ppm1d

CCT007093 is an effective PPM1D (WIP1) inhibitor (IC50: 8.4 μM).

BRD6257 is an orally active inhibitor of protein phosphatase 1D (proteinphosphatase, Mg2+ Mn2+ dependent 1D, PPM1D) with an IC50 of 5 nM. It activates the p53 signaling pathway (EC50 of 51 nM), enhances p21 expression, and inhibits the proliferation of cancer cells MOLM13 (IC50 = 2.8 μM). BRD6257 demonstrates good metabolic stability in human and rat liver microsomes.

SPI-001 is a selective inhibitor of PPM1D (IC50=0.48 µM) that exhibits anticancer activity. The compound inhibits the phosphatase activity of PPM1D in human breast cancer cells overexpressing PPM1D and enhances the phosphorylation of p53. Additionally, SPI-001 suppresses cell proliferation by inducing apoptosis.
