Inhibitory effect of cycloartenol ferulate, a component of rice bran, on tumor promotion in two-stage carcinogenesis in mouse skin

Article abstract of DOI:10.1248/bpb.21.1072

Inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate (TPA)- induced inflammation in mice was observed in the methanol extract of rice bran and γ-oryzanol. The active components of rice bran, sitosterol ferulate, 24-methylcholesterol ferulate, cycloartenol ferulate and 24- methylenecycloartanol ferulate inhibited markedly the TPA-induced inflammation in mice. The 50% inhibitory dose of these compounds for TPA- induced inflammation was 0.2-0.3 mg/ear. Furthermore, cycloartenol ferulate markedly inhibited the tumor-promoting effect of TPA in 7,12- dimethylbenz[α]lanthracene-initiated mice.
