PPZ2

PPZ2 is a diacylglycerol (DAG) -activated TRPC3/TRPC6/TRPC7 channel activator with activity in promoting neuronal development and survival. PPZ2 activates recombinant TRPC3/TRPC6/TRPC7 channels in a dose-dependent manner without affecting other TRPC channels. PPZ2 elicits cation currents and calcium ion (Ca (2+) ) influx in cultured central neurons. PPZ2 is able to induce BDNF-like neurite outgrowth and neuroprotection, an effect that disappears after TRPC3/TRPC6/TRPC7 knockdown or inhibition. PPZ2 also increases the activation of the calcium-dependent transcription factor cAMP response element binding protein. The effects of PPZ2 suggest that calcium signaling mediated by activation of DAG-activated TRPC channels plays an important role in its neurotrophic effects[1].
