摘要

By replacing the phosphate group in pTyr with an isoxazole carboxylic acid, a novel unnatural amino acid has been successfully synthesized. Subsequently, its incorporation into a known PPI (protein-protein interaction) inhibitor of STAT3 protein (ISS 610) generated I2 which showed reasonable anti-STAT3 activity in both fluorescence polarization and cell-proliferation experiments.
