Collectively, these results demonstrate that the NCV particles can be used to reduce CRF without much affecting the anti-cancer properties of cisplatin.

Sophora interrupta belongs to the family of Fabaceae and the species in this genus have a diverse medicinal importance as a folk medicine for preventing many ailments including cancer. In order to evaluate the anticancer activity of S.interrupta, we have performed in vitro anti-oxidant, anti-inflammatory, anti-proliferative, and cell based anticancer activity in MCF-7 and PC-3 cell lines. Secondary metabolites of S.interrupta were used to identify anticancer compounds using Open Eye software. The antioxidant activity of the S.interrupta root ethylacetate (SEA) extract at 100 µg/ml is equal to that of ascorbic acid at 50 µg/ml. The antiinflammatory activity of SEA is half of that of diclofenac at 50 µg/ml. Anticancer activity was detected by measuring the mitochondrial dehydrogenase activity (MTT assay). The half maximal inhibitory concentrations (IC50) for MCF-7 and PC-3 cell lines are 250 and 700 µg/ml respectively. This was supported by the morphological changes such as membrane blebbing, cell detachment and rounded cell morphology when compared to the parental cells. In addition, we observed few green cells (live) over red cells (dead) based on the uptake of acridine orange and ethidium bromide dyes. Kaempferol-3-O-b-D-glucopyranoside, a Secondary metabolite of S.interrupta form 6 hydrogen bond interactions with Arg 202, Gln 207, Gly 227, Gly 229, Thr 231 and Ala 232 human DEAD box RNA helicase, DDX3 protein and is equivalent to crystal structure of adenosine mono phosphate to DDX3. Overall, it suggests that the SEA extract has anticancer compounds, and it can be used to enhance death receptor mediated cancer cell death.

Sophora interrupta Bedd, (Fabaceae) is used in Indian folk medicine to treat cancer. Angiogenesis is one of the crucial characteristics of cancer metastasis and is regulated by vascular endothelial growth factor (VEGF). In this study, we examined the antiangiogenic properties of the root ethyl acetate extract of Sophora interrupta by various methods. In vitro antioxidant activity (100-600 μg/ml) of S. interrupta ethyl acetate (SEA) extract was evaluated by DPPH and ABTS, anti-inflammatory activity (50, 100 and 150 μg/ml) by estimating nitric oxide (NO) levels, anti-angiogenic activity (200 and 500 μg/ml) was validated by chorio allantoic membrane (CAM) assay and in silico molecular dynamic (MD) simulations analyses (25 ns) were performed to identify the anti-angiogenic compounds extracted from root extract. The antioxidative activity of SEA extract at IC (200 ± 0.6 μg/mL) is equal to that of ascorbic acid at IC (50 ± 0.6 μg/mL), and the anti-inflammatory activity of SEA extract at IC (150 ± 0.2 μg/mL) was inhibited significantly by nitric oxide (NO) production. The SEA extract significantly reduced the sprouting of new blood vessels at ID 500 ± 0.13 μg/mL in the CAM assay. Gas chromatography-mass spectrometry analysis of the SEA extract detected 34 secondary metabolites, of which 6a,12a-dihydro-6H-(1,3)dioxolo(5,6)benzofuro(3,2-c)chromen-3-ol (maackiain) and funiculosin formed strong hydrogen bond interactions with Lys 920, Thr 916 and Cys 919 (2H), as well as Glu 917 of VEGFR2, and these interactions were similar to those of the anti-angiogenic compound axitinib. Significant findings in all the assays performed indicate that SEA extract has potential anti-angiogenic compounds that may interfere with VEGF-induced cancer malignancy.

Follicle stimulating hormone (FSH) is a glycoprotein secreted by gonadotrophs of the anterior pituitary gland that regulates reproduction in mammals. FSH targets its receptor (FSHR) expressed only on grannulosa cells and induce the maturation of ovarian follicles in females. The levels of both FSH and FSHR rise until the middle of estrus cycle and then falls on level at the time of ovulation. It is associated with stimulated sertoli cell proliferation in testes and supports spermatogenesis in males. The interaction between the polypeptide FSH hormone and its corresponding receptor is highly selective. Therefore, it is of interest to inhibit FSH in the context of infertility. The structure of FSH (PDB ID: 1XWD) is screened using molecular docking techniques against the ZINC database (a database of 2.7 million compounds) with reference to known standard compounds. This exercise identifies compounds with better binding and ADMET (Absorption, Digestion, Metabolism, Excretion and Toxicity) properties compared to known standard compounds. These observations find application for the consideration of such compounds for further validation towards inhibiting the FSH.

Cyperus scariosus (R.Br) belongs to the family Cyperaceae and it has a diverse medicinal importance. To identify human cyclooxegenase-2 (COX-2) inhibitors from C. scariosus, the rhizome powder was exhaustively extracted with various solvents based on the increasing polarity. Based on the presence and absence of secondary metabolites, we have selected the methanolic extract to evaluate the anti-oxidant and anti-inflammatory activity. The same extract was further subjected to gas chromatography-mass spectroscopy (GC-MS) analysis to identify the active compounds. Binding affinities of these compounds towards anti-inflammatory protein COX-2 were analyzed using molecular docking interaction studies. Phytochemical analysis showed that methanol extract is positive for all secondary metabolites. The antioxidant activity of the C. scariosus rhizomes methanolic extract (CSRME) is half to that of ascorbic acid at 50 µg/ml. The anti-inflammatory activity of CSRME is higher than that of diclofenac sodium salt at high concentration, which is evident from the dose dependent inhibition of bovine serum albumin denaturation at 40 µg/ml–5 mg/ml. GC-MS analysis showed the presence of nine compounds, among all N-methyl-1-adamantaneacetamide and 1,5,diphenyl-2H-1,2,4- triazine form a hydrogen bond interactions with Ser-530 and Tyr-385 respectively and found similar interactions with crystal structure of diclofenac bound COX-2 protein. Benzene-1, 2-diol, 4-(4-bromo-3 chlorophenyl iminomethyl forms hydrogen bond interactions with Thr-199 and Thr-200 as similar to crystallized COX-2 protein with valdecoxib. Collectively our results suggest that CSRME contains medicinally important anti-inflammatory compounds and this justifies the use of this plant as a folklore medicine for preventing inflammation associated disorders.
