Emopamil is a calcium channel blocker and a high-affinity ligand of human sterol isomerase. [1]

Contents

Structure

Emopamil's structure consists of an organic amino compound, nitrile compound and a member of two benzene rings.

Applications

Emopamil also known as EMP is a phenylalkylamine and inhibitor of 5-hydroxytryptamine 5-HT2 receptors. [2] EMP includes a chiral quaternary carbon center, and research has indicated that its optical isomers have different biological effects. [3] It interacts in an extracellular site of the nerve cell to inhibit calcium channel responses while other phenylalkylamines act at an intracellular site. The interaction site of emopamil suggests to its greater neuroprotective efficacy in research related to ischaemia. [4]

Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists are a group of medications that disrupt the movement of calcium through calcium channels. Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension. CCBs are particularly effective against large vessel stiffness, one of the common causes of elevated systolic blood pressure in elderly patients. Calcium channel blockers are also frequently used to alter heart rate, to prevent peripheral and cerebral vasospasm, and to reduce chest pain caused by angina pectoris.

<span class="mw-page-title-main">Neurotoxin</span> Toxin harmful to nervous tissue

Neurotoxins are toxins that are destructive to nerve tissue. Neurotoxins are an extensive class of exogenous chemical neurological insults that can adversely affect function in both developing and mature nervous tissue. The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol, glutamate, nitric oxide, botulinum toxin, tetanus toxin, and tetrodotoxin. Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations.

Cytochrome P450 3A4 is an important enzyme in the body, mainly found in the liver and in the intestine, which in humans is encoded by CYP3A4 gene. It oxidizes small foreign organic molecules (xenobiotics), such as toxins or drugs, so that they can be removed from the body. It is highly homologous to CYP3A5, another important CYP3A enzyme.

<span class="mw-page-title-main">Farnesyl-diphosphate farnesyltransferase</span> Class of enzymes

Squalene synthase (SQS) or farnesyl-diphosphate:farnesyl-diphosphate farnesyl transferase is an enzyme localized to the membrane of the endoplasmic reticulum. SQS participates in the isoprenoid biosynthetic pathway, catalyzing a two-step reaction in which two identical molecules of farnesyl pyrophosphate (FPP) are converted into squalene, with the consumption of NADPH. Catalysis by SQS is the first committed step in sterol synthesis, since the squalene produced is converted exclusively into various sterols, such as cholesterol, via a complex, multi-step pathway. SQS belongs to squalene/phytoene synthase family of proteins.

<span class="mw-page-title-main">Isopentenyl-diphosphate delta isomerase</span> Class of enzymes

Isopentenyl pyrophosphate isomerase, also known as Isopentenyl-diphosphate delta isomerase, is an isomerase that catalyzes the conversion of the relatively un-reactive isopentenyl pyrophosphate (IPP) to the more-reactive electrophile dimethylallyl pyrophosphate (DMAPP). This isomerization is a key step in the biosynthesis of isoprenoids through the mevalonate pathway and the MEP pathway.

<span class="mw-page-title-main">Anipamil</span> Chemical compound

Anipamil is a calcium channel blocker, specifically of the phenylalkylamine type. This type is separate from its more common cousin Dihydropyridine. Anipamil is an analog of the more common drug verapamil, which is the most common type of phenylalkylamine style calcium channel blocker. Anipamil has been shown to be a more effective antiarrhythmic medication than verapamil because it does not cause hypertension as seen in verapamil. It is able to do this by bonding to the myocardium tighter than verapamil.
