Background

Curcumin (CAS 458-37-7) is a natural small molecule known to inhibit tyrosinase activity, with an IC50 of 47 μM. It modulates multiple signaling pathways involved in tumorigenesis and inflammation, influencing transcription factors, growth factors, cytokines, receptors, and enzymes. Clinical trials at Phase I reported no observed toxicity at doses up to 12 g/day; however, oral bioavailability is limited (~1% in Phase I/II studies). Additionally, curcumin demonstrates potential for Alzheimer's research, as evidenced by reducing beta-amyloid (Aβ40, Aβ42) production via downregulating presenilin-1 and GSK-3β in SH-SY5Y neuroblastoma cells.

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.
