PSB36 is a highly selective A1 adenosine receptor antagonist, with a Ki of 0.12 nM and a Kd of 0.7 nM. Systemic administration of PSB36 reduces formalin- and Carrageenan (HY-125474)-induced edema in mice and decreases pain-related behaviors, with no local paw activity. PSB36 prolongs the APD90 of rat and human atria, produces a frequency-dependent prolongation of rat atrial ERP, increases the diastolic threshold of rat atria, and shortens the duration of atrial fibrillation episodes. PSB36 can be used in research related to inflammatory pain, inflammatory hyperalgesia, edema and atrial fibrillation .

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. Seglitide can be used in research related to hypertension complicated with insulin-dependent diabetes mellitus .

Neurological Disease

SB-203186 is a highly selective 5-HT4 receptor antagonist. SB-203186 exhibits a potent competitive antagonistic effect, with its pKB value being 8.3 in the isolated right atrium model of piglets. SB-203186 can dose-dependently shift the 5-HT-induced tachycardia curve to the right, and does not inhibit the maximum response. SB-203186 is an efficient 5-HT₄ antagonist in pig and human atria, but has no significant inhibitory effect in rat atria. SB-203186 can be used for the study of diseases such as arrhythmias and abnormal myocardial contraction .

Potassium Channel

Research Areas:  

Cardiovascular Disease

Inakalant is an atrial specific potassium channel blocker with antiarrhythmic activity. Inakalant works by selectively blocking potassium channels in heart cells, thereby prolongs the action potential duration (APD) of cardiomyocytes and increases the effective refractory period of the atria and ventricles, which helps to terminate and prevent the occurrence of arrhythmias such as atrial fibrillation (AF). Inakalant can be used in the study of arrhythmia and cardiac electrophysiology .
