RP-1664
Based on 1 Customer Validation
RP-1664 is a selective and orally active PLK4 inhibitor with an IC50 of 3 nM. RP-1664 demonstrates exquisite selectivity over related kinases, including AURKA/B and PLK1. RP-1664 disrupts centriole biogenesis in cancer cells and leads an accumulation of PLK4 and p21 protein. RP-1664 demonstrates increased sensitivity in TRIM37-high-expressing cells or tumors. RP-1664 exhibits anti-tumor activity in breast cancer and neuroblastoma research[1][2].

RP-1664 (1-1000 nM, 48-72 h) increases total PLK4 protein levels in RPE1-hTERT Cas9 TP53-null cells and increases p21 protein levels in RPE1-hTERT Cas9 TP53-WT cells dose dependently[1]. RP-1664 (0.001-10 μM) demonstrates a ~30-fold increase in sensitivity between TRIM37-normal/TP53-KO cells and TRIM37-overexpressing/TP53-WT cells, with intermediate sensitivity observed in TRIM37-high/TP53-KO and TRIM37-normal/TP53-WT cells[1]. RP-1664 (50-250 nM) induces centrosome loss at concentrations >100 nM in both p53-proficient and -deficient RPE1 cells as well as in three different NBL cell lines (CHP134, CHP212, SHSY5Y)[1]. RP-1664 (50-250 nM) induces supernumerary centrosomes between 25-100 nM in both p53-proficient and -deficient RPE1 cells[1]. RP-1664 (0-2000 nM, 48 h) enhances cellular sensitivity to PLK4 inhibition and centrosome depletion in a manner dependent on high TRIM37 protein levels and functional p53[1]. RP-1664 (compound 37) shows an EC50 of 0.051 μM in reducing MCF7 cell viability[2].
