Pasireotide (SOM230) L-aspartate salt, a long-acting cyclohexapeptide somatostatin analogue, can improve agonist activity at somatostatin receptors (subtypes sst1/2/3/4/5, pKi=8.2/9.0/9.1/<7.0/9.9, respectively). Pasireotide L-aspartate salt exhibits antisecretory, antiproliferative, and proapoptotic activity.
体外研究
Pasireotide L-aspartate salt 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).
Pasireotide L-aspartate salt effectively inhibits the growth hormone releasing hormone (GHRH) induced growth hormone (GH) release in primary cultures of rat pituitary cells, with an IC50 of 0.4 nM.

Pasireotide L-aspartate salt (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.
Pasireotide L-aspartate salt (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.
Animal Model:
12 month-old conditional Men1 knockout mice with insulinoma
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.
