Bucladesine calcium (Dibutyryl-cAMP calcium; DC2797 calcium salt) is a cell-permeable PKA activator/agonist and a cAMP analog that mimics the action of endogenous cAMP. It is a cyclic nucleotide derivative (structurally similar to cAMP) and is also a phosphodiesterase inhibitor. Dibutyryl-cAMPpreferentially activates cAMP-dependent protein kinase. The products releaes butyrate due to intracellular and extracellular esterase action. Butyrate was shown to have distinct biological effects. The compound is used in a wide variety of research applications because it mimics cAMP and can induce normal physiological responses when added to cells in experimental conditions.

Male rats were given either a bilateral infusion of 10 mM or 100 mM of bucladesine, and the results showed a significant reduction in escape latency and distance traveled (indicating improvement in spatial memory) when compared to controls. Male rats' ability to retain spatial memory is enhanced when they receive an infusion of 1 or 5 mM buclodesin minutes after receiving 0.5 mg of nicotine [1]. ChAT and VAChT immunoreactivity in the CA1 region rose significantly when Bucladesine (10 mM/side) and nicotine (0.5 mM/side) were combined. Additionally, there was a considerable increase in the optical density and quantity of ChAT and VAChT immunostaining with nicotine and low-dose Bucladesine therapy. decrease in the rats' escape delay and distance traveled [2]. Following the application of the aqueous solution to the skin-excision site, bucladesine is almost entirely absorbed very quickly. Bucladesine is absorbed more slowly but more quickly in the absence of skin peeling than in the full-thickness abrasion rat model [3]. In a mouse ear edema model caused by arachidonic acid, bucladesine (containing 1.5% emulsion for single or several injections) can considerably reduce inflammatory edema [4].

Solubility in Formulation 1: ≥ 2.5 mg/mL (5.12 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.12 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*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.
