The most common neoplasms in intact female dogs are CMGTs. BmKn-2, an antimicrobial peptide, is derived from scorpion venom and has published anticancer effects in oral and colon human cancer cell lines. Thus, it is highly likely that BmKn-2 could inhibit CMGT cell lines which has not been previously reported. This study investigated the proliferation and apoptotic properties of BmKn-2 via Bax and Bcl-2 relative gene expression in two CMGT cell lines, metastatic (CHMp-5b) and non-metastatic (CHMp-13a). The results showed that BmKn-2 inhibited proliferation and induced apoptosis in the CMGT cell lines. The cell morphology clearly changed and increased apoptosis in a dose dependent of manner. The half maximum inhibitory concentration (IC50) was 30 µg/mL for CHMp-5b cell line and 54 µg/mL for CHMp-13a cell line. The induction of apoptosis was mediated through Bcl-2 and Bax expression after BmKn-2 treatment. In conclusion, BmKn-2 inhibited proliferation and induced apoptosis in both CHMp-5b and CHMp-13a cell lines via down-regulation of Bcl-2 and up-regulation of Bax relative mRNA expression. Therefore, BmKn-2 could be feasible as candidate treatment for CMGTs.

Objective: The current study is carried out to evaluate cytotoxicity activity of the methanolic extracts of some medicinal plants (Buchanania axillaris Desr, Tamilnadia ulignosa Retz, Phaseolus semierectus L and Stylosanthes fruticosa Retz).Methods: Cytotoxicity activity was evaluated on human cancer cell lines such as lung cancer (A549) and skin cancer (A431) using MTT assay method.Results: The selected plant extracts showed the dose-dependent cytotoxicity activity on the tested cell lines. The cytotoxicity variations on different cell lines were also observed for tested plants extracts. The cytotoxicity of the extracts was increased as the concentration of them was increased. Among all tested plants extracts Phaseolus semierectus showed the better cytotoxicity activity on tested cell lines.Conclusion: The results of the present study supported the folkloric usage of the studied plants and confirmed that the plant's extracts have the bioactive constituents with cytotoxic properties and their isolation can be useful for developing new anticancer drugs.

G Quadruplex

Oligonucleotides with an antiproliferative activity for human cancer cells have attracted attention over the past decades; many of them have a G-quadruplex structure (GQ), and a cryptic target. In particular, DNA oligonucleotide HD1, a minimal GQ, could inhibit proliferation of some cancer cell lines. The HD1 is a 15-nucleotide DNA oligonucleotide that folds into a minimal chair-like monomolecular antiparallel GQ structure. In this study, for eight human cancer cell lines, we have analyzed the antiproliferative activities of minimal bimodular DNA oligonucleotide, biHD1, which has two HD1 modules covalently linked via single T-nucleotide residue. Oligonucleotide biHD1 exhibits a dose-dependent antiproliferative activity for lung cancer cell line RL-67 and cell line of central nervous system cancer U87 by MTT-test and Ki-67 immunoassay. The study of derivatives of biHD1 for the RL-67 and U87 cell lines revealed a structure-activity correlation of GQ folding and antiproliferative activity. Therefore, a covalent joining of two putative GQ modules within biHD1 molecule provides the antiproliferative activity of initial HD1, opening a possibility to design further GQ multimodular nanoconstructs with antiproliferative activity—either as themselves or as carriers.

Azepinobisindole derivatives, the isomeric Iheyamine skeleton, was prepared and its anticancer activity evaluation were investigated against two human cancer cell lines, Hepatocellular carcinoma (HepG2) and human cervical cancer line (Hela) as well as the normal cell line (Vero cell line) using MTT assay. The anticancer activity results indicated that 2-methoxy-5-methyl-5H-azepino[2,3-b:4,5-bʹ]diindole was the most active derivative against tested cell lines. Additionally, molecular docking study in silico the possible inhibitory effect of cyclin-dependent kinase 2 (CDK2) by the azepinoindole revealed that all synthesized compounds fit well in the binding cavity of CDK2.

Luvunga scandens belongs to the family of Rutaceae which usually inhabit tropical and moist environment. This plant is known as ‘Mengkurat Jakun’ among locals and used traditionally to treat fever and fatigue via decoction. The aim of this study was to investigate the cytotoxic activity of the leaves and stems extracts of L. scandens extract. Extracts of the leaves and stems were obtained from sequential extraction procedures by various organic solvents. All extracts were subjected to cytotoxic study by 3-(4, 5-dimethylthaizol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. In in vitro cytotoxicity assay, all L. scandens extracts exhibited cytotoxicity against human breast adenocarcinoma (MCF-7) and human lung adenocarcinoma (A549) cell lines. The IC50 values of dichloromethane and methanol extracts from the leaves of L. scandens against MCF-7 cell line were 62.5 µg/mL and 88.0 µg/mL, respectively, whereas IC50 of methanol extract from stem was 81.0 µg/mL. All extracts were less active against A549 cell line where IC50 value were not be determined. The present findings revealed the potential of L. scandens as a cytotoxic agent against MCF-7 cell line. However, further studies should be planned to evaluate role of the plant in cytotoxic activity.

The aerial parts of Pituranthos tortuosus (Desf.) Benth and Hook (Apiaceae), growing wild in Egypt, yielded 0.8%, 0.6%, and 1.5% (v/w) of essential oil when prepared by hydrodistillation (HD), simultaneous hydrodistillation-solvent (n-pentane) extraction (Lickens- Nickerson, DE), and conventional volatile solvent extraction (preparation of the “absolute”, SE), respectively. GC-MS analysis showed that the major components in the HD sample were β-myrcene (18.81%), sabinene (18.49%), trans-iso-elemicin (12.90%), and terpinen- 4-ol (8.09%); those predominent in the DE sample were terpinen-4-ol (29.65%), sabinene (7.38%), γ-terpinene (7.27%), and β-myrcene (5.53%); while the prominent ones in the SE sample were terpinen-4-ol (15.40%), dill apiol (7.90%), and allo-ocimene (4E,6Z) (6.00%). The oil prepared in each case was tested for its cytotoxic activity on three human cancer cell lines, i.e. liver cancer cell line (HEPG2), colon cancer cell line (HCT116), and breast cancer cell line (MCF7). The DE sample showed the most potent activity against the three human cancer cell lines (with IC50 values of 1.67, 1.34, and 3.38 μg/ml against the liver, colon, and breast cancer cell lines, respectively). Terpinen-4-ol, sabinene, γ-terpinene, and β-myrcene were isolated from the DE sample and subjected to a similar evaluation of cytotoxic potency; signifi cant activity was observed
