Antiproliferative effects of total alkaloid extract of roots of Chassalia curviflora (Wall.) Thwaites on cancer cell lines

389-395Chassalia curviflora is used in folklore medicines for treating several ailments and infections owing to its anti-inflammatory properties. Though the plant has been reported to possess anti-inflammatory antihepatotoxic and analgesic activities, its anticancer potential has not been studied so far. In the present study, we investigated the antiproliferative effects of the total alkaloids isolated from the roots of C. curviflora. The total alkaloid was validated by MTT assay in three cancer cell lines, such as liver cancer cell line-A549, breast cancer cell line-MCF-7 and ovarian cancer cell line -HeLa. Significant antiproliferative effect (IC50 value 3.59±0.14*** µg/mL) was observed in A549 cells, and was taken for further studies. Cell cycle analysis showed that the cells got arrested in sub G0 phase and annexin V-FITC assay revealed that 27.4% cells were in early apoptosis and 7% cells in late apoptosis. The study revealed that the total alkaloids of Chassalia curviflora roots possess significant antiproliferative and apoptotic activity

A new paradigm of copper oxide nanoparticles catalyzed reactions: synthesis of 1,2,3-triazoles through oxidative azide-olefin cycloaddition

Oxidative [3 + 2] cycloaddition of activated olefins and azides is reported with readily available CuO nanoparticles. 1,4-Disubsitituted and 1,4,5-trisubstituted 1,2,3-triazoles have been achieved without use of base or additives in a shorter time.</p

Anti-Hepatotoxic Property of Roots and Leaves of Chassalia curviflora (Wall.) Thwaites against CCl4 Induced Liver Damage in Rats

In the present study the roots and leaf ethanolic extracts of Chassalia curviflora were screened for their anti hepatotoxic and anti oxidant effects in experimentally induced liver injury by carbon tetra chloride. Liver serum marker enzymes as well as antioxidant enzymes mainly superoxide dismutase, catalase and glutathione levels were determined. The plant root and leaf ethanolic extracts at 50, 100, 200 mg concentrations significantly (**P ≤ 0.05) reduced the elevated serum hepato specific enzyme [serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), serum alkaline phosphatase (SAKP), serum bilirubin (SB)] and cholesterol levels induced by CCl4. Antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and non enzymatic reduced glutathione (GSH) levels were increased whereas malondialdehyde (MDA) level was reduced by the extracts. Compared to the leaf extract, root extract significantly reduced serum hepato parameters and increased the levels of anti-oxidant enzymes in a dose dependent manner. The results were comparable to that of silymarin, reference drug used for the study. The histopathological studies also supported the biochemical findings. Acute toxicity studies revealed that it is safe for pharmacological uses upto 2000mg/kg. The present study scientifically validated the traditional use of plant root in hepatoprotection.</jats:p
