Compound class: Synthetic organic
Comment: RG-1530 is an orally active multikinase inhibitor, with a high affinity for polo like kinase 4 (PLK4). Its PLK4 inhibitory action was expoited for antiproliferative potential [1-4]. PLK4 is expressed at very low levels in normal cells, but its expression can be upregulated in cancer cells where it localises to the centriole and is essential for controlling centriole duplication and mitotic progression. This makes PLK4 an ideal target for disrupting mitosis in cancer cells.
