TBE56
TBE56, a molecular glue, is a BACH1 degrader, with an EC50 of 44 nM. TBE56 is a weak NRF2 inducer and the biotinylated TBE31. TBE56 interacts and promotes the degradation of BACH1 via a mechanism involving the E3 ligase FBX022. TBE56 reduces intracellular Fe2+ accumulation, ROS generation, and malondialdehyde (MDA) content, while increasing GSH/GSSG ratio and upregulating GPX4 in Prominin-2-overexpressed BMSCs. TBE56 significantly ameliorates intervertebral disc degeneration (IVDD) in puncture-induced SD rat IVDD model. TBE56 can be used for the study of intervertebral disc degeneration (IVDD).
