ABSTRACT
α-zingiberene is a phytochemical of the sesquiterpenes class, the major constituent of the essential oil from the leaves of Casearia sylvestris, a plant widely used in traditional medicine for the treatment of inflammatory diseases, tumours, and bacterial infections. In the present study, we evaluated the effects of daily administration of α-zingiberene (0.01, 0.1 and 1 µg diluted in 10 µl of 0.5% DMSO) on the inflammatory, angiogenic, and fibrogenic components, induced by subcutaneous sponge implants in an animal model. Treatment with sesquiterpene resulted in a reduction in macrophage activation, as well as in mean blood vessels and in the activity of metalloproteinases 2 and 9. Furthermore, it resulted in an increase in collagen deposition near the implants. These results show the therapeutic potential of α-zingiberene in the treatment of pathologies, in which processes such as inflammation and angiogenesis are exacerbated, or even for the treatment of chronic wounds.
