Synthesis and biological evaluation of (E)-4-(3-arylvinyl-1H-indazol-6-yl)pyrimidin-2-amine derivatives as PLK4 inhibitors for the treatment of breast cancer
a scaffoldhoppingstrategy. SAR exploration and preliminary assessment identified 14i as a new PLK4 inhibitor which displayed excellent potency in vitro. 14i could inhibit the activity of PLK4, perturb centriole replication, result in mitosis disorder and induce cell apoptosis in breast cancer cells. Moreover 14i demonstrated significant antitumor efficacy in the MDA-MB-468 and MDA-MB-231 xenograft
Disclosed are compounds of Formula (I), methods of using the compounds for inhibiting HPK1 activity and pharmaceutical compositions comprising such compounds. The compounds are useful in treating, preventing or ameliorating diseases or disorders associated with HPK1 activity such as cancer.

two stereogenic centers. This work reports the discovery of a novel one-pot double SN2 displacement reaction for the stereoselective installation of the desired asymmetric centers and confirms the stereochemistry of the most potent stereoisomer, e.g., 44. Subsequent work keys on the optimization of the oral exposure of nanomolar PLK4 inhibitors with potent cancer cell growth inhibitory activity. A short
