OICR41114

OICR41114 (PROTAC4) is a PROTAC degrader targeting WDR5. It effectively degrades endogenous WDR5 with an EC50 of 40 nM and a Dmax of 49%. The degradation of HiBiT-tagged WDR5 by OICR41114 occurs in a proteasome-dependent manner. This compound is composed of a target protein ligand, Dimethyl-F-OICR-9429-COOH, an E3 ligase ligand, OICR-8268-acrylic acid, and a PROTAC linker, Amino-PEG9-amine. Notably, the conjugate of the E3 ligase ligand and the linker is OICR-8268-acrylic acid-amino-PEG9-amine.
