Abstract:
PURPOSE: Provided is prodigiosin isolated from culture broth of Serratia marcescens. The prodigiosin inhibits specifically immunogenecity of T cell and is used in immunosuppresive drug. CONSTITUTION: A Prodigiosin isolated from culture broth of Serratia marcescens B-1231 (KCTC 0386BP) is represented by the formula (I). The Prodigiosin is prepared by the following steps of: (a) cultivating Serratia marcescens B-1231 (KCTC 0386BP) in a medium comprised of soluble starch of 1%, glucose of 0.25, ammonium sulfate of 0.1%, potassium phosphate of 0.1%, magnesium sulfate- septuple crystal solution of 0.05%, calcium chloride of 0.1 %, sodium chloride of 0.3% at pH value of 7 and temperature of 28 deg.C for 62 hours; (b) mixing them with adding ethyl acetate in a same amount, thereto for 30 minutes, to obtain organic solvent layer; (c) concentrating the mixture under reduced pressure, to obtain a red material; (d) isolating and purifying an active material therefrom; and (e) purifying it by silicagel thin layer chromatography.
