Page/Page column 25; 26, (2021/08/27)
The present invention refers to a process for the selective modification of tyrosine units in a peptide sequence, in particular, by incorporating acyl groups in the ortho position of the hydroxyl residue of its aromatic ring. Likewise, the invention also

Aminopeptidase N (APN/CD13) is one of the essential proteins for tumour invasion, angiogenesis and metastasis as it is over-expressed on the surface of different tumour cells. Based on our previous work that L-isoserine dipeptide derivatives were potent APN inhibitors, we designed and synthesized L-isoserine tripeptide derivatives as APN inhibitors. Among these compounds, one compound 16l (IC50=2.51±0.2 M) showed similar inhibitory effect compared with control compound Bestatin (IC50=6.25±0.4 M) and it could be used as novel lead compound for the APN inhibitors development as anticancer agents in the future.
