Description: Pasireotide acetate (formerly SOM230), the acetate salt of Pasireotide, is a stable cyclohexapeptide somatostatin derivative 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.
