Description: GlyH-101 is a CFTR inhibitor (cystic fibrosis transmembrane conductance regulator). GlyH-101 is a glycine hydrazide that has been shown to block CFTR channels. GlyH-101 blocked I(Cl.PKA) in a concentration- and voltage-dependent fashion (IC(50) at +100 mV=0.3 ± 1.5 μM and at -100 mV=5.1 ± 1.3 μM). GlyH-101 blocks the open pore of cardiac CFTR channels at an electrical distance of 0.15 ± 0.03 from the external membrane surface.
