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].

Protocol

Cell experiment:[1]
Cell lines	B16-R melanoma cells resistant to doxorubicin
Reaction Conditions	1 ~ 200 μM curcumin for 24, 36 or 48 h incubation
Applications	Curcumin was found to be cytotoxic in vitro for B16-R melanoma cells resistant to doxorubicin either cultivated as monolayers (1 ~ 100 μM) or grown in three-dimensional cultures (1 ~ 200 μM). The cytotoxic effect observed in the 2 culture types was related to the induction of programmed cell death.
Animal experiment:[1]
Animal models	Female B6D2F1 mice (6 ~ 8 weeks old) challenged subcutaneously with B16-R melanoma cells
Dosage form	25 mg/kg Once daily by intraperitoneal injection
Applications	The combination treatment consisting of curcumin and soluble B16-R proteins resulted in substantial inhibition of growth of B16-R melanoma, whereas each treatment by itself showed little effect. Moreover, animals receiving the combination therapy exhibited an enhancement of their humoral anti-soluble B16-R protein immune response and a significant increase in their median survival time. Therefore, curcumin may provide a valuable tool for the development of a therapeutic combination against the melanoma.
