Protective effects of phytochemical antioxidants against neurotoxin-induced degeneration of dopaminergic neurons.

abstract：:We recently developed a novel cognitive enhancer, ST101 (spiro[imidazo[1,2-a]pyridine-3,2-indan]-2(3H)-one), that activates T-type voltage-gated calcium channels (VGCCs). Here, we address whether T-type VGCC activation with ST101 mediates its cognitive effects in vivo and the relevance of T-type VGCC activation to ace...
