Abstract

Oral cancer, which affects the tongue and oral cavity, is a highly infectious disease incident in world population and can cause disability, facial deformities and death. The choice treatment is costly and usually involves the administration of chemotherapy, which may have cytotoxic action also on healthy cells, and numerous adverse reactions, such as fall and hair loss, sore in mouth, nausea, vomiting and pain which affect significantly the quality and survival of patients. Therefore, it becomes necessary to search for more functional, innovative and clinically viable treatments. In this context, the use of bioactive molecules, as peptide CTT1, proves to be an innovative alternative and effective because the CTT1 showed specificity for squamous cell carcinoma of the tongue, the most common form of oral cancer. However, the clinical use of peptides faces many challenges, mainly due to their physicochemical characteristics and low oral bioavailability, which involve the administration by the parenteral route. Using this route of administration can result in poor patient compliance to treatment due to the necessity of repeated injections, once the CTT1 have reduced half-life. Therefore, it becomes necessary to develop drug delivery systems clinically safe and appropriate to enable the use of peptides. The buccal administration of nanostructured liquid crystal precursors systems (CLPS) with mucoadhesive cationic polymer adjuvants emerges as a valuable strategy for administration CTT1, whereas the buccal mucosa has high permeability and high blood flow, which may enhance absorption of CTT1. Furthermore, the SPCL may enable the incorporation of CTT1 concomitant with the methylene blue (MB) photosensitizer allowing association of PDT with the peptide antitumor therapy, which may enhance the treatment of oral cancer. This project aims to develop a SPCL consisting of cetyl alcohol ethoxylated propoxylated 20 and 5, oleic acid and aqueous phase containing chitosan polymer dispersion with or without polyethyleneimine dispersion for buccal delivery of CTT1 peptide and AM and later investigate the in vitro and in vivo cytotoxic and photocytotoxic action of the formulations. Thus, we intend to develop a delivery system for nanostructural level for use in the treatment of oral cancer. (AU)
