Cell growth inhibitor

The present invention revealed that AT-264 suppresses cell growth through its inhibitory effect on PepT1 activity. Furthermore, as a result of examining whether AT-264 comprises the effect of inhibiting the cell growth of human pancreatic cancer cell line AsPC-1, the present invention revealed that cell growth is similarly suppressed. These findings show that cell growth can be suppressed by inhibiting the activity of peptide transporters. Suppression of peptide transporter activity can be considered to be an important indicator in the development of growth inhibitors for cancer cells and such.
