Chemical Name: O-[(5-Amino-2-phenyl-7-benzoxazolyl)methyl]-3,5-dichloro-L-tyrosine dihydrochloride
Biological ActivityKYT 0353 is a potent and selective inhibitor of L-type amino acid transporter 1 (LAT1) (IC50 = 60 nM for 14C-leucine uptake in H-29 cells). Also suppreses 14C-leucine uptake in renal proximal tubule cells expressing LAT1 (IC50 = 140 nM). Displays ~500-fold selectivity for LAT1 over LAT2. Reduces cell viability and induces apoptosis in YD-38 oral cancer cells. Arrests growth in several tumor cell lines. Exhibits growth inhibitory effects on HT-29 cells in vivo.
