Summary

Pasireotide (SOM230) ditrifluoroacetate, a long-acting cyclohexapeptide somatostatin analogue, can improve agonist activity at somatostatin receptors (subtypes sst1/2/3/4/5 , pK i =8.2/9.0/9.1/<7.0/9.9, respectively). Pasireotide ditrifluoroacetate exhibits antisecretory, antiproliferative, and proapoptotic activity [1] [2] .


IC50 & Target

pKi: 8.2 (sst1), 9.0 (sst2), 9.1 (sst3), <7.0 (sst4), 9.9 (sst5) [1]


In Vitro

Pasireotide ditrifluoroacetate exhibits unique high-affinity binding to human somatostatin receptors (subtypes sst1/2/3/4/5, pK i =8.2/9.0/9.1/<7.0/9.9, respectively) [1] .
Pasireotide ditrifluoroacetate effectively inhibits the growth hormone releasing hormone (GHRH) induced growth hormone (GH) release in primary cultures of rat pituitary cells, with an IC 50 of 0.4 nM [1] .

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


In Vivo

Pasireotide ditrifluoroacetate (160 mg/kg/mouth; s.c. for 4 months) significantly decreases the serum insulin, increases serum glucose, reduces the tumor size and increases apoptosis in Pdx1-Cre [2] .
Pasireotide ditrifluoroacetate (2-50 μg/kg; s.c. twice daily for 42 days) exerts the antinociceptive and antiinflammatory actions via the SSTR2 receptor in a mouse model of immune-mediated arthritis [3] .

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

Animal Model: 12 month-old conditional Men1 knockout mice with insulinoma [2]
Dosage: 160 mg/kg/mouth
Administration: S.c. every month for 4 months
Result: Decreased the serum insulin from 1.060 μg/L to 0.3653 μg/L and increased the serum glucose from 4.246 mM to 7.122 mM.
Significantly reduced the tumor size and increased apoptosis.
