Cat.No. 6642 - QWF | Boc-Gln-D-Trp(Formyl)-Phe-OBzl | CAS No. 126088-82-2
Description: MRGPRX2 antagonist; also NK1 receptor antagonist
Literature (3)

Biological Activity

Tripeptide substance P (SP) antagonist (IC50 = 90 μM). Also inhibits binding of SP to Mas-related GPCR (MRGPR) X2. Inhibits SP-induced IgE-independent degranulation of mast cells in vitro. Inhibits compound 48/80-induced MRGPRX2 activation and scratching in mice in vivo.

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
