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).

TBE56 (0.05-5 μM, 5-16 h) induces HMOX1 mRNA expression, promotes BACH1 degradation, and reduces nuclear BACH1 levels in A549, H1299, MDA-MB-231, and MDA-MB-468 cells in a concentration-dependent manner[1].
TBE56 (100 nM, 6 h) reduces migration and invasion of wild-type MDA-MB-231 cells[1].
TBE56 (110 nM, 3 h pretreatment) significantly decreases intracellular Fe2+ accumulation and ROS generation in Prominin-2-overexpressed BMSCs[2].
TBE56 (110 nM, 3 h pretreatment) significantly increases GSH/GSSG ratio and decreases MDA content in Prominin-2-overexpressed BMSCs[2].
