Vapreotide is an exogenous compound that exists as a solid at room temperature. It has the chemical formula C57H70N12O9S2. Vapreotide belongs to the amino acids, peptides, and analogues, a subclass of carboxylic acids and derivatives within the organic compounds. With an average molecular weight of 1,131 g/mol, Vapreotide is a heavy molecule.
This synthetic octapeptide somatostatin analog has been studied for the treatment of cancer. Recorded protein targets for the compound include somatostatin receptor type 2 (SSTR2), somatostatin receptor type 5 (SSTR5), and the Substance-P receptor (TACR1). While the exact mechanism of action is unknown, one study has provided in vitro and in vivo evidence for a tachykinin NK1 receptor antagonist effect in the analgesic effects of vapreotide.
belongs to the class of organic compounds known as hydroxyquinolones. Hydroxyquinolones are compounds containing a quinoline moiety bearing a hydroxyl group and a ketone. Quinoline or benzo[b]pyridine is a bicyclic compound that consists of benzene fused to a pyridine.
The exact mechanism of action is unknown, although one study has provided in vitro and in vivo evidence for a tachykinin NK1 receptor antagonist effect in the analgesic effects of vapreotide (8).
