Research Abstract

Considering caffeine preventive effects on Parkinson's disease, we examined effects of caffeine analogues on PD cellular models via autophagic regulation using cellular models.
HeLa cells treated with a caffeine analogue have shown characteristics of autophagic inhibition via mTOR independent pathway, especially via cAMP. Also, one of them induced cell death in some cell lines but not in others. Taken together, some caffeine analogues might be potential candidates for anti-cancer agents.
