Anti-tumor application of 3-{2-[([1,1'-biphenyl]-4-methyl)amino]-1-ethoxy}phenol

The invention discloses an anti-tumor application of 3-{2-[([1,1'-biphenyl]-4-methyl)amino]-1-ethoxy}phenol. The 3-{2-[([1,1'-biphenyl]-4-methyl)amino]-1-ethoxy}phenol low molecular weight compound is screened out through a candidate medicine screening platform combining structural biology, bioinformatics and biology activity testing and can be applied to the anti-tumor field, or is combined with other medicines or means so as to be applied to the anti-tumor field. The 3-{2-[([1,1'-biphenyl]-4-methyl)amino]-1-ethoxy}phenol can be used for the targeted inhibition of HAb18G/CD147 protein and can be applied in the preparation of medicines for treating diseases related to HAb18G/CD147 protein high expression (such as tumors, especially liver cancer).
