| Bioactivity | 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[1][2]. | ||||||
| Target | pKi: 8.2 (sst1), 9.0 (sst2), 9.1 (sst3), <7.0 (sst4), 9.9 (sst5) | ||||||
| Invitro | 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)[1].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[1]. | ||||||
| In Vivo | 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[2].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[3].
