Panaxynol, a polyacetylene ((3R)-heptadeca-1,9-diene-4,6-diyn-3-ol; syn. falcarinol), was isolated from the lipophilic fractions of Panax notoginseng, a Chinese traditional medicinal plant. In the present study, we reported the neurotrophic effects of panaxynol on PC12D cells and mechanism involved in neurite outgrowth of the cells. Panaxynol could morphologically promote neurite outgrowth in PC12D cells, concentration-dependently reduce cell division and up-regulate molecular marker (MAP1B) expression in PC12D cells. Panaxynol induces the elevation of intracellular cAMP in PC12D cells. The neurite outgrowth in PC12D cells induced by panaxynol could be inhibited by the protein kinase A inhibitor RpcAMPS and by MAP kinase kinase 1/2 inhibitor U0126. These observations reveal that panaxynol could induce the differentiation of PC12D cells in a process similar to but distinct from that of NGF and the panaxynol's effects were via cAMP- and MAP kinase-dependent mechanisms.
