The non-peptide neuroprotective agents SR 57746A interacts with neurotrophin 3 to induce differentiation in the PC12 cell-line.


PMID 9600726

Abstract

SR 57746A (1-(2beta-naphthylethyl)-4-(3-trifluoromethylphenyl)-1,2,5,6 -tetrahydropyridine hydrochloride) is a neuroprotective compound which potentiates nerve-growth factor (NGF)-induced differentiation in PC12 cells. We have evaluated the interaction of SR 57746A with the other members of the neurotrophin family in this cell-line. In contrast with NGF, neurotrophin-3 did not increase the differentiation of PC12 cells. However, the association of SR 57746A with neurotrophin-3 significantly increased neurite outgrowth. No significant activity on neurite outgrowth was observed with brain-derived neurotrophic factor or neurotrophin-4, either alone or combined with SR 57746A. These results indicate that as well as potentiating the effect of NGF SR 57746A enables neurotrophin-3, which alone is inactive, to increase the differentiation of these cells.
