The synthesis of biologically active 1,4-dihyripyridine derivatives using a Calotropis gigantea leaf powder and ZnO NPs used as catalyst under solvent-free conditions at room temperature via grinding method has been established in single-stage, mild, environmentally friendly green process. procedure is fast effective produces high yields. Three cancer cell lines were to assess the cytotoxic act...

Members of the caspase family of cysteine proteases coordinate cell death through restricted proteolysis of diverse protein substrates and play a conserved role in apoptosis from nematodes to man. However, while numerous substrates for the mammalian cell death-associated caspases have now been described, few caspase substrates have been identified in other organisms. Here, we have utilized a pr...

Quinols have been developed as a class of potential anti-cancer compounds. They are thought to act as double Michael acceptors, forming two covalent bonds to their target protein(s). Quinols have also been shown to have activity against the parasite Trypanosoma brucei, the causative organism of human African trypanosomiasis, but they demonstrated little selectivity over mammalian MRC5 cells in ...

Objective: Cervical cancer is the second most common cause of death from cancer in women throughout the world. The aim of this study was to evaluate the cytotoxic activity of Kelussia odoratissima (K. odoratissima) extract associated with radiotherapy in cervical cancer cells (HeLa cell line).Materials and Methods: Different concentration of the extract (25-500µg/ml) was tested in HeLa cell lin...

Conducting cell apoptosis pathways is a novel strategy in cancer treatment. This study aimed to explain that C. botrys essential oil could induce apoptosis and arrest the cell cycle in HeLa cells. Cytotoxic and apoptogenic effects of the essential oil of Jerusalem-oak (Chenopodium botrys L.), which was obtained from the aerial parts of the plant, were evaluated in HeLa cells. Cell viability was...

background: flavonoids have a variety of biological activities, such as anti-allergic, anti-inflammatory, anti-oxidative, free radical scavenging, and anti-mutagenic. methods: the cytotoxic effects of three synthesized flavonoid derivatives (k3, k4 and k5) were evaluated against hela , mda-mb -231 and ht-29 cancer cells using mtt assay. results: the results showed that these flavonoids were not...

Sulfonamides are the first effective chemotherapeutic agents used for several years to cure or prevent systemic bacterial infections. In addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the G1 phase, disruption of microtubule assembly, suppression of the transcription activator Nf-Y, angiogenesis and matrix metalloproteinase (MMP). In recent years, novel...

Two further attenuated measles virus vaccines, Sugiyama and Aik strains, developed in baby calf kidney cells and in Human Diploid Cells (MRC5) respectively were compared in a field trial. Both vaccines showed c1inical evidence of attenuation and both were highly immunogenic. Problems related to the success and failure of mass immunization against measles in developing countries and in hot c1ima...

Objective: Cervical cancer is the second most common type of cancer among women, worldwide; and for treatment of this type of cancer radiotherapy is commonly used. Ferula gummosa Boiss(“Barije” in Persian, from the family Apiaceae), (F. gummosa), is an extremely precious medicinal plant which naturally grows throughout the Mediterranean and Central Asia and is a native plant in Iran. The presen...

Background and Aim: Cervical and breast cancer are considered to be the most common cause of death among Iranian women. Various studies have shown that probiotics are effective fighting cancer. The aim of the present study was to investigate the effect of Lactobacillus brevis on apoptosis and casp (casp3, casp8) gene expression in HeLa cancer cells.  Materials and Methods: In this study, L. br...
