Description of TTA-A2

TTA-A2 is a potent, selective and orally active t-type voltage gated calcium channel antagonist with reduced pregnane X receptor (PXR) activation. TTA-A2 is equally potent against the Cav3.1 (a1G) and Cav3.2 (a1H) channels with IC50 values of 89 nM and 92 nM, respectively, at -80 and -100 mV holding potentials. TTA-A2 can be used for the research of a variety of human neurological diseases, including sleep disorders and epilepsy[1][2].

TTA-A2 exhibits a state-dependent inhibition of α1I with potencies of 98 nM and 3.7 μM at membrane holding potentials of -80 and -100 mV, respectively in astandard voltage-clamp electrophysiology assay. It also exhibits excellent selectivity against the Cav1.2 (L-type), Cav2.1 (P/Q-type), Cav2.2 (N-type), and Cav2.3 (R-type) channels which all had IC50 values of >30 μM at 80 mV[1].TTA-A2 exhibits high affinity in the α1I binding assay with a Ki of 1.2 nM and has excellent selectivity over the hERG potassium channel and L-type calcium channel (both IC50>10 μM)[1].

TTA-A2 (oral gavage; 3 mg/kg; single dose) produces significant changes in sleep architecture in rats. A reduction in active wake soon after dosing with a concurrent increase in delta sleep and decrease in REM sleep. Additionally, these effects persists for up to 4 h post-dose in rats[1].TTA-A2 (oral gavage; 10 mg/kg; once daily; 5 days) shows selective effect on recurrent thalamocortical network activity, it suppresses active wake and promotes slow-wave sleep in wild-type mice but not in mice lacking both Cav3.1 and Cav3.3[2]. Animal Model: Wild-type and double Cav3.1/Cav3.3 knockout C57BL6/Sv129 background mices[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
