Cat. No.: HY-106103
CAS No.: 81377-02-8
Purity:  99.30%
Synonyms: MK-678; L-363586
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 .

Tyr-α-CGRP (human) TFA is an N-terminally extended human α-CGRP analog. Tyr-α-CGRP (human) TFA can bind to membrane preparations from rat brain and spleen with IC50 values of 0.2 nM and 0.5 nM, respectively, and induce positive chronotropic and inotropic effects in isolated guinea pig right and left atria with EC50 values of 282 nM and 74 nM, respectively. Tyr-α-CGRP (human) TFA also inhibits contractile responses in rat vas deferens with an EC50 value of 1.9 nM .

ORF 17583 is a Ranitidine (HY-B0693) analogue and H2 receptor antagonist. ORF 17583 exhibits typical reversible competitive antagonism in the guinea pig right atria model, causing a dose-dependent rightward shift of the histamine concentration-response curve without reducing the maximum effect, and its action is fully reversible upon washing. ORF 17583 can be used for research on peptic ulcers and hyperacidity .

ICI 147798 is an orally effective β-adrenoceptor antagonist with a pKB of 9.1 (in guinea pig right atrium) and 8.8 (in guinea pig trachea). ICI 147798 acts as a diuretic and intraocular pressure-lowering agent. ICI 147798 blocks β-adrenoceptors, inhibits isoproterenol-induced tachycardia and vasodepressor responses, exhibits slowly dissociating, insurmountable antagonism against β1-adrenoceptors, and shows surmountable competitive antagonism against β2-adrenoceptors. ICI 147798 induces natriuresis and kaliuresis, inhibits sodium transport, and reduces intraocular pressure .

Bucumolol is an orally active β-adrenergic receptor blocker. Bucumolol inhibits Renin release. Bucumolol exhibits activities including local anesthesia, antiarrhythmia, antihypertension, heart rate reduction, negative inotropy, cardiac action potential inhibition, and action potential duration shortening. Bucumolol does not increase cardiac electrical threshold, prolong atrial refractory period, or affect body weight in rodents. Bucumolol can be used in research related to arrhythmia and hypertension .

Antiulcer Agent 3 is a orally active histamine H2-receptor competitive antagonist (pA2 = 6.7). Antiulcer Agent 3 reduces gastric acid secretion. Antiulcer Agent 3 reduces gastric lesions in water-immersion stress-induced ulcer rat models. Antiulcer Agent 3 protects against HCl-ethanol-induced gastric lesions in rats. Antiulcer Agent 3 can be used for the research of peptic ulcer disease .
