Biological Activity
| ln Vitro | Atrial potential PRR is induced in isolated coronary vascular access by AZD-1305 (1,3 μM) [1]. In isolated coronary vascular access, atrial potential PRR is conducted by AZD-1305 (1,3 μM) [1]. Greater use-induced declines are produced by the maximal rising velocity of the beat (Vmax) [1]. 1-10 μM) significantly reduces Vmax, action potential triggering and onset potential of canine pulmonary vein cuff preparations; the action potential duration increases significantly at 90% repolarization. AZD-1305 (1,3 μM) induces sodium channel-mediated parameters in atrial coronary myocardial conduction compared to the ventricle. AZD-1305 (5 μM) tonicizes and modifies ventricular sodium channels in isolated coronary vascular access. Stronger blockade of ventricular sodium channels [1] AZD-1305 (and greater increase in diastolic excitation threshold [1]. Amiodarone greatly strengthened the action of AZD-1305, and AZD-1305 (1-10 μM) canine pulmonary vein catheter dramatically extended the basal cycle duration of the pulmonary vein cuff preparation while maintaining a 1:1 activator [2]. |
| ln Vivo | AZD-1305 (braid concentration 1.2 μM and 4.5 μM, intravenous infusion) has longer ERP prolongation duration and repolarization time than the ventricles of Beagle dogs [1]. Comparing the short-term duration and excitability of canine atria with Beagle canine ventricles, AZD-1305 (braid concentration 1.2 μM and 4.5 μM, intravenous administration) is more effective [1]. In the Beagle canine model of atrial fibrillation mediated by guinea choline, AZD-1305 (mid-mid 1-3 μM, intravenous infusion) stops persistent atrial fibrillation and inhibits its formation [1]. |

| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
