Two new quassinoids, brujavanol A (1) and brujavanol B (2), along with five known quassinoids (3–7), were isolated from the roots of Brucea javanica. Their structures were elucidated by spectroscopic methods. The antimalarial and cytotoxic activities of the isolated compounds were also assessed. Compounds 1 and 2 exhibited significant in vitro cytotoxicity against human oral cavity cancer (KB) cells with IC50 values of 1.30 and 2.36 μg/ml, respectively, whereas compound 3 showed excellent antiplasmodial activity against the Plasmodium falciparum strains, K1 (IC50 = 0.58 μg/ml). 相似文献

Introduction
Hepatocellular carcinoma (HCC) is a type of malignancy with high incidence and poor prognosis. Brucea javanica is extracted from Simaroubaceae plants. It is found to have low toxicity but high anti-cancer efficiency. The aim of this study is to determine the effects of Brucea javanica oil-loaded liposomes (BJOL) on human hepatocellular cancer cell line HepG2. The related molecular mechanisms were determined.Material and methods
Morphologic changes of HepG2 cells were observed by transmission electron microscope after treatment with BJOL in vitro. Cell proliferation was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay after cell treatment with different doses of BJOL. Flow cytometry was performed. Nude mice were divided into 4 groups randomly and treated with different doses of BJOL. The apoptosis hepatocellular carcinoma was detected by TUNEL.Results
Proliferation of HepG2 was inhibited significantly by BJOL in a dose-dependent manner (2.5 mg/l or 5 mg/l). Compared with the animal models treated with the negative control, the animal models in the BJOL group had higher weight and lower metastasis rates (p < 0.01). The rate of apoptosis in hepatocellular carcinoma tissue of the BJOL groups was increased when compared with the control group (p < 0.05).Conclusions
Brucea javanica oil-loaded liposomes inhibits proliferation of HepG2. The effect appears to be dose-dependent, possibly by inducing apoptosis of cancer cells. 相似文献7.

Topical application of 100 mg/kg body weight of Ixora javanica flower extract inhibited the growth and delayed the onset of papilloma formation in mice initiated with 7,12-dimethylbenz[a]anthracene (DMBA) and promoted using croton oil. The extract at the same dose, when administered orally inhibited the growth of subcutaneously injected 20-methylcholanthrene (MCA)-induced soft tissue fibrosarcomas significantly. Oral administration of 200 mg/kg of the extract inhibited the growth of intraperitoneally transplanted sarcoma-180 and Ehrlich ascites carcinoma tumours besides showing an increase in the life span of the treated mice. Toxicity studies showed that the blood urea nitrogen levels were elevated post treatment. The active compounds responsible for the above inhibitory effects on tumour growth were identified as ferulic acid (4-hydroxy-3-methoxy cinnamic acid) and its regionmer 3-hydroxy-4-methoxy cinnamic acid. 相似文献
