生物活性
Tephrosin 是一種天然類胡蘿卜素，具有較強(qiáng)的抗腫瘤活性。Tephrosin 通過誘導(dǎo)受體內(nèi)化來誘導(dǎo) EGFR 和 ErbB2 的降解。體外研究
Treatment of HT-29 cells with tephrosin (0-10μM) inhibits both the ligand-induced and constitutive phosphorylation of EGFR, ErbB2 and ErbB3, and concomitantly suppresses the activation of the downstream signaling molecules such as Akt and Erk1/2 mitogen-activated protein kinase (MAPK) .
