Biochem/physiol Actions

ABC99 is an N-hydroxyhydantoin (NHH) carbamate-based irreversible, potent and selective inhibitor against the serine hydrolase activity of the Wnt-deacylating enzyme NOTUM (IC50 = 13 nM against NOTUM-mediated labeling of fluorophosphonate (FP) probe), an enzyme that reverses the posttranslational O-linked palmitoleate modification of Wnt proteins. ABC99 prevents NOTUM-mediated negative regulation against Wnt3A-dependent cellular signaling (EC50 = 89 nM by HEK293T TOPflash reporter assay) with excellent selectivity over 65 other serine hydrolases, including PPT1.
Inhibition of NOTUM has therapeutic use in treating degenerative diseases including osteopenia and osteoporosis.[1]
Irreversible, potent and selective inhibitor against NOTUM serine hydrolase activity and sustanins Wnt3A-dependent signaling in the presence of NOTUM.

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

Remodeling of the uterine vasculature by invasive extravillous trophoblasts (EVTs) is a critical aspect of human placentation. Insufficient EVT invasion can lead to severe obstetrical complications like preeclampsia, intrauterine growth restriction, and preterm birth. Glial cells missing-1 (GCM1) is a
