General description

A cell-permeable benzothiazolyl-acetamide compound that inhibits the cellular Wnt processing and secretion via selective blockage of MBOAT (membrane-bound O-acyltranferase) family member Porcn- (Porcupine) mediated Wnt palmitoylation. IWP-2 does not affect Wnt/β-catenin signaling pathway in general and, unlike IWR-1-endo (Cat. No. 681669), displays no effect against Wnt-stimulated cellular responses. Also available as a 10 mM solution in DMSO (Cat. No. 506072).

The upregulation of spinal NMDA receptor is a crucial mechanism in remifentanil-induced hyperalgesia (RIH). Wnt3a/β-catenin pathway plays an important role in neuropathic pain. We hypothesized that wnt3a inhibitor (iwp-2) could downregulate the expression of NR2B subunit in NMDA receptor, in
