PRKD inhibitor CRT0066101 exhibits anti-TNBC effects via modulating a phosphor-signaling network and inhibiting the phosphorylation of many cancer-driving factors, including MYC, MAPK1/3, AKT, YAP, and CDC2, providing insight into the important roles as well as the molecular mechanism of CRT0066101 as an effective drug for TNBC.
The Discovery of a Dual TTK Protein Kinase/CDC2-Like Kinase (CLK2) Inhibitor for the Treatment of Triple Negative Breast Cancer Initiated from a Phenotypic Screen.
In vitro studies showed that treatment of triple negative breast cancer (TNBC) MDA-MB-231 cells with Se-PFPs (1) inhibited cell growth dose-dependently by arresting cells at G2 phase via inhibiting CDC25C-CyclinB1/CDC2 pathway; (2) caused apoptosis associated with increased p53, Bax, Puma and Noxa, decreased Bcl2, increased Bax/Bcl2 ratio and increased activities of caspases 3/9, suggesting its effect on p53-mediated cytochrome c-caspase pathway.
