Introduction: Over accumulation of polyamines is one of the causes of cancer because polyamines could promote the cancer cells growth. Due to the lack of specificity and increased reports of side effects in the current cancer treatment, one of the strategies to overcome the challenges is by utilizing polyamines as vectors of known cytotoxic compounds to target the cancer cells. Therefore, this study was aimed to investigate the cytotoxicity effect of Spermidine Sulphur Analogues Type 1 and Type 2 (SSA-1 and SSA-2) against human lung adenocarcinoma cells (A549), human colorectal adenocarcinoma cells (HCT-8) and human breast adenocarcinoma cell (MCF-7).  Materials and method: The cytotoxicity studies of SSA-1 and SSA-2 against in vitro cells: A549, HCT-8, and MCF-7 were carried out by using MTT assay and the IC50 in each cell was determined.  Results: SSA-1 exhibited cytotoxicity effect in all selected cell lines with IC50 between 2.0 mM to 5.3 mM. While SSA-2 also exhibited cytotoxicity effect in all cell lines with IC50 between 0.8 mM to 5.0 mM.  Conclusion: SSA-1 and SSA-2 were cytotoxic against A549, HCT-8, and MCF-7. However, the cytotoxic effect was not potent against these cell lines as a higher concentration of compounds was needed to inhibit the cells growth. Hence, it is suggested that further study on the cytotoxicity effect of SSA-1 and SSA-2 in other cell lines should be conducted and the formulation of the analogues based on sulphur should be amended by conjugating it with selected metal.

Introduction: Cancer is one of the global health problems that has a detrimental effect to a person's life. However, chemotherapeutic agents success are subject to the side effects due to lack of specificity in the drug delivery system to cancer cells and an increase risk of systemic toxicity to the normal cells. Polyamine transport system (PTS) is one of the potential pathways for transporting anticancer agent into specific cancer cells. This is due to the upregulation of PTS in cancer cells compared to normal cells for the proliferation activity. The aim of this study was to investigate the cytotoxicity effect of putrescine-sulphur analogues type 1 (PSA-1) and type 2 (PSA-2) on human lung adenocarcinoma cells (A549), human colorectal adenocarcinoma cells (HCT-8) and human breast adenocarcinoma cell (MCF-7). Materials and method: The cytotoxicity effect of newly synthesized PSA-1 and PSA-2 were evaluated on selected cancer cells; MCF-7, A549 and HCT-8 cell lines. The halfmaximal inhibitory concentration (IC50) obtained from tetrazolium bromide (MTT) assay was derived from the dose-response graph for all cell lines. Results: PSA-2 elicited cytotoxicity effect, eventhough the IC50 values were not potent with IC50 of 5.4 mM, 5.2 mM and 7.0 mM for MCF-7/48h, A549/48h and HCT-8/48h, respectively. The PSA-1 compound exhibited cytotoxicity effect in all cell lines, however, the compound failed to induce anti-proliferation at the concentration of 3 mM and above. The cytotoxicity of PSA-2 compound against MCF-7 cell lines showed higher potency compared to A549 and HCT-8 cell lines. Conclusion: It was suggested that PSA-2 compound was able to exert cytotoxicity effect against selected cancer cells, in low potency and is deemed for further investigation to increase its effectiveness against specific cancer cells.

Introduction: Breast cancer is one of the most prevalent malignancies among women. Patients whose suffering from this condition, as a result of the use of conventional therapies often have a poor response to treatment and the relapse among them is frequent. In this study, the effects of staphylococcal enterotoxin type B on BAK، FAS، BAX، TNF-a، BCL-2 و Survivin genes expression in human breast adenocarcinoma cells (MCF-7) was examined. Staphylococcal enterotoxin B is a powerful member of the Staphylococcus aureus toxins family, which is known as an anticancer agent with potential for killing cancer cells. Methods: The experimental study was carried out at the Biotechnology Research Center of Islamic Azad University, Shahrekord Branch. By using Lipofectamine 2000 reagent, MCF-7  cells transfected with the pcDNA3.1(+)-seb (recombinant) and  pcDNA3.1(+) (non-recombinant)  plasmids and were selected by culturing in a selective medium of RPMI- 1640 containing 600 μg / mL antibiotic G418. Then, the expression of BAK, FAS, BAX, TNF-a, BCL-2, and Survivin genes in transfected cells were analyzed by real time PCR. Student's t-test, SPSS Inc., Chicago, IL; Version 16 and also Excel program for statistical analysis were used. Results: The results of this study indicated that staphylococcal enterotoxin type B (SEB) remarkably changes the expression of apoptotic related genes in MCF-7 cell line. It was observed a significant increase in the expression of BAK, FAS, BAX, and TNF-a genes, the expression of BCL-2 and Survivin genes significantly decreased compared to the control group (P=0/032). Conclusion: Staphylococcal enterotoxin type B has an inhibitory effect on the growth, proliferation and invasion of breast adenocarcinoma cells through altering the expression of the genes involved in the apoptosis process. Therefore, it seems that there is a good research field for the use of this toxin in the control and treatment of human breast adenocarcinoma.

Sandalwood essential oil (SEO) is extracted fromSantalumtrees. Althoughα-santalol, a main constituent of SEO, has been studied as a chemopreventive agent, the genotoxic activity of the whole oil in human breast cell lines is still unknown. The main objective of this study was to assess the cytotoxic and genotoxic effects of SEO in breast adenocarcinoma (MCF-7) and nontumorigenic breast epithelial (MCF-10A) cells. Proteins associated with SEO genotoxicity were identified using a proteomics approach. Commercially available, high-purity, GC/MS characterized SEO was used to perform the experiments. The main constituents reported in the oil were (Z)-α-santalol (25.34%), (Z)-nuciferol (18.34%), (E)-β-santalol (10.97%), and (E)-nuciferol (10.46%). Upon exposure to SEO (2–8 μg/mL) for 24 hours, cell proliferation was determined by the MTT assay. Alkaline and neutral comet assays were used to assess genotoxicity. SEO exposure induced single- and double-strand breaks selectively in the DNA of MCF-7 cells. Quantitative LC/MS-based proteomics allowed identification of candidate proteins involved in this response: Ku70 (p=1.37E-2), Ku80 (p=5.8E-3), EPHX1 (p=3.3E-3), and 14-3-3ζ(p=4.0E-4). These results provide the first evidence that SEO is genotoxic and capable of inducing DNA single- and double-strand breaks in MCF-7 cells.

Rhodanine and its derivatives are not only valued for their interesting chemical properties but also present a wide range of bioactivities and their chemical and pharmacological applications have been investigated. From 3-methyl-4-thiorhodanine we synthesized S-acylated and C-acylated products using (some) carboxylic acid chlorides and the obtained products were studied the anti-proliferative activity by a SRB (sulforhodamine B) assay against a human breast cancer cell line. The results showed that C-acylated products are better inhibitors than S-acylated products.

Two new polyisoprenylated acylphloroglucinols, 7- epi-isoxanthochymol and 7- epi-cycloxanthochymol (1 – 2), were isolated from the barks of Garcinia nervosa together with their 7-epimers isoxanthochymol (3) and cycloxanthochymol (4). Their structures were determined on the basis of NMR spectroscopic data. The cytotoxic activity of the isolated compounds against HL-60, MCF-7 (human breast adenocarcinoma), A549 (human lung adenocarcinoma) and HepG2 (human hepatocellular carcinoma) cells were evaluated, and all compounds showed cytotoxic activity against all cell lines.
