PROTACs Targeting MLKL Protect Cells from Necroptosis

Rathje, Oliver H. ; Perryman, Lara ; Payne, Richard J. ; Hamprecht, Dieter W. ;

DOI: 10.1021/acs.jmedchem.3c00665 PubMed ID: 37535857 JMC,2023,66(16):11216-11236.

Abstract: Mixed Lineage Kinase domain-Like pseudokinase (MLKL) is implicated in a broad range of diseases due to its role as the ultimate effector of necroptosis and has therefore emerged as an attractive drug target. Here, we describe the development of PROteolysis TArgeting Chimeras (PROTACs) as a novel approach to knock down MLKL through chem. means. A series of candidate degraders were synthesized from a high-affinity pyrazole carboxamide-based MLKL ligand leading to the identification of a PROTAC mol. that effectively degraded MLKL and completely abrogated cell death in a TSZ model of necroptosis. By leveraging the innate ability of these PROTACs to degrade MLKL in a dose-dependent manner, the quant. relationship between MLKL levels and necroptosis was interrogated. This work demonstrates the feasibility of targeting MLKL using a PROTAC approach and provides a powerful tool to further our understanding of the role of MLKL within the necroptotic pathway.

		A solution of tert-butyl 4- (3-METHOXY-3-OXOPROPYL) PIPERIDINE-1-CARBOXYLATE (2.0 g, 7.37 mmol) in 8 ml of methanol was added a solution of LIOH monohydrate (0.46g, 11.0 mmol) in 2 ml of water. The resulting solution was stirred at rt for 16h and it was concentrated under vacuum. To the residue was added 0.35 ml of acetic acid and 0.1 ml of water. The mixture was poured into a solution of EtOAc and CH2CL2 (1 : 1). The organic layer was dried with NA2SO4, filtered through celite and concentrated. To give 1.6g of 3- [1- (tert-butoxycarbonyl) piperidin-4- yl] propanoic acid.
