XUN49524 also known as Vezf1-IN-T4, is an inhibitor of the pro-angiogenic activity of the zinc finger transcription factor Vezf1. XUN49524 was first reported in Molecules (2018), 23(7), 1615 1-1615 15 . This product has no formal name at the moment. For the convenience of communication, a temporal code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https: www.medkoo.com page naming).
FmocNH-PEG4-t-butyl ester is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
Tos-PEG4-t-butyl ester (Tos-PEG4-Boc) is a PROTAC linker characterized by its PEG composition. This compound plays a crucial role in the synthesis of a range of PROTACs, including BI-3663, a highly selective PTK2 FAK PROTAC. It employs cereblon ligands to target E3 ligases for the degradation of PTK2, exhibiting potent inhibitory activity with an IC50 of 18 nM[1].
