Reactivation of the wild-type p53 pathway is one key goal aimed at developing targeted therapeutics in the cancer research field. Although most p53 protein kinases form 'p53-activating' signals, there are few kinases whose action can contribute to the inhibition of p53, as Casein kinase 1 (CK1) and Checkpoint kinase 1 (CHK1). Here we report on a pyrazolo-pyridine analogue showing activity against both CK1 and CHK1 kinases that lead to p53 pathway stabilisation, thus having pharmacological similarities to the p53-activator Nutlin-3. These data demonstrate the emerging potential utility of multivalent kinase inhibitors.
