For example, one of these inhibitors, JPH203 KYT-03533), sinhibitedthe inhibited the growth of human colon cancer cells in vitro and in vivo 18, and 2-aminobicyclo- 2,2,1 -heptane-2-carboxylic acid, a second inhibitor, reduced the viability of lung cancer cells 19, suggesting that LAT1 inhibitors may be clinically useful as cancer chemotherapy.
