Conivaptan hydrochloride (YM 087) is an orally active dual vasopressin V1a/V2 receptor antagonist with Ki values of 0.48 nM and 3.04 nM for vasopressin V1a receptor and V2 receptor, respectively. Conivaptan hydrochloride competitively and reversibly blocks vasopressin-mediated antidiuresis, vasoconstriction, and cellular hypertrophy, while inhibiting CYP3A4. Conivaptan hydrochloride inhibits vasopressin-induced intracellular calcium, cAMP, and mitogen-activated kinase activation in vascular smooth muscle cells and cardiomyocytes. Conivaptan hydrochloride induces water diuresis while improving hemodynamics in heart failure models, reducing left ventricular end-diastolic pressure, vascular resistance, and organ weight. Conivaptan hydrochloride is used for research on hyponatremia and congestive heart failure .

Trequinsin hydrochloride (HL 725) is a PDE inhibitor, CatSper channel activator, and sperm potassium channel modulator. Trequinsin hydrochloride targets PDE3 with an IC50 of <1 nM. Trequinsin hydrochloride enhances currents and elevates intracellular calcium and cGMP levels via direct activation of the CatSper channel, while inhibiting the outward current conductance of sperm potassium channels. Without inducing premature acrosome reaction, Trequinsin hydrochloride significantly enhances sperm hyperactivated motility, forward motility, and the ability to penetrate viscous media. Trequinsin hydrochloride exerts age-specific positive inotropic and positive lusitropic effects on rabbit ventricular papillary muscles. Trequinsin hydrochloride has been used in studies on the mechanisms underlying male infertility (e.g., asthenozoospermia) .

Murrayafoline A is a carbazole alkaloid that can be extracted from Murraya tetramera. Murrayafoline A directly targets Specificity protein 1 (Sp1), thereby inhibiting NF-κB and MAPK signaling pathways. Murrayafoline a induces a G0/G1-phase arrest in platelet-derived growth factor (PDGF)-stimulated vascular smooth muscle cells. Murrayafoline A attenuates the Wnt/β-catenin pathway by promoting the degradation of intracellular β-catenin proteins. Murrayafoline A enhances the contraction of rat ventricular myocytes and L-type calcium current by activating protein kinase C. Murrayafoline A inhibits LPS (HY-D1056)-induced neuroinflammation in vivo. Murrayafoline A can be used for the study of inflammation, vascular complications and colon cancer .

Aprindine is an Ib-class anti-arrhythmic agent. Aprindine mainly exerts its effect by blocking sodium channels (INa), thereby reducing the excitability and conduction velocity of cardiac muscle cells. Aprindine significantly inhibits delayed potassium currents, which helps to prolong the atrial effective refractory period (AERP) and inhibit the occurrence of atrial fibrillation. Aprindine can also regulate intracellular calcium ion concentration by inhibiting Na +/Ca 2+ exchange current (INCX), thereby further stabilizing cardiac electrical activity. Aprindine can be used for the study of atrial fibrillation (AF) and ventricular arrhythmias .

Barucainide is an Ib-class anti-arrhythmic agent (moderately blocking sodium channel). Barucainide exhibits concentration-dependent inhibitory effects on the maximum upstroke velocity (Vmax) of Purkinje fibers and ventricular muscle in dogs. Barucainide significantly shortens the action potential duration (APD). Barucainide significantly inhibits the pacemaker activity frequency of atrial tissue in rabbits and the enhanced automaticity of Purkinje fibers under normal resting potential in response to isoproterenol. Barucainide cannot inhibit the abnormal automaticity emission frequency of canine Purkinje fibers induced by barium. Barucainide can be used for research on arrhythmias .

LND 796 is an aminosteroidal derivative with positive inotropic effects similar to those of digitalis. It exhibits electrophysiological, toxic, and inotropic effects in normal and partially potassium-depolarized ventricular muscles. LND 796 requires higher concentrations than digoxin to induce the same toxic symptoms. It exhibits a concentration-dependent positive inotropic effect on guinea pig papillary muscles in normal potassium solution. In partially potassium-depolarized papillary muscles, LND 796 enhances both components of contraction and increases the amplitude of slow action potentials. The mechanism of positive inotropic action of LND 796 involves enhanced calcium entry in calcium channels and inhibition of sodium-potassium ATPase. Due to its expanded positive inotropic range, LND 796 may have potential application in the treatment of congestive heart failure.
