Espindolol (AGI-001) is a novel and potent β-adrenoceptor antagonist with the potential to be used for the treatment of cachexia related to cancer.
| ln Vitro |
l-Pindolol (1 nM-100 μM) reduces the supermaximal CA1 pyramidal cells caused by 100 nM 5-CT with an IC50 value of 92 nM [1]. l-Pindolol (500 nM and 1 μM) blocks 5-toluidine tryptamine (5-CT; 10 nM) and 5-hydroxyamine tryptamine (5-HT; 15 μM) by detecting 5-CT and 5-HT on CA1 pyramidal cells. With an IC50 value of 522 nM, l-Pindolol (1 nM-100 μM) suppresses the supraminimal proliferation of CA3 neurons generated by 300 nM 5-CT[1].

|---|---|
| ln Vivo |
In brain regions where 5-HT1A receptors are present, [3H]-WAY 100635 accumulation was decreased by l-pindolol (15 mg/kg; i.p., repaired prior to [3H]-WAY 100635 injection).
|
| Animal Protocol |
Animal/Disease Models: Male Sprague Dawley rat [1]
Doses: 15 mg/kg Route of Administration: intraperitoneal (ip) injection; [3H]-WAY 100635 15 mg/kg before injection, 20 minutes acute treatment or 24 hrs (hrs (hours)), 16 hrs (hrs (hours)) and 20 minutes Short-term treatment Experimental Results: [3H]-WAY 100635 accumulation was diminished in brain regions containing 5-HT1A receptors, but had no effect on the dorsal raphe nucleus (DRN), hippocampal CA1 and CA3 regions. |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.07 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 (10.07 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. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.4027 mL | 2.0135 mL | 4.0271 mL |
*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.
