Biological Activity

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. Taspoglutide (R1583, BIM51077) 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.

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.

Chemical Information
Molecular Weight 3339.71
Formula C152H232N40O45
CAS Number 275371-94-3
Solubility (25°C) DMSO 40 mg/mL
Storage -20°C, protect from light, dry, sealed
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
