Taspoglutide (ITM-077; ITM077; ITM 077) is a novel, potent, and long-acting agonist of glucagon-like peptide 1 (GLP-1) receptor (EC50= 0.06 nM) with the potential to be used for treatment of type 2 diabetes.
| ln Vitro |
Taspoglutide (R1583/BIM51077) is a long-acting 10% formulation of (Aib8-35) human GLP-1 (7-36 amides) having 93% similarity to the original peptide. It activates GLP-1 receptors. Tasglutide has comparable affinity (affinity constant 1.1±0.2 nM) to the endogenous ligand of hGLP-1 receptor (affinity constant 1.5±0.3 nM) and demonstrates equal effectiveness in inducing cAMP generation [2].

| ln Vivo |
In isolated, cultured rat islets and perfused ZDF rat pancreas, taslutide has been demonstrated to accelerate the rate of glucose-induced insulin secretion. In Sprague-Dawley rats and diabetic db/db mice, taslutide demonstrates dose-related augmentation of glucose-dependent insulin release, which lowers blood glucose in the db/db animal model of type 2 diabetes [3]. During oGTT, acute tasglutide administration decreases glycemic swings and raises insulin responses. During the oGTT on day 21, there was a significant reduction in glucose excursions, GIP, PYY, and lipid levels in rats receiving continuous treatment [4]. Following tasglutide treatment, the liver's hepatic triglyceride levels were much lower. Taslutide did not lessen the amount of plaque or lipid in the abdomen or aortic arch, and neither metformin-or taslutide-treated animals showed any appreciable alterations in the buildup of aortic macrophages [5].

| Solubility (In Vivo) |
Solubility in Formulation 1: 1.25 mg/mL (0.37 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 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: 1.25 mg/mL (0.37 mM) 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; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 12.5 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.) |

*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.
