    The protein kinase MKK7 is linked to neuronal development and the onset of cancer. The field, however, lacks high-quality functional probes that would allow for the dissection of its detailed functions. Against this background, we describe an effective covalent inhibitor of MKK7 based on the pyrazolopyrimidine scaffold.
