Description: ABC99 is a Selective Irreversible Inhibitors of the Wnt-Deacylating Enzyme, ABC99 inhibited NOTUM with an IC50 value of 13 nM and showed excellent selectivity across the serine hydrolase family, as initially assessed by gel-based ABPP of soluble and membrane proteomes from SW620 cells. ABC99 preserves Wnt-mediated cell signaling in the presence of NOTUM and was also converted into an ABPP probe for visualizing NOTUM in native biological systems.

Additional Information

Wnt proteins are secreted morphogens that play critical roles in embryonic development and tissue remodeling in adult organisms. Aberrant Wnt signaling contributes to diseases such as cancer. Wnts are modified by an unusual O-fatty acylation event (O-linked palmitoleoylation
of a conserved serine) that is required for binding to Frizzled receptors. O-Palmitoleoylation of Wnts is introduced by the porcupine (PORCN) acyltransferase and removed by the
serine hydrolase NOTUM. PORCN inhibitors are under development for oncology, while NOTUM inhibitors have potential for treating degenerative diseases
