Isoproterenol sulfate anhydrous is a useful alkaloid. It is used for biological research.

Isoproterenol bitartrate is a beta-sympathomimetic and an isopropyl analog of Epinephrine, which acts on the heart, bronchi, skeletal muscle, and alimentary tract. It is used mainly as a bronchodilator and heart stimulant.

Isoproterenol tartrate, (-)- is a beta-Adrenoceptor agonist agent that increases cytosolic cAMP.

(S)-Isoproterenol bitartrate is a bioactive chemical.

Isoproterenol-d7 is intended for use as an internal standard for the quantification of isoproterenol by GC- or LC-MS. Isoproterenol is an agonist of β1- and β2-adrenergic receptors (β1- and β2-ARs; Kis = 224 and 458 nM, respectively). It is selective for β1- and β2-ARs over β3-ARs (Ki = 1,570 nM). Isoproterenol inhibits contractions in isolated field-stimulated rat vas deferens (EC50 = 45.6 nM). In vivo, isoproterenol (0.33 mg kg) decreases blood pressure and increases water intake in nephrectomized rats. It reduces blood pressure and increases heart rate in renal hypertensive rabbits. Isoproterenol inhibits histamine-induced bronchospasms in anesthetized dogs. Formulations containing isoproterenol have been used in the treatment of bradydysrhythmias and to improve breathing during anesthesia.

(-)-Isoproterenol hydrochloride is used as a β-adrenergic receptor agonist in the treatment of bradycardia and as a bronchodilator.

Dichloroisoproterenol hydrochloride is a biochemical. It may be used for cardiac arrhythmia.

Dichloroisoproterenol is also known as Dichloroisoprenaline (DCI), was the first beta blocker ever to be developed. It is non-selective for the β1-adrenergic and β2-adrenergic receptors. DCI has low potency and acts as a partial agonist antagonist at these receptors. Dichloroisoprenaline is a racemic mixture of enantiomers.

Bisaramil hydrochloride (Bisaramil) is a novel diazabicyclononane antiarrhythmic compound that inhibits the generation of free radicals.Bisaramil hydrochloride blocks sodium currents and inhibits the slow Ca(2+) action potential induced by isoproterenol in K(+)-depolarized muscle.

Sinapinic Acid (Synapoic acid) protects the rat liver from CCl4-induced inflammation, most likely by acting as a free radical scavenger and modulator of NF-κB p65 activation and proinflammatory cytokine expression. Sinapic acid with antioxidant role protects cardiac cells and its functions from I R induced oxidative stress. Sinapic acid is a potentially useful agent for the protection against liver fibrosis and cirrhosis. Sinapic acid prevents the alterations in the levels of lipids and lipoproteins by virtue of its anti-lipidaemic effect in isoproterenol induced myocardial infarcted rats. Sinapic acid ameliorates hyperglycemia through PLC-PKC signals to enhance the glucose utilization in diabetic rats.

Isoprenaline (Norisodrine) is a non-selective and orally active β-adrenoceptor agonist.Isoproterenol is a potent peripheral vasodilator and bronchodilator.Isoproterenol can be used in the study of bradycardia and bronchial asthma for the treatment of heart block, bradycardia.

ISO24 refers to the infusion of isoproterenol at a rate of 24 ng kg min. After 120 minutes of infusion, ISO24 results in a 27% decrease in plasma leptin levels while also increasing plasma insulin levels.

O-Desmethylcarvedilol (Desmethylcarvedilol) is an active metabolite of Carvedilol, a non-selective β-adrenergic receptor (β-AR) antagonist. This compound inhibits store overload-induced calcium release in HEK293 cells expressing the RyR2 R4496C mutation (IC50= 7.62 µM). Additionally, O-Desmethylcarvedilol slows the increase in heart rate and prevents diastolic pressure reduction induced by Isoproterenol in conscious rabbits (ED50s = 32 and 5 µg kg).

Esmolol acid (ASL-8123) hydrochloride is a mild antagonist of β-adrenergic receptors. It inhibits the heart rate and diastolic pressure responses induced by Isoproterenol in a dose-dependent manner and is applicable for renal failure research.

SB 204741 is a selective 5-HT2B antagonist with high affinity and pKi value of 7.1.

Rimiterol, a beta 2 stimulant, therefore affects the cardiovascular system less than isoproterenol.

Propofol β-D-Glucuronide is the major inactive metabolite of isoproterenol sulfate (a short-acting anesthetic), mediated by UDP-glucuronosyltransferase (UGT), and can be used to study sleep deprivation (SD).

Cyclic ADP-ribose (cADP-ribose) is an endogenous metabolite of NAD+ that mobilizes the release of stored Ca2+ in the endoplasmic reticulum via ryanodine receptors in various cell types.[1],[2],[3],[4],[5] This second messenger is generated via the cADP-ribose synthases CD38 and CD157.[6],[5],[7] cADP-Ribose may also trigger the cell surface Ca2+ influx channel TRPM2 in a temperature-dependent manner.[8] In vitro, cADP-ribose modulates Ca2+ signaling in rat and mouse cardiomyocytes treated with isoproterenol , and treatment with this metabolite at 100 μM under heat stress conditions induces the release of oxytocin from the mouse hypothalamus.[9],[4]

FFA2 allosteric agonist. Inhibits forskolin-induced cAMP increase and stimulates 35SGTPγS binding in biochemical assays (pEC50 values are 6.9 and 7.23, respectively). Binds at allosteric binding site. In functional assays, displays positive allosteric modulation of FFA-induced Gi signaling and negative allosteric modulation of FFA-induced Gq/G11 signaling. Inhibits lipolytic effect of isoproterenol (pEC50 = 5.03) and induces migration of human neutrophils in vitro.

Clofeverine (free base) is a highly selective relaxant for gastrointestinal smooth muscles with a beta-receptor stimulative nature. On isolated ileum, the inhibitory effect of clofeverine for spontaneous motility was comparable to that of isoproterenol and 100 times higher than that of papaverine.

Clofeverine hydrochloride is the salt form of Clofeverine (free base), a highly selective relaxant for gastrointestinal smooth muscles with a beta-receptor stimulative nature. On isolated ileum, the inhibitory effect of clofeverine for spontaneous motility was comparable to that of isoproterenol and 100 times higher than that of papaverine.

Protokylol hydrochloride is the salt form of Protokylol (free base) (Asmetil, Caytine, Palison, Ventaire), a β-adrenergic receptor agonist used as a bronchodilator in Europe and the United States. It is methylenedioxyphenyl-isoproterenol.

Fenspiride-d5 is intended for use as an internal standard for the quantification of fenspiride by GC- or LC-MS. Fenspiride is an antagonist of histamine H1 receptors and a non-steroidal anti-inflammatory drug (NSAID). It inhibits histamine-induced contraction of isolated guinea pig trachea but not histamine-induced inotropy of isolated guinea pig heart. It also inhibits phosphodiesterase 4 (PDE4), PDE5, and PDE3 (IC50s = 69, ~158, and 363 µM, respectively, in isolated human bronchi derived from patients with lung cancer). It is selective for these phosphodiesterases over PDE1 and PDE2, where it provides less than 25% inhibition. Fenspiride potentiates the airway relaxant effects of isoproterenol and sodium nitroprusside indicating an effect on cAMP and cGMP phosphodiesterases, respectively. Aerosolized fenspiride (1 mg ml) reverses bronchoconstriction induced by capsaicin and, when used at aerosolized concentrations ranging from 1-10 mg ml, reduces cough induced by citric aci......
