Selective degradation-inducing probes for studying cereblon (CRBN) biology.

ABSTRACT: Targeted protein degradation represents a rapidly growing area in drug discovery and development. Moreover, small molecules that induce the targeted degradation of a given protein also represent an important addition to the chemical probes toolbox as these compounds can achieve selective protein knockdown, thus providing an approach that is orthogonal to genetic knockdowns. In order to develop degradation-inducing chemical probes for studying cereblon (CRBN) biology, we generated six CRBN-CRBN (homo-PROTAC) degraders and six CRBN-VHL (hetero-PROTAC) degraders. From these compounds we identified two potent and selective CRBN degraders (ZXH-4-130 and ZXH-4-137), both of which are CRBN-VHL compounds. We characterized these lead degraders by quantitative proteomics in five cell l
