vu-f14480

LAS195319 is a potent and selective inhaled PI3Kδ Inhibitor (IC50 = 0.5 nM) for the Treatment of Respiratory Diseases.

VUF14480 is a covalent partial agonist that interacts with cysteine 98(3.36) of the human histamine H₄ receptor. VUF14480 was shown to be a partial agonist of hH4 receptor-mediated G protein signalling and β-arrestin2 recruitment. VUF14480 bound covalently to the hH₄ receptor with submicromolar affinity. Serine substitution of C98(3.36) prevented this covalent interaction.
