JPH203(also known as KYT-0353) is a potent and selective LAT1 selective ( L-type amino acid transporter 1) inhibitor. JPH203 can very potently inhibit l-leucine uptake. JPH203 inhibits YD-38 cell growth. JPH203 up-regulated the population of apoptotic YD-38 cells through the activation of apoptotic factors, including caspases and PARP.
