NOTUM is a carboxylesterase that has been shown to act by mediating the O-depalmitoleoylation of Wnt proteins resulting in suppression of Wnt signaling. Here, we describe the development of NOTUM inhibitors that restore Wnt signaling for use in in vitro disease models where NOTUM over activity is an underlying cause. A crystallog. fragment screen with NOTUM identified 2-phenoxyacetamide 3 as binding in the palmitoleate pocket with modest inhibition activity (IC50 33 μM). Optimization of hit 3 by SAR studies guided by SBDD identified indazole 38 (IC50 0.032 μM) and isoquinoline 45 (IC50 0.085 μM) as potent inhibitors of NOTUM. The binding of 45 to NOTUM was rationalized through an X-ray co-crystal structure determination which showed a flipped binding orientation compared to 3. However, it was not possible to combine NOTUM inhibition activity with metabolic stability as the majority of the compounds tested were rapidly metabolized in an NADPH-independent manner. In the experiment, the researchers used many compounds, for example, Isoquinolin-7-amine (cas: 23707-37-1Synthetic Route of C9H8N2).
Isoquinolin-7-amine (cas: 23707-37-1) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines. They are also used to make oil-soluble dyes, food colorants, pharmaceuticals, pH indicators and other organic compounds. Synthetic Route of C9H8N2
