Crizotinib 0-10 hyperpolarization-activated, cyclic nucleotide-gated K+ 4 Mus musculus 20-81 28217366-7 2017 Crizotinib resulted in diminished current density of HCN4, the major molecular determinant of If, with an IC50 of 1.4 +- 0.3 mumol/L. Crizotinib 0-10 hyperpolarization-activated, cyclic nucleotide-gated K+ 4 Mus musculus 53-57 28217366-8 2017 Crizotinib also slowed HCN4 activation and shifted the activation curve to the left towards more hyperpolarized potentials. Crizotinib 0-10 hyperpolarization-activated, cyclic nucleotide-gated K+ 4 Mus musculus 23-27 28217366-9 2017 CONCLUSIONS: Our results suggest that crizotinib"s effects on HCN4 channels play a significant role in mediating its observed effects on HR. Crizotinib 38-48 hyperpolarization-activated, cyclic nucleotide-gated K+ 4 Mus musculus 62-66
