2G-HaloAUTAC (Compound tt44) is a second-generation autophagy-targeting chimera(2G-HaloAUTAC) that improves the activity of AUTACs by replacing the L-Cysteine (L-Cys) linker with other structures. 2G-HaloAUTAC exhibits degradation activity against EGFP-HaloTag protein through an autophagic mechanism.
