Alda-1 is a potent and selective Aldehyde Dehydrogenase-2 Agonist. Alda-1 reverses alcohol-induced hepatic steatosis and cell death in mice. Alda-1 inhibits atherosclerosis and attenuates hepatic steatosis in apolipoprotein E-knockout mice. Alda-1 reduces cerebral ischemia/reperfusion injury in rat through clearance of reactive aldehydes. Pharmacological activation of ALDH2 by Alda-1 reversed alcoholic steatosis and apoptosis through accelerating aldehyde clearance. This study indicates that ALDH2 is a promising molecular target and Alda-1 has therapeutic potential for treating alcoholic liver disease.

Alda-1 therapy resulted in a considerable decrease in 4-HNE protein concentration in the plasma of apoE−/− animals. Alda-1 injection resulted in a small increase in the expression of genes associated to neurogenesis (Nog), mitochondrial biogenesis (CYTB, ND1), and apoptosis (Bax, Gsk3b) in Hp of apoE−/− mice. Alda-1 treatment resulted in the synthesis of 2 and 10 differently expressed proteins in FCx and Hp, respectively, of apoE−/− mice [1]. Alda-1 (1.5 mg/kg, bw, IP) injection significantly increased climbing time in prenatally stressed rats in the forced swim test, tending to decrease immobility time and increase swimming time. Furthermore, treatment of prenatally stressed rats with Alda-1 dramatically enhanced the number of entry into the open arms of the labyrinth and the duration spent in the maze, as determined by the elevated plus maze test [2]. After 24 hours of glucose administration, Alda-1 (8.5 mg/kg; intraperitoneal injection) and glucose dramatically reduced the number of 4-HNE and FJB-positive cells in the cerebral cortex of Alda-1-treated rats, which was significantly lower than that of DMSO-treated rats. [3]. Alda-1 (10 mg/kg per day) therapy avoids aldehyde excess, mitochondrial dysfunction and improves cardiac function in animals with post-MI cardiomyopathy [4].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.71 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 2: 24 mg/mL (74.04 mM) in 0.5% CMC-Na/saline water (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
