Background

Curcumin is an inhibitor of tyrosinase with IC50 value of 47uM [1].

Curcumin is a natural compound with potency of anticancer. It is currently under clinical investigation for cancer chemoprevention. There is a variety of biochemical mechanisms of this anticancer function. The targets of Curcumin are involved in signaling pathways include transcription factors, growth factors,

inflammatory cytokines, receptors, and enzymes. Phase I trials have tested the toxicity and tolerability of Curcumin and found that Curcumin has no toxicities at doses up to 12 g/day. However, the bioavailability of Curcumin is quite poor. It is about ~1% after oral administration in phase I/II clinical trials and this hinders Curcumin‘s use in the clinic [2].

It is also reported that Curcumin reduces the generation of amloid beta (Aβ 40 and Aβ42) in SH-SY5Y neuroblastoma cells. It also down-regulates the expression of PS1 and GSK-3β in cells. All these cause the inhibition of Aβ formation and make Curcumin to be a potent therapeutic agent in AD [3].
