Semaglutide acetate (NNC-0113-0217; NNC0113-0217), the acetic acid salt form of semaglutide (Ozempic), is a human glucagon-like peptide-1 (GLP-1) receptor agonist with longer duration of antidiabetic action. In order to enhance glycemic control in adults with type 2 diabetes mellitus, the FDA approved semaglutide in December 2017.
Targets |
GLP-1 receptor
|
---|---|
ln Vitro |
Semaglutide is derivatized at lysine 26 and differs from human GLP-1 in two amino acid substitutions (Aib8, Arg34). Semaglutide has an affinity for GLP-1R of 0.38±0.06 nM[1]. With a 94% sequence homology to human GLP-1, semaglutide is an analogue of GLP-1[3].
|
ln Vivo |
Semaglutide has an MRT of 63.6 hours after s.c. dosing to mini-pigs and a plasma half-life of 46 hours in mini-pigs after intravenous administration[1]. Motor impairments caused by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) are ameliorated by semaglutide. Semaglutide also protects dopaminergic neurons in the substantia nigra and striatum by rescuing the decrease in tyrosine hydroxylase (TH) levels, reducing lipid peroxidation, alleviating inflammation, inhibiting the apoptosis pathway, and increasing the expression of autophagy-related proteins. Furthermore, semaglutide, the long-acting GLP-1 analogue, outperforms NN-2211 in the majority of parameters[2].
|
Enzyme Assay |
HEK293‐SNAP‐GLP‐1R cells were labelled in suspension with SNAP‐Lumi4‐Tb (40 nM, Cisbio, Codelet, France) for 1 hour at room temperature in complete medium. After washing and resuspension in hanks' balanced salt solution containing 0.1% bovine serum albumin and metabolic inhibitors (20 mmol/L 2‐deoxygucose and 10 mmol/L NaN3) to prevent GLP‐1R internalization, binding experiments were performed by time‐resolved förster resonance energy transfer (FRET) using exendin (9‐39) with fluorescein isothiocyanate (FITC) installed at position K12 as previously described. [4]
|
Cell Assay |
Semaglutide activates the GLP-1 receptor in pancreatic beta cells leading to glucose-dependent insulin release. It also decreases glucagon secretion, slows gastric emptying, and promotes satiety.
|
Animal Protocol |
Mice: Male C57BL/6 mice 10 weeks old (20-25 g) are used throughout the study. Six groups of mice are randomly assigned (n = 12 per group). The treatments were as follows: (i) saline alone was given to the control group; (ii) NN-2211 group received saline and NN-2211 (25 nmol/kg ip. once daily for 7 days); (iii) Semaglutide group received saline and Semaglutide (25 nmol/kg ip. once daily for 7 days); (iv) MPTP group received MPTP alone (once daily 20 mg/kg ip. for 7 days); (v) MPTP (once daily 20 mg/kg ip. for 7 days) was immediately followed by NN-2211 treated group (25 nmol/kg ip. once daily for 7 days). (vi) MPTP (20 mg/kg i.p. once daily for 7 days), which was immediately followed by the group treated with semaglutide (25 nmol/kg i.p. once daily for 7 days). Measure behavioral changes, neuronal damage, inflammatory markers, and other biomarkers at the conclusion of drug treatments[2].

Additional Infomation |
Novo Nordisk has developed a subcutaneous formulation of semaglutide (Ozempic®), a modified human glucagon-like peptide-1 (GLP-1) analogue, for the treatment of type 2 diabetes mellitus. It has been developed using Novo Nordisk's proprietary protein-acylation technology, and is administered using an injection device. Semaglutide lowers blood glucose by stimulating the release of insulin and also lowers body weight. Once-weekly subcutaneous semaglutide has recently been approved in the US, Puerto Rico and Canada, and has received a positive opinion in the EU for the treatment of patients with type 2 diabetes. It will be launched as the Ozempic® Pen, a pre-filled device. Semaglutide is also under regulatory review in Japan and Switzerland for the treatment of type 2 diabetes. Clinical development for obesity, non-alcoholic steatohepatitis and non-alcoholic fatty liver disease is underway worldwide. This article summarizes the milestones in the development of semaglutide leading to this first approval for type 2 diabetes.[3]
In patients with type 2 diabetes who were at high cardiovascular risk, the rate of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke was significantly lower among patients receiving semaglutide than among those receiving placebo, an outcome that confirmed the noninferiority of semaglutide.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |

5 mM | 0.0479 mL | 0.2396 mL | 0.4792 mL | |
10 mM | 0.0240 mL | 0.1198 mL | 0.2396 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.
