PURPOSE: Benzopyran derivatives substituted by secondary amine containing imidazole and a method for preparing the same are provided. The compounds are useful for treatment of cancer, diabetic retinopathy and external brain wound. CONSTITUTION: Benzopyran derivatives substituted by secondary amine containing imidazole represented by the formula(1), partial stereo isomers thereof and pharmaceutically acceptable salts thereof are provided, wherein R1 is H, CN, NO2 or NH2; R2 is CH3, CHORaRa or CHOOZ; Ra is C1-C4 linear or branched chain alkyl; Z is C2-C6 linear or branched chain alkyl; R3 and R4 are independently H, Cl, Br, F, C1-C3 linear or branched chain alkyl, ORb, CF3, OCF3, NO2 or CO2Rb; Rb is H or C1-C3 alkyl; and * is chiral carbon. A method for preparing the compound of the formula(I) comprises reacting epoxide compounds of the formula(II) with imidazole containing secondary amine compounds of the formula(III) in the presence of metal salt and a solvent, wherein the metal salt is selected from Mg(ClO4)2, COCl2, LiClO4, NaClO4, CaCl2, ZnCl2, LiBF4 and Zn(Tf)2; and the solvent is selected from acetonitrile, tetrahydrofuran and dimethylformamide.
Abstract:
PURPOSE: A pharmaceutical composition containing myxochelin-A which exhibits excellent anticancer activity against human cancer cells, together with excellent antioxidant activity as a main component is provided which can be effectively used as an effective antioxidant and anticancer agent. CONSTITUTION: The pharmaceutical composition contains myxochelin-A of formula 1 obtained by being separated from myxobacteria or being chemically synthesized or semisynthesized. The myxochelin-A is purely separated by the steps of: separating a biomass and absorption resin by culturing Angiococcus disciformis strains as myxobacteria in the presence of absorption resin and centrifuging a culture solution; adding an organic solvent, preferably a mixed solvent of acetone and methanol; extracting and filtering to remove the biomass and absorption resin; preparing an active fraction by concentrating the filtrate under reduced pressure and extracting a crude extract in an organic solvent; and successively performing silica gel liquid chromatography and recycling preparative HPLC.
