cancer is a major global problem and is the second leading cause of mortality in the developed countries.resistance to current chemotherapeutics and high incidence of adverse effects are the two principal reasons for developing new anticancer agents. phenylacetamide derivatives can act as potential anticancer agents. synthesis and screening of 2-(4-fluorophenyl)-n-phenylacetamide derivatives in...

A series of fluorinated tetrahydropyrano[3,2-c]chromenes and dihydropyrano[3,2-b]pyran derivatives have been synthesized and their in vitro cytotoxic activities have been determined in cervical cancer cell line (HeLa), human breast adenocarcinoma cell line (MDA-MB-231 and MCF-7) and human alveolar adenocarcinoma cell line (A549). Compounds 4g, 4k, 4p showed a very potent activity against MDA-MB...

Background: Heme oxygenase-1 (HO-1) is a cytoprotective and antiapoptotic enzyme, which has been involved in maintaining cellular homeostasis, and plays an important protective role by modulating oxidative injury. Up-regulation of (HO-1) has contributed to tumorogenicity of some cancers. In this study we investigated the expression pattern of the HO-1, in five different human-derived cancer cel...

Peroxiredoxin (Prdx) proteins are thiol-specific antioxidants that protect cells from oxidative stress in many normal and disease states. There are six Prdx proteins expressed in mammals, each with a characteristic tissue expression, subcellular distribution and substrate specificity. Recent studies have revealed elevated Prdx levels in many cancers, suggesting a protective role for these prote...

a new series of 1,2-diaryl-4,5,6,7-tetrahydro-1h-benzo[d]imidazoles, possessing trimethoxy phenyl pharmacophore, were synthesized to evaluate their biological activities as tubulin inhibitors. cytotoxic activity of the synthesized compounds 7a-f was assessed against several human cancer cell lines, including mcf-7 (breast cancer cell), hepg2 (liver hepatocellular cells), a549 (adenocarcinomic h...

background :many breast cancer tumor suppressor genes have been reported to undergo hypermethylation, including er, rassf1a, hic, cdh1, gspt1, apc, twist and ccnd2. we first determined the promoter methylation of the above eight tumor suppressor genes as epigenetic markers of breast cancer in three cell lines with different er status. methods : this study was an experimental study performed on ...

marine streptomyces are prolific producers of majority of bioactive secondary metabolites which are used in pharmaceutical industry as effective drugs against life threatening diseases. the cytotoxic activity of the pure compound 1, 2- benzene dicarboxylic acid, mono 2- ethylhexyl ester (dmehe) from marine derived actinomycete streptomyces sp. vitsjk8 was investigated against mouse embryonic fi...

BACKGROUND Polybrominated diphenyl ethers (PBDEs), commonly used in building materials, electronics, plastics, polyurethane foams, and textiles, are health hazards found in the environment. OBJECTIVE In this study we investigated the effects of PBDE-209, a deca-PBDE, on the regulation of growth and apoptosis of breast, ovarian, and cervical cancer cells as well as the underlying protein alter...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

Natural products are the best source for various medicinal drugs. Regardless investigate the toxic effect of these plant extracts, the results will still unsafe and unacceptable. This study aimed to identify anti-cancer activity and cytotoxicity effect of Momordica charantia extract on different cancer cell line. Materials and Methods:to archive the aim of this study 3 different cancer cell lin...
