Preparation

Pterostilbene was synthesized from 3,5-dimethoxybenzyl bromide and p-nitrobenzaldehyde by Witting-Hornor reaction, reduction, diazotization and hydrolysis, with a total yield of 53.9%.

benefits

Pterostilbene is a naturally-derived stilbenoid structurally related to resveratrol, with potential antioxidant, anti-inflammatory, pro-apoptotic, antineoplastic and cytoprotective activities. Pterostilbene is known to have many pharmacological benefits for the prevention and treatment of a wide variety of diseases, including ( cancer (McCormack and McFadden 2012), dyslipidaemia (Rimando et al. 2005), diabetes (Amarnath Satheesh and Pari 2006), cardiovascular degeneration (Amarnath Satheesh and Pari 2008) and pain (Hougee et al. 2005).

Biological Activity

A cell-permeable methoxylated analog of Resveratrol that displays antioxidant, anti-proliferative, and hypoglycemic properties. Appears to be a better free radical scavenger than Trolox. Moderately inhibits COX-1 & COX-2 activities (IC50 = 19.8 μM & 83.9 μM, respectively) and induces apoptosis in HL60 cells (IC50 = 70 μM). Also prevents DMBA-induced pre-neoplastic lesions (ED50 = 4.8 μM). Reported to decrease plasma glucose levels in streptozotocin-induced diabetic rats comparable to that of Metformin.

Definition

ChEBI: Pterostilbene is a stilbenol that consists of trans-stilbene bearing a hydroxy group at position 4 as well as two methoxy substituents at positions 3' and 5'. It has a role as an antioxidant, an antineoplastic agent, a neurotransmitter, a plant metabolite, an apoptosis inducer, a neuroprotective agent, an anti-inflammatory agent, a radical scavenger and a hypoglycemic agent. It is a stilbenol, a member of methoxybenzenes and a diether. It derives from a hydride of a trans-stilbene.
