Experimental evidence suggests that tyrosol [2-(4-hydroxyphenyl)ethanol] exhibits potent protective activities against several pathogeneses. In this study, we evaluated the protective effect of tyrosol against 1-methyl-4-phenylpyridinium (MPP(+))-induced CATH.a neuron cell death. Tyrosol dose-dependently protected CATH.a cells from MPP(+)-induced cell death and
