  • HY-P3433
    Sarafotoxin S6b

    		Endothelin Receptor Cardiovascular Disease
    Sarafotoxin S6b is a vasoconstrictor peptide, and a non-selective endothelin receptor agonist. Sarafotoxin S6b can induce contraction in isolated human coronary arteries , the Ki values of Coronary artery, Saphenous vein and Coronary artery are 0.27, 0.55 and 19.5 nM, respectively .

  • HY-114920
    Piprofurol

    		Calcium Channel Cardiovascular Disease
    Piprofurol is a calcium channel inhibitor. Piprofurol inhibits the calcium-induced contractions in isolated potassium depolarized preparations of rat aorta in a concentration-dependent manner and relaxes the K +-induced contraction of the dog coronary artery and the rabbit basilar artery. Piprofurol exerts a negative inotropic effect on guinea-pig papillary muscle, with the EC50 of 5 μM .

    [Lys4] Sarafotoxin S6c

    		Endothelin Receptor Cardiovascular Disease
    [Lys4] Sarafotoxin S6c, a sarafotoxin analogue, is a potent and partial agonist of endothelin receptor. [Lys4] Sarafotoxin S6c elicits contraction of pig coronary artery, with an EC50 of 1.5 nM .

    Nipradolol

    KT 210; K 351; Hypadil

    		 Adrenergic Receptor Cardiovascular Disease
    Nipradolol (KT-210; K-351) is a potent blocker of alpha-1-adrenergic receptors. Nipradolol inhibits the increase of intraocular pressure (IOP) in an albino rabbit model induced by Phenylephrine (HY-B0769). Nipradolo suppresses the noradrenaline (NA)-induced muscles contraction, also exhibits vasodilator activity on the dog coronary artery .

    (-)-Niguldipine hydrochloride

    (R)-Niguldipine hydrochloride

    		 Calcium Channel Cardiovascular Disease
    (-)-Niguldipine ((R)-Niguldipine) hydrochloride is a calcium channel antagonist. (-)-Niguldipine hydrochloride exerts a vasodilatory effect by blocking calcium channels and reducing the transmembrane influx of calcium ions. (-)-Niguldipine can inhibit U-46619 (HY-108566)-induced coronary artery contraction in guinea pig Langendorff hearts (pID50 of 9.93), has high affinity for calcium channel binding sites on guinea pig skeletal muscle membranes (Ki of 8.10), and lowers blood pressure in spontaneously hypertensive rats (pED30 of 5.55). (-)-Niguldipine hydrochloride can improve cardiovascular diseases such as hypertension, angina pectoris, and arrhythmias .
