Compound class: Synthetic organic
Comment: MS132 is a von Hippel-Lindau (VHL)-recruiting WDR5 PROTAC degrader [1]. It induces the formation of the WDR5-MS132-VCB (E3 ubiquitin ligase) ternary complex which promotes WDR5 proteasomal degradation. In pancreatic cancer cells, reduction of WDR5 protein disrupts its interactions with partner oncoproteins in its role as a core chromatin-regulatory scaffolding protein, and this produces an antiproliferative effect in these cells.
