Brazilian Green Propolis artepillin C and its acetylated derivative activate the NGF-signaling pathways and induce neurite outgrowth in NGF-deprived PC12 cells

Chem Biodivers. 2023 Nov 12:e202301294. doi: 10.1002/cbdv.202301294. Online ahead of print.ABSTRACTArtepillin C is the most studied compound in Brazilian Green Propolis and, along with its acetylated derivative, displays neurotrophic activity on PC12 cells. Specific inhibitors of the trkA receptor (K252a), PI3K/Akt (LY294002), and MAPK/ERK (U0126) signaling pathways were used to investigate the neurotrophic mechanism. The expression of proteins involved in axonal and synaptic plasticity (GAP-43 and Synapsin I) was assessed by western blotting. Additionally, physicochemical properties, pharmacokinetics, and drug-likeness were evaluated by the SwissADME web tool. Both compounds induced neurite outgrowth by activating the NGF-signaling pathways but through different neuronal proteins. Furthermore, in silico analyses showed interesting physicochemical and pharmacokinetic properties of these compounds. Therefore, these compounds could play an important role in axonal and synaptic plasticity and should be further investigated.PMID:37953436 | DOI:10.1002/cbdv.202301294
