Abstract

The wound healing involves the integration of biological and molecular events and in case of chronic wounds can involve the use of drugs that are associated with unwanted side effects. Thus, there is a search by alternatives therapeutics that are less toxic, for example, natural products. The use of natural compounds is an attractive approach to treating inflammatory disorders, wounds and burns. In this context thymol is a promising compound for use in wound healing and inflammatory process due to its properties such as antimicrobial, antioxidant and antiseptic. However essential oils and their constituents, as thymol, exhibit high volatility and can also easily decompose. Thereby the encapsulation of these compounds into nanoparticles is a viable and efficient strategy to modulate the release of the active ingredient to increase the physical stability, decrease its volatility and reduce the toxicity. Thus, the aim of this project is the encapsulation of thymol in nanoparticles composed of natural lipids to increase its penetration into the skin and protect it against degradation. The carrier containing thymol will be produced by emulsion and sonication method and will be evaluated the deformation capacity of the developed nanoparticle. In addition, in vivo studies in mice will be done to investigate the antioxidant and anti-inflammatory activities of the nanoparticles containing thymol. (AU)
