abstract = {Herein we present the rapid development of LH168, a potent
and highly selective chemical probe for WDR5, streamlined by
utilizing a DEL-ML (DNA encoded library-machine learning)
hit as the chemical starting point. LH168 was
comprehensively characterized in bioassays and demonstrated
potent in cellulo target engagement at the WIN-site pocket
of WDR5, with an EC50 of approximately 10 nM, a long
residence time, and exceptional proteome-wide selectivity
for WDR5. In addition, we present the X-ray co-crystal
structure and provide insights into the structure-activity
relationships (SAR). In parallel, we developed a matched
negative control compound as well as an alkyne analog
(compound 16) to facilitate the development of bifunctional
molecules. Taken together, we provide the scientific
community with a well-characterized chemical probe to enable
studies and functional manipulation of WDR5 in a cellular
context, as this protein represents a therapeutically
relevant target with scaffolding functions that influence
multiple cellular processes.},
