Abstract:
:A new series of Proteolysis Targeting Chimeras (PROTACs) targeting Bruton's Tyrosine Kinase (BTK) was synthesized, with the goal of improving the pharmacokinetic properties of our previously reported PROTAC, MT802. We recently described the ability of MT802 to induce degradation of both wild-type and C481S mutant BTK in immortalized cells and patient-derived B-lymphocytes. However, the pharmacokinetic properties of MT802 were not suitable for further in vivo development. Therefore, we undertook a systematic medicinal chemistry campaign to overcome this issue and made a series of PROTACs with structural modifications to the linker and E3-recruiting ligand; more specifically, the new PROTACs were synthesized with different von Hippel-Lindau (VHL) and cereblon (CRBN) ligands while keeping the BTK ligand and linker length constant. This approach resulted in an equally potent PROTAC, SJF620, with a significantly better pharmacokinetic profile than MT802. This compound may hold promise for further in vivo exploration of BTK degradation.
