| Description | MN58b is a selective inhibitor of choline kinase α (CHKα). |
| In vitro | MN58b (1-5 μM; 72 hours; SK-PC-1, Suit2 008, IMIM-PC2, and RWP-1 cells) has a marked effect on colony formation at 1 μM, and growth is completely abolished at 5 μM in all the cell lines[1] |
| In vivo | MN58b treatment significantly decreases phosphomonoesters in both HT29 and MDA-MB-231 xenografts. Phosphocholine levels are found to correlate with choline kinase activities[2]. |
