AUTOphagy-TArgeting Chimeras

AUTOphagy-TArgeting Chimera (AUTOTAC) employs bifunctional molecules composed of target-binding ligands linked to autophagy-targeting ligands. AUTOTACs bind the ZZ domain of the otherwise dormant autophagy receptor p62/Sequestosome-1/SQSTM1, which is activated into oligomeric bodies in complex with targets for their sequestration and degradation.

ATC-324
ATC-324 is an bivalent AR (Androgen Receptor) degrader based on the protein degradation technology platform AUTOphagy-TArgeting Chimera (AUTOTAC). ATC-324 induces the formation of AR/p62 complex, leading to autophagy-lysosomal degradation of AR. ATC-324 can reduce nuclear AR levels and downregulate target gene expression of AR and AR-v7, and also has a degradation effect on common AR mutants in PCa. ATC-324 is composed of target-binding ligand (TBL) Enzalutamide (HY-70002) and p62/SQSTM1 autophagy-targeting ligand (ATL) YT 6-2 analog-1 (HY-169386), connected by Boc-NH-PEG4-CH2CH2NH2 (HY-W008352). Among them, the active control of the target protein ligand is Enzalutamide carboxylic acid (HY-70002B), and the conjugate composed of the autophagy-targeting ligand and the linker is YT 6-2-PEG3-C2-NH2 (HY-169387).
