Biological Activity

A-803467 is a potent and selective Nav1.8 sodium channel blocker. A-803467 blocks Nav1.8 in both half-maximal inactive and resting states with an IC50 of 8 nM and IC50 of 79 nM, respectively. A-803467 is >100-fold selective vs. human Na(v)1.2, Na(v)1.3, Na(v)1.5, and Na(v)1.7 (IC50 values >or=1 microM). Administration of A-803467 (10-30 mg/kg i.v.) reduced mechanically evoked (10-g von Frey hair) and spontaneous WDR neuronal activity in SNL rats. A-803467 also dose-dependently reduced mechanical allodynia in a variety of rat pain models. A-803467 is the first small-molecule blocker of sodium channels which showing both high potency and significant subtype-selectivity among the sodium channel family.

Customer Product Validations & Biological Datas
Source Sci Rep (2017). Figure 6. A-803467
Method Measurement of LSG function
Cell Lines Left stellate ganglion
Concentrations 20 mM
Incubation Time -
Results As shown in Fig. 6A, the ganglion neurons in the DMSO group were mostly stained positive for TH (red) and negative for TUNEL (green). However, in the high-concentration A-803467 treatment group, most ganglion neurons stained positive for both TH and TUNEL.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
