Anti-Inflammatory drugs have been routinely used in the management of acute and chronic inflammatory conditions. Nevertheless, their undesirable side and adverse effects have encouraged the development of more selective, tolerable and efficacious drugs able to modulate the inflammatory process through distinct mechanisms than those of drugs currently available in the market, for instance, inhibition of leukocyte recruitment (chemotaxis, rolling, adhesion and transmigration). Natural products, including Brazilian propolis, have been considered a rich source of anti-inflammatory molecules due to a very complex phytochemical diversity. Brazil has at least thirteen distinct types of propolis and many bioactive compounds have been isolated therefrom, such as apigenin, artepillin C, vestitol, neovestitol, among others. These molecules were proven to play a significant immunomodulatory role through (i) inhibition of inflammatory cytokines (e.g. TNF-alpha) and chemokines (CXCL1/KC and CXCL2/MIP2); (ii) inhibition of lam, ERK1/2, JNK and p38MAPK phosphorylation; (iii) inhibition of NF-kappa B activation; and (iv) inhibition of neutrophil adhesion and transmigration (1CAM-1, VCAM-1 and E-selectin expression). In this review, we shed light on the new advances in the research of compounds isolated from Brazilian propolis from Apis mellifera bees as potentially novel anti-inflammatory drugs. The compilation of data and insights presented herein may open further avenues for the pharmacological management of oral and systemic inflammatory conditions. Further research should focus on clinical and acute/chronic toxicological validation of the most promising compounds described in this review. (C) 2017 Elsevier Masson SAS. All rights reserved. (AU)
