MedKoo CAT#: 408112

CAS#: 203192-01-2 (bromide)

Description: MN58b is a selective choline kinase α (CHKα) inhibitor. MN58b is a novel anticancer drug that inhibits choline kinase, resulting in inhibition of phosphocholine synthesis. Inhibition of choline kinase by MN58b resulted in altered phospholipid metabolism both in cultured tumor cells and in vivo.
