Pasireotide L-aspartate, formerly known as SOM230, is a potent and stable cyclohexapeptide somatostatin mimic that exhibits unique high-affinity binding to human somatostatin receptors (subtypes sst1/2/3/4/5, pKi=8.2/9.0/9.1/<7.0/9.9 respectively). It is an orphan drug approved for the treatment of Cushing's disease in patients who fail or are ineligible for surgical therapy. It was developed by Novartis. Pasireotide is a somatostatin analogue with a 40-fold increased affinity to somatostatin receptor 5 compared to other somatostatin analogues.
ln Vitro |
When bound to human somatostatin receptors (subtypes sst1/2/3/4/5, pKi 8.2/9.0/9.1/<7.0/9.9, respectively), pasireotide L-aspartate demonstrates a unique high-affinity binding [1]. In primary cultures of rat pituitary cells, pasireotide L-aspartate efficiently suppresses growth hormone-releasing hormone (GHRH)-induced growth hormone (GH) production with an IC50 of 0.4 nM [1].

ln Vivo |
The administration of pasireotide L-aspartate (160 mg/kg/oral; subcutaneous injection for 4 months) to Pdx1-Cre resulted in significant changes in blood glucose, tumor growth, apoptosis, and serum insulin levels [2]. In a mouse model of immune-mediated arthritis, pasireotide L-aspartate (2-50 μg/kg; subcutaneously administered twice daily for 42 days) acts as an analgesic and anti-inflammatory agent via the SSTR2 receptor [3].

Animal Protocol |
Animal/Disease Models: 12-month-old conditional Men1 gene knockout insulinoma mice [2]
Doses: 160 mg/kg/oral Route of Administration: monthly subcutaneous injection for 4 months Experimental Results: Serum insulin diminished from 1.060 μg/L to 0.3653 μg/L, and increased blood sugar from 4.246 mM to 7.122 mM. Dramatically diminished tumor size and increased apoptosis. |

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).

*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.
