For last couple of decades, natural products have served us well in combating different types of cancer. The main sources of these useful compounds are from both animal and plant origin. Here we will present anticancer ability of bee venom (BV) and apigenin (API) towards different types of cancer cells in vitro. BV from honey bees is a complex mixture of a variety of different active peptides while API is a natural flavonoid found in several dietary plant foods. Anticancer effect of whole BV was tested in human cervical carcinoma HeLa cells and their drug-resistant HeLa CK subline while anticancer effect of API was tested in human breast cancer MCF-7 and MDA MB-231 cells. Cytotoxicity of both compounds towards cancer cells was evaluated by MTT assay whereas type of cell death was analysed by differential staining using acridine orange/ethidium bromide and was further verified by Western blot analysis. BV displayed dose-dependent cytotoxicity against both cell lines tested with drug-resistant HeLa CK cells being more sensitive to BV than their parental cell lines. Similarly, API inhibited the growth of both cell lines in a dose-dependent manner with MCF-7 cells being more sensitive. Treatment with BV induced a necrotic type of cell death, as shown by characteristic morphological features, fast staining with ethidium bromide and a lack of cleavage of apoptotic marker poly (ADP-ribose) polymerase (PARP) on Western blot. On the contrary, cell treated with API showed apoptosis as a dominant type of cell death in both cell lines which was further verified by Western blot analysis detecting cleaved PARP. In view of accumulating evidence on anti-proliferative and pro-cell death activity, both tested compounds could be used in the development of future anticancer drugs. Undoubtedly, therapeutic applications of BV and API are promising, however further in vitro and in vivo studies are warranted to resolve precise mechanisms responsible for their anticancer properties

Background: Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer deaths among Canadian women. Cancer management through changes in lifestyle, such as increased intake of foods rich in dietary flavonoids, have been shown to decrease the risk associated with breast, liver, colorectal, and upper-digestive cancers in epidemiologic studies. Onions are high in flavonoid content and one of the most common vegetables. Additionally, onions are used in most Canadian cuisines.Methods: We investigated the effect of five prominent Ontario grown onion (Stanley, Ruby Ring, LaSalle, Fortress, and Safrane) extracts on two subtypes of breast cancer cell lines: a triple negative breast cancer line MDA-MB-231 and an ER+ breast cancer line MCF-7.Results: These onion extracts elicited strong anti-proliferative, anti-migratory, and cytotoxic activities on both the cancer cell lines. Flavonoids present in these onion extracts induced apoptosis, cell cycle arrest in the G2/M phase, and a reduction in mitochondrial membrane potential at dose-dependent concentrations. Onion extracts were more effective against MDA-MB-231 compared to the MCF-7 cell line. Conclusion: In this study, we investigated the extracts synthesized from Ontario-grown onion varieties in inducing anti-migratory, cytostatic, and cytotoxic activities in two sub-types of human breast cancer cell lines. Anti-tumor activity of these extracts depends upon the varietal and can be formulated into nutraceuticals and functional foods for the wellbeing of cancer patients. Overall, the results suggest that onion extracts are a good source of flavonoids with anti-cancerous properties.Keywords: onion extracts; flavonoids; anti-proliferative; breast cancer; cytotoxic activity

Aim: This study aimed to explore an affordable technique for the fabrication of Chitosan Nanoshuttles (CSNS) at the ultrafine nanoscale less than 100 nm with improved physicochemical properties, and cytotoxicity on the MCF-7 cell line. Background: Despite several studies reported that the antitumor effect of CS and CSNS could achieve intracellular compartment target ability, no enough available about this issue and further studies are required to address this assumption. Objectives: The objective of the current study was to investigate the potential processing variables for the production of ultrafine CSNS (> 100 nm) using Box-Benhken Design factorial design (BBD). This was achieved through a study of the effects of processing factors, such as CS concentration, CS/TPP ratio, and pH of the CS solution, on PS, PDI, and ZP. Moreover, the obtained CSNS was evaluated for physicochemical characteristics, morphology Also, hemocompatibility, and cytotoxicity using Red Blood Cells (RBCs) and MCF-7 cell lines were investigated. Methods: Box-Benhken Design factorial design (BBD) was used in the analysis of different selected variables. The effects of CS concentration, sodium tripolyphosphate (TPP) ratio, and pH on particle size, Polydispersity Index (PDI), and Zeta Potential (ZP) were measured. Subsequently, the prepared CS nanoshuttles were exposed to stability studies, physicochemical characterization, hemocompatibility, and cytotoxicity using red blood cells and MCF-7 cell lines as surrogate models for in vivo study. Result: The present results revealed that the optimized CSNS have ultrafine nanosize, (78.3±0.22 nm), homogenous with PDI (0.131±0.11), and ZP (31.9±0.25 mV). Moreover, CSNS have a spherical shape, amorphous in structure, and physically stable. Also, CSNS has biological safety as indicated by a gentle effect on red blood cell hemolysis, besides, the obtained nanoshuttles decrease MCF-7 viability. Conclusion: The present findings concluded that the developed ultrafine CSNS has unique properties with enhanced cytotoxicity. thus promising for use in intracellular organelles drug delivery.

