TTA-A2
Based on 1 publication(s) in Google Scholar
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.

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].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (6.61 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Please enter the basic information of animal experiments:

-
Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:
-
%DMSO +
Recommended: Keep the proportion of DMSO in working solution below 2% if your animal is weak.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
