Abstract:
The present invention relates to a compound derived from Serratia sp. and a use of the same and, more specifically, to a compound derived from Serratia sp. having an excellent antioxidant activity and a use of the same. Serratinin which is a compound derived from Serratia sp. PAMC 25557 according to the present invention has an excellent free radical eradicating activity compared to existing antioxidant agents and exhibits good thermal stability in a wide range of temperatures. The same also has an excellent chelating activity for Fe^2^+ so that the same, as a preemptive antioxidant material, can replace an existing synthetic antioxidant agent.
Abstract:
PURPOSE: A composition for the prevention and treatment of arteriosclerosis containing a novel compound of stereocalpin-A is provided to suppress the expression of VCAM-1 and ICAM-1 induced by TNF-alpha due to the incapability of signal transduction to MAP kinse, Akt, and NF-kB by the suppression of the ROS production. CONSTITUTION: A pharmaceutical composition for the prevention and treatment of arteriosclerosis comprises stereocalpin-A represented by chemical formula 1 as an active ingredient. The stereocalpin-A represented by the chemical formula 1 is contained at 0.01-10 parts by weight based on 100 parts by weight of composition. The stereocalpin-A represented by chemical formula 1 suppresses the expression of cell adhesion molecules which induces the TNF-alpha. The cell adhesion molecules are ICAM-1 or VCAM-1. The stereocalpin-A is originated from Ramalina terebrata.