By keeping these things in mind we have designed and synthesized a new series of amide and sulfonamide coupled thiophene. A series of novel substituted 3-sulfamoylbenzo[b]thiophene-4- carboxamide molecules containing sulfonamide and amide group were designed, synthesized and used for anti-proliferative activity study. Methods: The final compounds 16-36 were synthesized by using series of reactions comprising sulfonation, sulfonamide coupling, hydrolysis and peptide coupling. The yields of compounds 16- 36 are in the range of 90-98%. The structures of the synthesized compounds were elucidated and confirmed by 1H NMR, 13C NMR, LCMS and the purity was checked through HPLC analysis. The compounds were further tested for their in vitro anticancer activity against a series of cell lines A549, HeLa, MCF-7 and Du-145. Results: The intermediates 8-13, 15 and final compounds 16-36 were synthesized in good yields. The synthesized compounds were further tested for their anticancer activity and most of compounds showed moderate to good anticancer activity against all four cell lines. Conclusion: We have synthesized 21 compounds and were screened for anticancer activity against MCF-7, HeLa, A-549 and Du-145 cancer cell lines. Most of the compounds were active for tested cell lines with IC50 value in the range of 1.81 to 9.73 μM. The compounds 18, 19, 21, 25, 30, 31 and 33 are most active in cell line data with IC50 value in the range of 1.81 to 2.52 μM.

Background: Target-based approach to drug discovery currently attracts a great deal of interest from medicinal chemists in anticancer drug discovery and development. Histone deacetylase (HDAC) inhibitors represent an extensive class of targeted anti-cancer agents. Among the most explored structure moieties, hydroxybenzamides and hydroxypropenamides have been demonstrated to have potential HDAC inhibitory effects. Several compounds of these structural classes have been approved for clinical uses to treat different types of cancer, such as vorinostat and belinostat. Aims: This study aims at developing novel HDAC inhibitors bearing conjugated quinazolinone scaffolds with potential cytotoxicity against different cancer cell lines. Method: A series of novel N-hydroxyheptanamides incorporating conjugated 6-hydroxy-2 methylquinazolin-4(3H)- ones (15a-l) was designed, synthesized and evaluated for HDAC inhibitory potency as well as cytotoxicity against three human cancer cell lines, including HepG-2, MCF-7 and SKLu-1. Molecular simulations were finally performed to gain more insight into the structure-activity. relationships. Results: It was found that among novel conjugated quinazolinone-based hydroxamic acids synthesized, compounds 15a, 15c and 15f were the most potent, both in terms of HDAC inhibition and cytotoxicity. Especially, compound 15f displayed up to nearly 4-fold more potent than SAHA (vorinostat) in terms of cytotoxicity against MCF-7 cell line with IC50 value of 1.86 µM, and HDAC inhibition with IC50 value of 6.36 µM. Docking experiments on HDAC2 isozyme showed that these compounds bound to HDAC2 with binding affinities ranging from -10.08 to -14.93 kcal/mol compared to SAHA (-15.84 kcal/mol). It was also found in this research that most of the target compounds seemed to be more cytotoxic toward SKLu-1than MCF-7 and HepG-2. Conclusion: The resesrch results suggest that some hydroxamic acids could emerge for further evaluation and the results are well served as basics for further design of more potent HDAC inhibitors and antitumor agents.

Background: Hybrid molecules furnished by merging two or more pharmacophores is an emerging concept in the field of medicinal chemistry and drug discovery. Currently, coumarin hybrids have attracted the keen attention of researchers to discover their therapeutic capability against cancer. Objective: The present study aimed to evaluate the in vitro antitumor activity of a new series of hybrid molecules containing coumarin and quinolinone moieties 4 and 5 against four cancer cell lines. Materials and Methods: A new series of hybrid molecules containing coumarin and quinolinone moieties, 4a-c and 5a-c, were synthesized and screened for their cytotoxicity against prostate PC-3, breast MCF-7, colon HCT- 116 and liver HepG2 cancer cell lines as well as normal breast Hs-371 T. Results: All the synthesized compounds were assessed for their in vitro antiproliferative activity against four cancer cell lines and several compounds were found to be active. Further in vitro cell cycle study of compounds 4a and 5a revealed MCF-7 cells arrest at G2 /M phase of the cell cycle profile and induction apoptosis at pre-G1 phase. The apoptosis-inducing activity was evidenced by up-regulation of Bax protein together with the downregulation of the expression of Bcl-2 protein. The mechanism of cytotoxic activity of compounds 4a and 5a correlated to its topoisomerase II inhibitory activity. Conclusion: Hybrid molecules containing coumarin and quinolinone moieties represents a scaffold for further optimization to obtain promising anticancer agents.
