An SST2 agonist; selectively inhibits cAMP production in cells expressing SST2 over cells expressing SST1, SST3, SST4, or SST5 (EC50s = 25, >1,000, >1,000, >1,000, and >1,000 nM, respectively); reduces GHRH-stimulated growth hormone release in rats at 3, 10, and 30 mg/kg; reduces plasma levels of IGF-1 in beagle dogs
