Abstract:

Four ternary rare earth complexes of warfarin(W) and freulic acid(FA), RE(C19H15O4)2·(C10H9O4)·2H2O(RE=La, Nd, Ce, Eu), were obtained via the reaction of ferulic acid and warfarin with rare earth ions in the ethanol solution by solvent-thermal method. The composition of these complexes was characterized by infrared(IR) spectrometry, thermogravimetric-differential thermal analysis(TG-DTA), elemental analysis, X-ray diffraction(XRD) analysis and nuclear magnetic resonance(NMR) spectrometry. Meanwhile, the anticoagulant properties of warfarin, ferulic acid and their complexes were tested by coagulation time(CT), recalcification time(RT), activated partial thromboplastin time(APTT) and prothrombin time(PT) in physiological conditions. The results show that the four ternary rare earth complexes all have better anticoagulant action than the binary complexes of ferulic acid and warfarin in related anticoagulant experiments. The four ternary rare earth complexes could reduce the fluorescence intensity and enhance the UV intensity of human serum albumin(HSA).
