p1946

P-1946 is an HIV-1 protease inhibitor.

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

QWF acetate is a Substance P antagonist that specifically inhibits the binding of Substance P to its receptor (NK1) with an IC50 of 0.09 Μm; it can also inhibit the activation of Mas-related G-protein-coupled receptor X2 (MRGPRX2), which inhibits degranulation of mast cells.QWF acetate is used as a polypeptide in pain, inflammation and allergic reactions, QWF acetate has important applications as a peptide in the study of pain, inflammation and allergic reactions.
