Description

Monascin is a kind of azaphilonoid pigments extracted from Monascus pilosus-fermented rice (red-mold rice). Monascin also exhibits anti-tumor-initiating activity and anti-inflammatory activity with oral administration. Monascin inhibits the activation of NOR 1 (an NO donor)[1][2].

In Vivo

Monascin (0.0025% in drinking water; mice) appears effective for the inhibition of UVB-initiated carcinogenesis on mouse skin[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: SENCAR mouse using a UVB irradiation as an initiator and TPA as a promoter[1].
Dosage: 0.0025% in drinking water.
Administration: Orally daily for 2 weeks in drinking water.
Result: Reduced the number of the papillomas.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
