(DMT1) have been identified that selectively target CSC by blockinglysosomalirontranslocation. This leads to lysosomaliron accumulation, production of reactive oxygen species and cell death with features of ferroptosis. DMT1inhibitors selectively target CSC in primary cancercells and circulating tumor cells, demonstrating the physiological relevance of this strategy. Taken together, this opens up opportunities

Three distinct series of substituted pyrazole blockers of divalent metal transporter 1 (DMT1) were elaborated from the high-throughput screening pyrazolone hit 1. Preliminary hit-to-lead efforts revealed a preference for electron-withdrawing substituents in the 4-amido-5-hydroxypyrazole series 6a-l. In turn, this preference was more pronounced in a series of 4-aryl-5-hydroxypyrazoles 8a-j. The representative analogs 6f and 12f were found to be efficacious in a rodent model of acute iron hyperabsorption. These three series represent promising starting points for lead optimization efforts aimed at the discovery of DMT1 blockers as iron overload therapeutics. (C) 2011 Elsevier Ltd. All rights reserved.
