Description

Taspoglutide is a long-acting glucagon-like peptide 1 (GLP-1) receptor agonist developed for treatment of type 2 diabetes, with an EC₅₀ value of 0.06 nM.

IC₅₀ & Target

EC50: 0.06 nM (GLP-1)^[1]

In Vitro

Taspoglutide (R1583/BIM51077) is a long acting 10% formulation of (Aib8-35) human GLP-1 (7-36 amides) with 93% homology with the native polypeptide. It activates the GLP-1 receptor. Taspoglutide has comparable affinity (affinity constant 1.1±0.2 nM) to the natural ligand (affinity constant 1.5±0.3 nM) for the hGLP-1 receptor and exhibits comparable potency in stimulating cAMP production^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Taspoglutide has been shown to enhance the rate of glucose-induced insulin secretion from isolated, cultured rat islets and the perfused ZDF rat pancreas. Taspoglutide in Sprague-Dawley rats and diabetic db/db mice have shown a dose-related enhancement of glucose-dependent insulin release, which lower blood glucose in the db/db mouse model of type 2 diabetes^[3]. Acute treatment with taspoglutide reduces glucose excursion and increased insulin response during oGTT. In chronically treated rats, glucose excursion and levels of GIP, PYY and triglycerides during oGTT on day 21 are significantly reduced^[4]. Hepatic triglyceride levels are significantly reduced in livers from taspoglutide-treated. Taspoglutide does not reduce plaque area or lipid content in the aortic arch or abdominal aorta, and no significant change in aortic macrophage accumulation is detected after taspoglutide or metformin mice^[5].

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 1.25 mg/mL (0.37 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 1.25 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 1.25 mg/mL (0.37 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 1.25 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.

Animal Administration
^[4]^[5]

Rats: The Zucker diabetic fatty (ZDF) rats (animal model of type 2 diabetes) are used in the study. ZDF rats are treated acutely (0.1, 1, 10 μg/kg) or chronically (sustained-release of 1 mg) with a single long-acting dose of taspoglutide. Pioglitazone is used as a positive control in the chronic study. Postprandial glucose, body weight, glycaemic control and insulin sensitivity are assessed over 21 days in chronically treated animals^[4].

Mice: High-fat diet-fed male ApoE^-/- mice are used in the study. Mice with glucose levels from 15-25 mM are then randomized to different groups and treated for 12 wk with a once-monthly sc 0.4-mg taspoglutide microtablet suspension, a sc placebo microtablet, or metformin (400 mg/kg*d) continuously provided in the drinking water plus a sc placebo microtablet^[5].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
