Biological Activity
PF-9363 (CTx-648) is a first-in-class potent and high selective KAT6A/KAT6B inhibitor. PF-9363 can be used for the research of cancer[1][2].
In Vitro
PF-9363 (0~1 μM; 1 day; ZR75-1, T47D and MCF7 cells) down-regulates the expression of H3K23Ac biomarker[1]. PF-9363 leads to down regulation of a specific set of genes involved in ESR1 pathway, cell cycle and stem cell pathways. PF-9363 shows that the IC50 values for ZR75-1 and T47D are 0.3 nM and 0.9 nM[1]. Western Blot Analysis[1] Cell Line: ZR75-1, T47D and MCF7 cells Concentration: 0~1 μM Incubation Time: 1 day Result: Down-regulated the expression of H3K23Ac biomarker.
In Vivo
PF-9363 shows strong anti-tumor activity in patient-derived xenograft models[1].
