Did you miss Ulrich Luecking’s talk about "Sulfoximines in Medicinal Chemistry: Unlocking Novel Opportunities in Drug Design"?

In this Flash Talk, Ulrich Luecking, VP and Head of Chemistry at FoRx Therapeutics, explores the untapped potential of sulfoximines in modern drug discovery. He highlights several exciting development candidates on novel and established targets such as AZ's ATR inhibitor ceralasertib, Artios' ATR inhibitor ART0380, Tango's CoREST complex inhibitor TNG-260, and many more. Ulrich also showcases the use of sulfoximines beyond traditional small molecules and exemplifies innovative synthetic strategies for accessing them.

A standout moment in the talk was the first time disclosure of FORX-1589, a covalent WRN inhibitor featuring a novel vinyl sulfoximine warhead. The patent application containing this compound was just published last week.

The Flash Talk concluded with a lively Q&A where Ulrich answered many insightful audience questions. Watch the full Flash Talk on our YouTube channel now and don't forget to share it with a colleague who'd appreciate knowing more about the use of sulfoximines as an innovative functional group!
