The effects of psoralen and angelicin on hepatic microsomal drug-metabolizing enzyme (DME) activities were investigated to elucidate the mode of the interaction of furanocoumarins with DME system. A single administration (30mg/kg, i.p.) of both coumarins to mice caused a significant prolongation of hexobarbital-induced hypnosis as well as an increase in strychnine toxicity. The inhibitory potencies of both coumarins as measured by rat hepatic microsomal aminopyrine N-demethylase and hexobarbital hydroxylase activitiesin vitro were considerably weaker than those of other furanocoumarins which possess a side chain moiety. Both coumarins were found to have significant inducing effects on DME system, with repeated treatments of them. The activities of an angular coumarin were stronger than those of a linear coumarin.  相似文献

A series of angelicin heteroanalogues, in which the furan was replaced by thiophene or a 1-substituted pyrazole moiety, was synthesised in order to obtain potential therapeutic agents with antiproliferative and/or other biological activities. In general, the antiproliferative activity of the new thioangelicin, tested in different biological substrates, appeared to be higher than that of the angelicin, the natural parent compound, but lower than that of 8-MOP, the furocoumarin ordinarily used in PUVA therapy and photopheresis. Thioangelicin 6 induced strong inhibition of T2 bacteriophage infectivity and was able to significantly repress the DNA synthesis in Ehrlich ascites cells and the clonal growth in HeLa cells. The pyrazolocoumarins did not show any noticeable effect upon UVA irradiation in all the biological systems considered. All the new angelicin heteroanalogues appeared to be free of the known phototoxicity of furocoumarins on the skin. The pyrazolocoumarins have also been tested as anti-inflammatory, analgesic, antipyretic, local anaesthetic, anti-arrhythmic and platelet anti-aggregating agents by standard procedures. In this class of derivatives, 10a showed good anti-inflammatory and antipyretic properties, while 9a and 11a showed significant local anaesthetic activity.  相似文献

Preclinical Research & Development
Angelicin is a furocoumarin derived from Psoralea corylifolia L. fruit that has anti‐inflammatory and anti‐tumor activity. In the present study, the effect of angelicin in enhancing tumor necrosis factor‐related apoptosis‐inducing ligand (TRAIL)‐induced apoptotic cell death was studied in Caki (renal carcinoma) cells. Angelicin alone and TRAIL alone had no effect on apoptosis, but in combination these compounds markedly induced apoptosis in the cancer cell lines while not inducing apoptosis in normal cells. The combination treatment induced accumulation of the sub‐G1 population, DNA fragmentation, and activated caspase 3 activity in Caki cells, induced down‐regulation of c‐FLIP expression post‐translationally, and over‐expression of c‐FLIP markedly blocked apoptosis induced by combined treatment with angelicin plus TRAIL. This study provides evidence that angelicin might be a TRAIL sensitizer.  相似文献

A reversed-phase high performance liquid chromatographic method was developed to determine the contents of psoralen and angelicin from some medicinal herbs. The optimum eluent for chromatography was 20 v/v% acetonitrile in water on a Zorbax 300SB C18 column. The identification was carried out by comparing the retention time and mass spectra of the relevant peaks with their standards. The variation of the concentration of psoralen and angelicin was wide between different species. The seeds of Psoralea corylifolia showed the highest contents of psoralen (7.8 mg/g) and angelicin (2.3 mg/g) among the tested herbs.  相似文献
