| Description | 1. Pinostilbene has protective effects against 6-hydroxydopamine-induced neurotoxicity in SH-SY5Y cells, it can reduce release of lactate dehydrogenase and activity of caspase-3 triggered by 6-hydroxydopamine (6-OHDA) in a dose-dependent manner. 2. Pinostilbene can significantly inhibit the growth of human colon cancer cells, i.e., HCT116 and HT29, 20 and 40 uM of pinostilbene causes cell cycle arrest at S phase and induces apoptosis in colon cancer cells. |

Protective effects of pinostilbene, a resveratrol methylated derivative, against 6-hydroxydopamine-induced neurotoxicity in SH-SY5Y cells.[Pubmed:19443200]
J Nutr Biochem. 2010 Jun;21(6):482-9.
Resveratrol (3,4',5-trans-trihydroxystilbene) is a phytoalexin with emerging lines of evidence supporting its beneficial effects on cardiovascular systems and inhibition of carcinogenesis. It has also been reported that certain methylated resveratrol derivatives are more effective than resveratrol in the prevention/treatment of cancer. However, little is known about the impact of resveratrol and its derivatives on the development of Parkinson's disease. In this study, we compared the neuroprotective effects of resveratrol with four methylated (fully or partially) resveratrol derivatives against parkinsonian mimetic 6-hydroxydopamine (6-OHDA)-induced neurotoxicity in SH-SY5Y cells. Release of lactate dehydrogenase and activity of caspase-3 triggered by 6-OHDA were significantly reduced by resveratrol and one of the methylated derivatives, Pinostilbene (3,4'-dihydroxy-5-methoxystilbene), in a dose-dependent manner. In addition, Pinostilbene exerted a potent neuroprotective effect with a wider effective concentration range than resveratrol. By using high-performance liquid chromatography, we found that uptake of Pinostilbene into SH-SY5Y cells was significantly higher than that of resveratrol. Enhanced bioavailability may thus be a major factor contributing to the neuroprotective activity of Pinostilbene. Moreover, Western blot analysis demonstrated that Pinostilbene markedly attenuated the phosphorylation of JNK and c-Jun triggered by 6-OHDA. Besides, mammalian target of rapamycin kinase may be an intracellular target accounting for the neuroprotective effects of Pinostilbene. Our findings demonstrate the potential of methylated stilbenes in neuroprotection and provide important information for further research in this field.
