p-Synephrine

alpha-(4-Oxyphenyl)alpha-oxy-beta-methylaminoaethan [German]

C9H13NO2 (167.09462380000002)


Synephrine is a phenethylamine alkaloid that is 4-(2-aminoethyl)phenol substituted by a hydroxy group at position 1 and a methyl group at the amino nitrogen. It has a role as a plant metabolite and an alpha-adrenergic agonist. It is a phenethylamine alkaloid, a member of phenols and a member of ethanolamines. It is a conjugate base of a synephrinium. Synephrine, also referred to as, p-synephrine, is naturally occurring alkaloid. It is present in approved drug products as neo-synephrine, its m-substituted analog. p-synephrine and m-synephrine are known for their longer acting adrenergic effects compared to norepinephrine. The similarity of naming between m-synephrine and the unsubstituted form, synephrine, is a source of some confusion however m-synephrine refers to a related drug more commonly known as phenylephrine. While the compounds share some chemical and pharmacological similarities, they are in fact distinct chemical entities. Synephrine is a natural product found in Citrus medica, Ephedra sinica, and other organisms with data available. Sympathetic alpha-adrenergic agonist with actions like PHENYLEPHRINE. It is used as a vasoconstrictor in circulatory failure, asthma, nasal congestion, and glaucoma. Synephrine (or oxedrine) is a drug commonly used for weight loss. While its effectiveness is widely debated, synephrine has gained significant popularity as an alternative to ephedrine, a related substance which has been made illegal or restricted in many countries due to its use as a precursor in the illicit manufacture of methamphetamine. Products containing bitter orange or synephrine: suspected cardiovascular adverse reactions [citation needed]. Synephrine is derived primarily from the fruit of Citrus aurantium, a relatively small citrus tree, of which several of its more common names include Bitter Orange, Sour Orange, and Zhi shi.; There has been some confusion surrounding synephrine and phenylephrine (neosynephrine), one of its positional isomers. The chemicals are similar in structure; the only difference is the location of the aromatic hydroxyl group. In synephrine, the hydroxyl is at the para position, whereas, in neosynephrine, it is at the meta position. Each compound has differing biological properties.; p-Synephrine is an endogenous amine in plasma, in variable levels with a tendency to be higher in hypertensive patients (PMID 8255371).

Acetaminophen

Bayer select maximum strength headache pain relief formula

C8H9NO2 (151.0633254)


The excellent tolerability of therapeutic doses of paracetamol (acetaminophen) is a major factor in the very wide use of the drug. The major problem in the use of paracetamol is its hepatotoxicity after an overdose. Hepatotoxicity has also been reported after therapeutic doses, but critical analysis indicates that most patients with alleged toxicity from therapeutic doses have taken overdoses. Importantly, prospective studies indicate that therapeutic doses of paracetamol are an unlikely cause of hepatotoxicity in patients who ingest moderate to large amounts of alcohol (PMID: 15733027). Single doses of paracetamol are effective analgesics for acute postoperative pain and give rise to few adverse effects (PMID: 14974073). Acetaminophen (AAP) overdose and the resulting hepatotoxicity is an important clinical problem. In addition, AAP is widely used as a prototype hepatotoxin to study mechanisms of chemical-induced cell injury and to test the hepatoprotective potential of new drugs and herbal medicines. Because of its importance, the mechanisms of AAP-induced liver cell injury have been extensively investigated and controversially discussed for many years (PMID: 16863451).

4-Nonylphenol

P-Nonylphenol (endocrine disrupter)

C15H24O (220.18270539999997)


Environmental pollutant arising from the degradation of nonionic surfactants in sewage Nonoxynol-9, one of the APEs, is used as a surfactant in cleaning and cosmetic products, and as a spermicide in contraceptives. Nonylphenol is an organic compound of the wider family of alkylphenols. It is a product of industrial synthesis formed during the alkylation process of phenols, particularly in the synthesis of polyethoxylate detergents. Because of their man-made origins, nonylphenols are classified as xenobiotics. In nonylphenols, a hydrocarbon chain of nine carbon atoms is attached to the phenol ring in either the ortho (2), meta (3), or para (4) position, with the most common ring isomers being ortho or para (e.g. figure 1 para-nonylphenol). Moreover, the alkyl chains can exist as either linear n-alkyl chains, or complex branched chains. Nonylphenol is commonly obtained as a mixture of isomers, and is thus usually found as a pale yellow liquid at room temperature with a freezing point of -10°C and a boiling point of 295-320°C. However, pure isomers of nonylphenol crystallize readily at room temperatures and for example, para-n-nonylphenol, forms white crystals at room temperature. Nonylphenol, and a related compound tert-octylphenol, were first detected as an air pollutant in New York City and New Jersey, probably due to its evaporation from the Hudson river and other smaller rivers in the region that routinely receive municipal wastewaters. It is possible that the atmosphere is a destructive sink for nonylphenol as it is probably reactive with atmospheric radicals and/or is photoactive.

C18H23NO3 (301.1677848)


Ractopamine (CAS: 97825-25-7) is a beta-agonist livestock feed additive used to increase lean muscle mass. Pharmacologically, ractopamine is a TAAR1 agonist and beta adrenoreceptor agonist that stimulates beta1 and beta2 adrenergic receptors (PMID: 24799633). In clinical use, beta-agonists relax the smooth muscles of airways, thereby resulting in bronchodilation (i.e. widened airways) and easier breathing. In livestock feed, these compounds are able to alter the ratio in which dietary energy intake is distributed between lean and fat tissue. Increasing protein synthesis results in increased muscle fibre size. Ractopamine is banned in over 160 countries including the member nations of the European Union, China, and Russia. Countries such as the United States and South Korea still permit ractopamine use (PMID: 26761809). Serious side effects, including mortality, have been attributed to beta-agonists (e.g. ractopamine and zilpaterol) in cattle and swine. Cooking is not able to completely degrade ractopamine, therefore human exposure to ractopamine is expected in countries where the feed additive is permitted. In humans, beta-agonists containing phenolic hydroxyl groups, are metabolized in the liver and intestine through glucuronidation and sulfation by UDP-glucuronosyltransferase (UGT) 1A6 and 1A9 and sulfotransferase (SULT1A3). Ractopamine is eliminated in urine mostly as its monoglucuronide and monosulfate conjugates (PMID: 27641640). Butopamine, the R,R diastereoisomer, is the most active of ractopamines four diastereoisomers and is responsible for most of the leanness-enhancing effects.
