Dioxifedrine
Dioxifedrine (), or dioxifedrin, also known as α-methylepinephrine or as 3,4-dihydroxyephedrine, is a sympathomimetic medication that was never marketed. It is described as a β-adrenergic receptor agonist and bronchodilator. The drug is a substituted phenethylamine and amphetamine and is the catecholamine (3,4-dihydroxylated) derivative of ephedrine and the amphetamine (α-methylated) analogue of epinephrine (adrenaline). Analogues of dioxifedrine include dioxethedrin (α-methyl-''N''-ethylnorepinephrine), corbadrine (levonordefrin; α-methylnorepinephrine), and α-methyldopamine α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine (3,4-DHA or HHA) or as catecholamphetamine, is a research chemical of the catecholamine and amphetamine families.

Dioxethedrin
Dioxethedrin (), or dioxethedrine, also known as 3,4-dihydroxy-''N''-ethylnorephedrine, is a sympathomimetic medication. It was a component of the antitussive syrup Bexol (a combination of dioxethedrin, codeine, and promethazine). It is an ephedrine derivative (and hence is a phenethylamine and amphetamine) and is described as a bronchodilator and β-adrenergic receptor agonist. Analogues of dioxethedrin include dioxifedrine (α-methylepinephrine; 3,4-dihydroxyephedrine), corbadrine (levonordefrin; α-methylnorepinephrine), and α-methyldopamine α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine (3,4-DHA or HHA) or as catecholamphetamine, is a research chemical of the catecholamine and amphetamine families.

Substituted Amphetamine
Substituted amphetamines, or simply amphetamines, are a chemical class, class of compounds based upon the amphetamine structure; it includes all derivative (chemistry), derivative compounds which are formed by replacing, or substitution reaction, substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, Empathogen-entactogen, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and 2,5-dimethoxy-4-methylamphetamine, DOM (STP). Some of amphetamine's substituted Derivative (chemistry), derivatives occur in nature, for example in the leaves of ''Ephedra (genus), Ephedra'' and khat plants. Amphetamine w ...

Corbadrine
Corbadrine, sold under the brand name Neo-Cobefrine and also known as levonordefrin and α-methylnorepinephrine, is a catecholamine sympathomimetic used as a topical nasal decongestant and vasoconstrictor in dentistry in the United States. It is usually used in a pre-mixed solution with local anesthetics, such as mepivacaine. The drug acts as a non-selective agonist of the α1-, α2-, and β-adrenergic receptors. It is said to have preferential activity at the α2-adrenergic receptor. Corbadrine is also a metabolite of the antihypertensive drug methyldopa and plays a role in its pharmacology and effects. Pharmacology Pharmacokinetics Corbadrine is metabolized primarily by catechol ''O''-methyltransferase (COMT). Chemistry Corbadrine, also known as 3,4,β-trihydroxy-α-methylphenethylamine or as 3,4,β-trihydroxyamphetamine, as well as α-methylnorepinephrine or (–)-3,4-dihydroxynorephedrine, is a substituted phenethylamine and amphetamine derivative.

Methamphetamines
Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational or performance-enhancing drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder (ADHD). It has also been researched as a potential treatment for traumatic brain injury. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. ''Methamphetamine'' properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving its potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy such as Adderall an ...

Catecholamines
A catecholamine (; abbreviated CA), most typically a 3,4-dihydroxyphenethylamine, is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. Catechol can be either a free molecule or a substituent of a larger molecule, where it represents a 1,2-dihydroxybenzene group. Catecholamines are derived from the amino acid tyrosine, which is derived from dietary sources as well as synthesis from phenylalanine. Catecholamines are water-soluble and are 50% bound to plasma proteins in circulation. Included among catecholamines are epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. Release of the hormones epinephrine and norepinephrine from the adrenal medulla of the adrenal glands is part of the fight-or-flight response. Tyrosine is created from phenylalanine by hydroxylation by the enzyme phenylalanine hydroxylase. Tyrosine is also ingested directly from dietar ...

Bronchodilators
A bronchodilator or broncholytic (although the latter occasionally includes secretory inhibition as well) is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs. Bronchodilators may be originating naturally within the body, or they may be medications administered for the treatment of breathing difficulties, usually in the form of inhalers. They are most useful in obstructive lung diseases, of which asthma and chronic obstructive pulmonary disease are the most common conditions. They may be useful in bronchiolitis and bronchiectasis, although this remains somewhat controversial. They are often prescribed but of unproven significance in restrictive lung diseases. Bronchodilators are either short-acting or long-acting. Short-acting medications provide quick or "rescue" relief from acute bronchoconstriction. Long-acting bronchodilators help to control and prevent symptoms. The three types of prescr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adrenergic Receptor Agonists
An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α1, α2, β1, β2, and β3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. However, there are also other mechanisms of adrenergic agonism. Epinephrine and norepinephrine are endogenous and broad-spectrum. More selective agonists are more useful in pharmacology. An ' agent is a drug, or other substance, which has effects similar to, or the same as, epinephrine (adrenaline). Thus, it is a kind of sympathomimetic agent. Alternatively, it may refer to something which is susceptible to epinephrine, or similar substances, such as a biological receptor (specifically, the adrenergic receptors). Receptors Directly acting adrenergic agonists act on adrenergic receptors. All adrenergic receptors are G-protein coupled, activating signal transduction pathways. The G-prot ...

α-methyldopamine
α-Methyldopamine (α-Me-DA), also known as 3,4-dihydroxyamphetamine (3,4-DHA or HHA) or as catecholamphetamine, is a research chemical of the catecholamine and amphetamine families. It is a monoamine releasing agent and a metabolite of MDMA and MDA. The ''bis''- glutathionyl metabolite of α-methyldopamine is slightly neurotoxic when directly injected into the brain's ventricles. Role in MDMA-induced serotonergic neurotoxicity Interest in α-methyldopamine lies in the fact that 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxy-''N''-methylamphetamine (MDMA) may not themselves be responsible for their serotonergic neurotoxicity, as an intracerebroventricular injection does not appear to cause neurotoxicity. While many studies suggest excitotoxicity or oxidative stress as likely mechanisms, which may be an effect of MDMA itself, this has led to the search for other mechanisms for the observed toxicity of serotonin axons and subsequent reduction in serotonin (5-HT) a ...
