Seglitide (MK-678) is an orally active, selective SSTR2 agonist and somatostatin analog. Seglitide also acts as a competitive Somatostatin receptor antagonist, with pA2 values of 6.50, 6.24 and 6.09 against SS14, SS25 and SS28, respectively. Seglitide produces only weak, transient inhibition of myocardial contractility in isolated right atria of guinea pigs. Seglitide inhibits glucagon secretion and reduces circulating insulin levels. Seglitide causes a sustained, reversible reduction in elevated systolic blood pressure in streptozotocin (HY-13753)-induced diabetic rats, but exerts no effect on spontaneously hypertensive rats. Seglitide induces membrane hyperpolarization and inhibits electrical excitability. Seglitide induces concentration-dependent contraction and significant desensitization in isolated distal colon of rats.
