Tromantadine
Tromantadine is an antiviral medicine used to treat herpes simplex virus. It is available in a topical gel under trade names Viru-Merz and Viru-Merz Serol. Its performance is similar to aciclovir. Like rimantadine, amantadine, and adapromine, tromantadine is a derivative of adamantane. Mechanism Tromantadine inhibits the early and late events in the virus replication cycle. It changes the glycoproteins of the host cells, therefore impeding the absorption of the virus. It inhibits penetration of the virus. It also prevents uncoating of the virions. Synthesis Amide formation between amantadine and chloroacetyl chloride Chloroacetyl chloride is a chlorinated acyl chloride. It is a bifunctional compound, making it a useful building block chemical. Production Industrially, it is produced by the carbonylation of methylene chloride, oxidation of vinylidene chl ... gives N-Adamantan-1-yl-2-chloro-acetamide 689-59-8(1).

Adamantane
Adamantane is an organic compound with a formula C10H16 or, more descriptively, (CH)4(CH2)6. Adamantane molecules can be described as the fusion of three cyclohexane rings. The molecule is both rigid and virtually stress-free. Adamantane is the most stable isomer of C10H16. The spatial arrangement of carbon atoms in the adamantane molecule is the same as in the diamond crystal. This similarity led to the name ''adamantane'', which is derived from the Greek ''adamantinos'' (relating to steel or diamond). It is a white solid with a camphor-like odor. It is the simplest diamondoid. The discovery of adamantane in petroleum in 1933 launched a new field of chemistry dedicated to the synthesis and properties of polyhedral organic compounds. Adamantane derivatives have found practical application as drugs, polymeric materials, and thermally stable lubricants. History and synthesis In 1924, H. Decker suggested the existence of adamantane, which he called decaterpene. The first attempted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rimantadine
Rimantadine (INN, sold under the trade name 'Flumadine'') is an orally administered antiviral drug used to treat, and in rare cases prevent, influenzavirus A infection. When taken within one to two days of developing symptoms, rimantadine can shorten the duration and moderate the severity of influenza. Rimantadine can mitigate symptoms, including fever. Both rimantadine and the similar drug amantadine are derivates of adamantane. Rimantadine is found to be more effective than amantadine because when used the patient displays fewer symptoms. Rimantadine was approved by the Food and Drug Administration (FDA) in 1994. Rimantadine was approved for medical use in 1993. Seasonal H3N2 and 2009 pandemic flu samples tested have shown resistance to rimantadine, and it is no longer recommended to prescribe for treatment of the flu. Medical use Influenza A Rimantadine inhibits influenza activity by binding to amino acids in the M2 transmembrane channel and blocking proton transport ...

Adapromine
Adapromine is an antiviral drug of the adamantane group related to amantadine (1-aminoadamantane), rimantadine (1-(1-aminoethyl)adamantane), and memantine (1-amino-3,5-dimethyladamantane) that is marketed in Russia for the treatment and prevention of influenza. It is an alkyl analogue of rimantadine and is similar to rimantadine in its antiviral activity but possesses a broader spectrum of action, being effective against influenza viruses of both type A and B. Strains of type A influenza virus with resistance to adapromine and rimantadine and the related drug deitiforine were encountered in Mongolia and the Soviet Union in the 1980s. Electroencephalography (EEG) studies of animals suggest that adapromine and related adamantanes including amantadine, bromantane (1-amino-2-bromophenyladamantane), and memantine have psychostimulant-like and possibly antidepressant-like effects, and that these effects may be mediated via catecholaminergic processes. These psychostimulant effects d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Over-the-counter Drug
Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they contain ingredients that are safe and effective when used without a physician's care. OTC drugs are usually regulated according to their active pharmaceutical ingredient (API) rather than final products. By regulating APIs instead of specific drug formulations, governments allow manufacturers the freedom to formulate ingredients, or combinations of ingredients, into proprietary mixtures. The term ''over-the-counter'' (''OTC'') refers to a medication that can be purchased without a medical prescription. In contrast, prescription drugs require a prescription from a doctor or other health care professional and should only be used by the prescri ...

Uncoating
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic mate ...

Deanol
Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH3)2NCH2CH2OH. It is bifunctional, containing both a tertiary amine and primary alcohol functional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic. It is prepared by the ethoxylation of dimethylamine. Industrial uses Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is a precursor to other chemicals, such as the nitrogen mustard 2-dimethylaminoethyl chloride. The acrylate ester is used as a flocculating agent. Related compounds are used in gas purification, e.g. removal of hydrogen sulfide from sour gas streams. Nutraceutical uses The bitartrate salt of DMAE, i.e. 2-dimethylaminoethanol (+)-bitartrate, is sold as a dietary supplement. It is a white powder providing 37% DMAE. Animal tests show possible benefit for improving spatial memory and working memory.Edward D Levin, Jed E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloroacetyl Chloride
Chloroacetyl chloride is a chlorinated acyl chloride. It is a bifunctional compound, making it a useful building block chemical. Production Industrially, it is produced by the carbonylation of methylene chloride, oxidation of vinylidene chloride, or the addition of chlorine to ketene. It may be prepared from chloroacetic acid and thionyl chloride, phosphorus pentachloride, or phosgene. Reactions Chloroacetyl chloride is bifunctional—the acyl chloride easily forms esters and amides, while the other end of the molecule is able to form other linkages, e.g. with amines. The use of chloroacetyl chloride in the synthesis of lidocaine is illustrative: : Applications The major use of chloroacetyl chloride is as an intermediate in the production of herbicides in the chloroacetanilide family including metolachlor, acetochlor, alachlor and butachlor; an estimated 100 million pounds are used annually. Some chloroacetyl chloride is also used to produce phenacyl chloride, ano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
