Abstract

Official abstract text for this publication.

A method for sorting pluripotent cells using a compound which is eliminated from the pluripotent cells through the MDR1 transporter.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of sorting non-differentiated pluripotent cells from differentiated somatic cells the method comprising: (i) contacting sample cells with a compound which is eliminated from the pluripotent cells through the cellular MDR1 transporter, wherein the sample cells are pluripotent cells induced to differentiate to somatic cells and, wherein the compound has a structure of the formula (I): wherein R 1 is selected from the group consisting of the formula (II), (III) and (IV): wherein R 5 , R 6 , R 7 , R 8 and R 9 are respectively selected from the group consisting of hydrogen, halogen, C1 to C6 alkyl, phenyl, —OR 10 and —SR 10 , wherein R 10 is C1 to C6 alkyl or aryl, wherein R 2 , R 3 and R 4 are respectively selected from the group consisting of hydrogen, C1 to C6 alkyl and —(CH2) bill NR 11 R 12 , and m is an integer of 1 to 12; and R 11 and R 12 are respectively selected from the group consisting of hydrogen, C1 to C6 alkyl and chloroacetyl, or R 2 , and R 3 form the cyclic conformation of the formula (V) together with the nitrogen atom to which R, and R3 are bound: wherein 1 is an integer of 1 to 6, and X is selected from the group consisting of O, S, NH and NR 13 , wherein R 13 is C1 to C6 alky; and wherein the sample cells which have accumulated the compound are the non-differentiated pluripotent cells (ii) detecting and sorting the cells the non-differentiated pluripotent cells. 2. The method of claim 1 , wherein: R 2 and R 3 are respectively selected from the group consisting of hydrogen, methyl, ethyl, dimethylaminoethyl and 10-chloroacethylaminodecyl or R 2 and R 3 form the cyclic conformation of 1-piperidinyl; R 4 is methyl; R 5 is selected from the group consisting of hydrogen, fluorine, methoxy, phenoxy, methylthio, methyl, propyl and phenyl; R 6 and R 7 are respectively selected from the group consisting of hydrogen, fluorine, chlorine, methoxy and methyl; R 8 is fluorine; R 9 is methoxy; and X is selected from the group consisting of O, S and methylamino. 3. The method of claim 2 , wherein the compound is selected from the group consisting of the compounds shown in Table 1 below: TABLE 1
