The research group specializes in Polo-like kinases (PLK) – a family of serine/threonine enzymes playing a critical role in the regulation of mitosis – and the inhibition of these. In a series of studies they have described the stereoselective synthesis of (1R,2S)-2-(1H-indazol-6-yl)spiro[cyclopropane-1,3′-indolin]-2′-ones as PLK4 Inhibitors, and now report one of these as a novel clinical candidate for cancer therapy.
Microwave reactions were performed on a Biotage® Initiator+ microwave synthesizer, and subsequent purification of intermediates and final products on an Isolera™ One flash purification system with Biotage® SNAP KP-Sil flash cartridges.
