Nav1.5 Inhibitor

Nav1.5 Inhibitors (7):

Cat. No. Product Name Effect Purity
  • HY-17429
    Flecainide acetate
    Inhibitor 98.98%
    Flecainide acetate (R-818) is a class 1C antiarrhythmic agent especially used for the management of supraventricular arrhythmia; works by blocking the Nav1.5 sodium channel in the heart, causing prolongation of the cardiac action potential.
  • HY-16787
    ICA-121431
    Inhibitor 98.65%
    ICA-121431 is a nanomolar potent and broad-spectrum voltage-gated sodium channel (Nav) blocker, shows equipotent selectivity for human Nav1.1 and Nav1.3 subtypes with IC50 values of 13 nM and 23 nM, respectively. ICA-121431 shows less potent inhibition of Nav1.2 (IC50=240 nM) and 1,000 fold selectivity against Nav1.4, Nav1.6, and the TTX-resistant human Nav1.5 and Nav1.8 channels (IC50s >10 μM).
  • HY-139081
    GDC-0310
    Inhibitor 99.80%
    GDC-0310 is a selective acyl-sulfonamide Nav1.7 inhibitor, with an IC50 of 0.6 nM for hNav1.7.
  • HY-107405
    TC-N 1752
    Inhibitor 99.18%
    TC-N 1752 is a potent and orally active inhibitor of Nav1.7, with IC50s of 0.17 μM, 0.3 μM, 0.4 μM, 1.1 μM and 2.2 μM at hNav1.7, hNav1.3, hNav1.4, hNaV1.5 and rNav1.8, respectively. TC-N 1752 also inhibits tetrodotoxin-sensitive sodium channels. TC-N 1752 shows analgesic efficacy in the Formalin model of pain.
  • HY-P1218
    Phrixotoxin 3
    Inhibitor
    Phrixotoxin 3 is a potent blocker of voltage-gated sodium channels, with IC50s of 0.6, 42, 72, 288, 610 nM for NaV1.2, NaV1.3, NaV1.4, NaV1.1 and NaV1.5, respectively. Phrixotoxin 3 modulates voltage-gated sodium channels with properties similar to those of typical gating-modifier toxins, both by causing a depolarizing shift in gating kinetics and by blocking the inward component of the sodium current.
  • HY-120774
    GS-462808
    Inhibitor
    GS-462808 is an oral active late sodium current inhibitor (Late INai) of the cardiac Nav1.5 channel with the IC50 of 1.33 μM. GS-462808 can be used for study of arrhythmia.
  • HY-P5811
    Ceratotoxin-1
    Inhibitor
    Ceratotoxin-1 (CcoTx1), a peptide toxin, is an voltage-gated sodium channel subtypes inhibitor. Ceratotoxin-1 inhibits Nav1.1/β1, Nav1.2/β1, Nav1.4/β1, and Nav1.5/β1 with IC50 of 523 nM, 3 nM, 888 nM, and 323 nM, respectively. Ceratotoxin-1 also inhibits Nav1.8/β1.
