Pasireotide (diaspartate)  (Synonyms: SOM230 (diaspartate))

Pasireotide (SOM230) diaspartate, 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 diaspartate exhibits antisecretory, antiproliferative, and proapoptotic activity^[1][2].

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

Pasireotide diaspartate 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 diaspartate 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^[1].

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