(1S,2S,3R)-PLX-4545

(1S,2S,3R)-PLX-4545 is the (1S,2S,3R) enantiomer of PLX-4545 (HY-159647). PLX-4545 is an orally active and selective cereblon-based molecular glue degrader of IKZF2 (zinc finger transcription factor Helios). PLX-4545 can reprogram immunosuppressive regulatory T cells into pro-inflammatory effector T cells, thereby enhancing anti-tumor immune responses.
