Cj. Stankovic et al., THE ROLE OF 4-PHOSPHONODIFLUOROMETHYL-PHENYLALANINE AND 4-PHOSPHONO-PHENYLALANINE IN THE SELECTIVITY AND CELLULAR UPTAKE OF SH2 DOMAIN LIGANDS, Bioorganic & medicinal chemistry letters, 7(14), 1997, pp. 1909-1914
Incorporation of 4-phosphonodifluoromethyl-phenylalanine (F(2)Pmp) and
4-phosphono-phenylalanine into SH2 targeted peptides and peptidomimet
ic ligands was found to effect binding affinity and selectivity of the
se ligands toward the Src and Abl SH2 domains. Furthermore, dipeptide
analogs containing these phosphonate amino acids were used to produce
prodrugs with excellent cellular delivery and reconversion rates. (C)
