds treatment including the same as an active ingredient.
