| Description | 2,3-Dehydrokievitone, an isoflavone extracted from Erythrina sacleuxii, has antimicrobial activity against methicillin-resistant Staphylococcus aureus infections by decreasing the expression of α-hemolysin. |
| In vitro | To evaluate the anti-oxidative effects of these compounds, their 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assays and nitrotetrazolium blue chloride (NBT) superoxide scavenging assays were measured. And the anti-tumor activity against human cancer cell lines in genital system, LNCaP, PC-3,HeLa and OVCAR-3 cells were evaluated by MTT method. Furthermore, the apoptosis of the PC-3 and HeLa cells were determined by by annexin V-FITC and PI their fluorescence was analyzed by flow cytometry. The flavonol (9, isoquercitrin) and pterocarpan (8, 4-hydroxymaackiain) showed strong anti-oxidative activities. Besides, the isoflavones (1-5) did not showed anti-oxidative activity and the isoflavones (1-5) and pterocarpans (6-8) generally showed the potent cytotoxic activity against all of four human genital cancer cells. Especially, 2,3-Dehydrokievitone (5) which had a prenyl group at C-8 position of the A-ring exhibited strong cytotoxic activity and induced apoptosis efficiently in cancer cells. |
