RN-9893 (hydrochloride)

Description: RN-9893 is an antagonist of transient receptor potential vanilloid 4 (TRPV4, IC50s = 0.42 and 0.66 µM, respectively, for the human and rat receptors).1 It is selective for TRPV4 over TRPV1, TRPV3, and TRPM8 (IC50s = 10, >30, and 30 µM, respectively). RN-9893 reduces rat TRPV4 activity induced by 4alpha-phorbol 12,13-didecanoate or hypotonicity (IC50s = 0.57 and 2.1 µM, respectively, in cell free assays). Target: Others. Smiles: Cl.O=C(NC1=CC=C(C=C1)S(=O)(=O)N2CCN(CC2)C(C)C)C3=CC=C(C=C3N(=O)=O)C(F)(F)F. References: Wei, Z.L., Nguyen, M.T., O'Mahony, D.J., et al.
