Application

PF-06658607 has been used to evaluate the proteome-wide selectivity of covalent kinase inhibitors.

Biochem/physiol Actions

PF-06658607 is an alkynylated irreversible Brutons tyrosine kinase (BTK) inhibitor that covalently reacts with active-site cysteine residues in the ATP binding pocket. PF-06658607 has been used as a probe for proteomic analysis to identify off-target binding substrates. The alkyne moiety allows for addition of an azide-based detection probe via copper-catalyzed click chemistry methods.

Cravatt Group – Professor Product Portal

The aim of the Cravatt research group is to understand the roles that mammalian enzymes play in physiological and pathological processes and to use this knowledge to identify novel therapeutic targets for the treatment of human disease. To achieve these goals, they develop and apply new technologies that bridge the fields of chemistry and biology, ascribing to the philosophy that the most significant biomedical problems require creative multidisciplinary approaches for their solution. The group's technological innovations address fundamental challenges in systems biology that are beyond the scope of contemporary methods. For instance, enzymes are tightly regulated by post-translational events in vivo, meaning that their activity may not correlate with expression as measured by standard genomic and proteomic approaches. Considering that it is an enzyme's activity, rather than abundance that ultimately dictates its role in cell physiology and pathology, the Cravatt group has introduced a set of proteomic technologies that directly measures this parameter. These activity-based protein profiling (ABPP) methods exploit the power of chemistry to engender new tools and assays for the global analysis of enzyme activities. The enzyme activity profiles generated by ABPP constitute unique molecular portraits of cells and tissues that illuminate how metabolic and signaling networks are regulated in vivo. Additionally, by evaluating enzymes based on functional properties rather than mere abundance, ABPP acquires high-content proteomic information that is enriched in novel markers and targets for the diagnosis and treatment of human disease.
