A Phytochemicals Approach Towards the Treatment of Cervical Cancer Using Polyphenols and Flavonoids.

AIM: Despite enormous progress in cancer biology, oncologists are still struggling to retrieve the methods and drugs to cure cancer which remains a global threat to humans. Plant-derived natural compounds, also known as phytochemicals, carry therapeutic potential and could be taken as dietary supplements, which are a radical way to resist as well as cure cancer. The present study reveals the anti-cancerous potential of a few phytochemical constituents under in vitro conditions and their mode of action on cervical cancer. SiHa was treated with phytochemicals viz. Quercetin dihydrate, Gallic Acid, and Naringin with varying concentrations to assess their cytotoxicity potential by various methods and also to elucidate their IC50 values. METHODS: All three compounds reduced the cell number and viability, along with alterations in cancer cell morphology. The diagnosed IC50 values of the compounds were 160µM, 200µM, and 1500µM for Quercetin dihydrate, Gallic Acid, and Naringin, respectively. DNA fragmentation assay and gene expression analysis were also used to assess apoptosis and anti-proliferative activity of compounds. RESULTS: We found fragmented DNA in treated cells as assessed by gel electrophoresis assay. These phytochemicals elicit an apoptotic response in SiHa cells by significantly up-regulating the gene expression level of p53 and p21 (p-value <0.005). CONCLUSION: Considering the anti-cancer and anti-proliferative potential of Quercetin dihydrate, Gallic Acid, and Naringin on the cervical cancer cell line, these phytochemicals could be used as an alternative or concurrent cancer therapeutic approach. However, further in-depth elucidation of their mode of action, safety, and efficacy should be explored.

Bioactive compounds and their libraries: An insight into prospective phytotherapeutics approach for oral mucocutaneous cancers.

Oral mucocutaneous cancers (OMCs) are cancers that affect both the oral mucosa and perioral cutaneous structures. Common OMCs are squamous cell carcinoma (SCC), basal cell carcinoma (BCC) and malignant melanoma (MM). Anatomical similarities and conventions which categorizes these lesions blur the magnitude of OMCs in diverse populations. The burden of OMC is high in the sub-Saharan Africa and Indian subcontinents, and the cost of management is prohibitive in the resource-limited, developing world. Hence, there is a pressing demand for the use of cost-effective in silico approaches to identify diagnostic tools and treatment targets for diseases with high burdens in these regions. Due to their ubiquitousness and accessibility, the use of therapeutic efficacy of plant bioactive compounds in the management of OMC is both appropriate and plausible. Furthermore, screening known mechanistic disease targets with well annotated plant bioactive compound libraries is poised to improve the routine management of OMCs provided that the requisite access to database resources are available and accessible. Using natural products minimizes the side effects and morbidities associated with conventional therapies. The development of innovative treatments approaches would tremendously benefit the African and Indian populace and reduce the mortalities associated with OMCs in the developing world. Hence, we discuss herein, the potential benefits, opportunities and challenges of using bioactive compound libraries in the management of OMCs.
