Lst-1 and / or compounds that are transported by the lst-2

摘要

PROBLEM TO BE SOLVED: To provide a new probe for cancer cell detection or hepatic cell detection and a medicament carrier comprising the compound and delivering a medicament to a cancer cell or a hepatic cell.SOLUTION: A new transport substrate for LST-1 as a transporter protein specifically expressing in a hepatic cell or for LST-2 as a transporter protein specifically expressing in a cancer cell is identified and the identified transport substrate of LST-1 and/or LST-2 is used as a probe for cancer cell detection or hepatic cell detection or a medicament carrier comprising the compound and delivering a medicament to a cancer cell or a hepatic cell.
