Camphorataimide B (CamB) has anticancer activities against several tumors. Here, we aimed to investigate the mechanism(s) by which CamB inhibits metastasis of colorectal cancer (CRC) cells. Low-dose CamB did not affect the cell viability and cell cycle progression of CRC cells, but significantly inhibited the metastatic potentials of CRC cells. Mechanically, CamB reduced the protein and mRNA expression of BMP4, and inhibited Smad and FAK/Src/Akt signaling. CamB also decreased Snail levels by promoting its degradation via proteasome and thereafter reduced Snail-mediated BMP4 transcription. Moreover, CamB considerably inhibited the in vivo metastasis of DLD-1 cells in xenograft mice.
