Several methods exist for the treatment of cancer in modern medicine. These include chemotherapy, radiotherapy, and surgery; most cancer chemotherapeutants severely affect the host normal cells. Hence the use of natural products now has been contemplated of exceptional value in the control of cancer. Plant-derived natural products such as flavonoids, terpenes, alkaloids, etc., have received considerable attention in recent years due to their diverse pharmacological properties including cytotoxic and cancer chemopreventive effects. Looking into this, the antioxidant and anticancer evaluation of Scindapsus officinalis (Roxb.) Schott fruits has been attempted to investigate its antitumor activity. The collection and authentication of the plant material mainly fruits and their various extractions was done. Identification of plant's active constituents by preliminary phytochemical screening was carried out. An in-vitro cytotoxic assay using the brine shrimp lethality assay with brine shrimp eggs (Artemia salina) at a dose of 1-10 µg/ml with the fruit extract was performed by the method described by Mayer et al. Cell viability using the Trypan blue dye exclusion test at a dose of 20, 40, 80, 120, and 160 µg/ml dissolved in DMSO (final concentration 0.1%), and cytotoxicity using the MTT assay where viable cells convert MTT into a formazan salt were performed. All pharmacological screening for acute toxicity and anti tumour studies using EAC 1 x 106 cells/mouse treated Swiss albino mice at a dose of 100 and 200 mg/kg/day orally was carried out. Biochemical and antioxidants predictions from various parameters like hematological, RBC, WBC count, PVC, total protein, Tissue Lipid Peroxidation, SOD, CATALASE, GPx, GST levels and anti tumour activity of Scindapsus officinalis were observed. The data was statistically analyzed by one-way ANOVA followed by Dunnett's and Tukey's multiple comparison test. The antitumor effect of the extract is evident from the increase in mean survival time (MST) lifespan, reduction in the solid tumor volume, and also the reversal of altered hematological parameters almost equal to normal. The methanolic extract (100-200 mg/kg/day orally) was found to be cytotoxic on human cancer cell lines. In addition, the methanolic extract had an antioxidant effect as reflected by a decrease in LPO, GST, and GPx (oxidant enzymes), and an increase in SOD and catalase. [ABSTRACT FROM AUTHOR] |
