				        	Objective To design and synthesize autophagic degraders targeting BRD4 based on autophagosome tethering compound (ATTEC) strategy and test their BRD4 degradation activity. Methods BRD4-targeting ATTECs were constructed by conjugating ispinesib that used as a LC3 ligand and JQ1 through a variety of alkane linkers. The final compounds were confirmed by 1H NMR, 13C NMR and ESI-MS, and their degradation activity in different cell lines were tested by Western Blot. Results Five BRD4-ATTEC molecules were successfully synthesized for the first time. Compound 4 showed moderate BRD4 degradation activity in different cell lines. Conclusion The novel BRD4 autophagic degraders were discovered, which expanded the applicability of targeted autophagic degradation via ATTEC.
