Antimicrobial
An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are microbicides, while those that merely inhibit their growth are called bacteriostatic agents. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis. The main classes of antimicrobial agents are disinfectants (non-selective agents, such as bleach), which kill a wide range of microbes on non-living surfaces to prevent the spread of illness, antiseptics (which are applied to living tissue and help reduce infection during surgery), and antibiotics (which destroy microorganisms within the body ...

Chlorinated
In chemistry, halogenation is a chemical reaction that entails the introduction of one or more halogens into a compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. This kind of conversion is in fact so common that a comprehensive overview is challenging. This article mainly deals with halogenation using elemental halogens (F2, Cl2, Br2, I2). Halides are also commonly introduced using salts of the halides and halogen acids. Many specialized reagents exist for and introducing halogens into diverse substrates, e.g. thionyl chloride. Organic chemistry Several pathways exist for the halogenation of organic compounds, including free radical halogenation, ketone halogenation, electrophilic halogenation, and halogen addition reaction. The nature of the substrate determines the pathway. The facility of halogenation is influenced by the halogen. Fluorine and chlorine are more electrophilic ...

8-Hydroxyquinoline
8-Hydroxyquinoline (also known as oxine) is a chelating agent which has been used for the quantitative determination of metal ions. In aqueous solution 8-hydroxyquinoline has a pKa value of ca. 9.9 It reacts with metal ions, losing the proton and forming 8-hydroxyquinolinato- chelate complexes. The aluminium complex is a common component of organic light-emitting diodes (OLEDs). Variations in the substituents on the quinoline rings affect its luminescence properties. In the photochemically induced excited-state zwitterionic isomers are formed in which the hydrogen atom is transferred from oxygen to nitrogen. The complexes as well as the heterocycle itself exhibit antiseptic, disinfectant, and pesticide properties, functioning as a transcription inhibitor. Its solution in alcohol is used in liquid bandages. It once was of interest as an anti-cancer drug. A thiol analogue, 8-mercaptoquinoline is also known. The roots of the invasive plant '' Centaurea diffusa'' rele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throat Lozenge
A throat lozenge (also known as a cough drop, sore throat sweet, troche, cachou, pastille or cough sweet) is a small, typically medicated tablet intended to be dissolved slowly in the mouth to temporarily stop coughs, lubricate, and soothe irritated tissues of the throat (usually due to a sore throat or strep throat), possibly from the common cold or influenza. Cough tablets have taken the name lozenge, based on their original shape, a diamond. Ingredients Lozenges may contain benzocaine, an anaesthetic, or eucalyptus oil. Non-menthol throat lozenges generally use either zinc gluconate glycine or pectin as an oral demulcent. Several brands of throat lozenges contain dextromethorphan. Other varieties such as Halls contain menthol, peppermint oil and/or spearmint as their active ingredient(s). Honey lozenges are also available. The purpose of the throat lozenge is to calm the irritation that may be felt in the throat while swallowing, breathing, or even drinking ...

Amebicide
An amebicide (or amoebicide) is an agent that is destructive to amoeba, especially parasitic amoeba that cause amoebiasis. Entamoeba * Metronidazole, or a related drug such as Tinidazole, Secnidazole or Ornidazole, is used to destroy amoebae that have invaded tissue. * Several drugs are available for treating intestinal infections, the most effective of which has been shown to be Paromomycin (also known as Humatin). ''E. histolytica'' infections occur in both the intestine and (in people with symptoms) in tissue of the intestine and/or liver. As a result, both tissue and luminal drugs are needed to treat the infection, one for each location. Metronidazole is usually given first, followed by Paromomycin or Diloxanide. ''E. dispar'' does not require treatment, but many laboratories (even in the developed world) do not have the facilities to distinguish this from ''E. histolytica''. Tissue amebicides Metronidazole, or a related drug such as tinidazole, secnidazole or ornidazole, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiprotozoal Agents
Antiprotozoal agents ( ATC code: ATC P01) is a class of pharmaceuticals used in treatment of protozoan infection. A paraphyletic group, protozoans have little in common with each other. For example, ''Entamoeba histolytica'', a unikont eukaryotic organism, is more closely related to ''Homo sapiens'' (humans), which also belongs to the unikont phylogenetic group, than it is to ''Naegleria fowleri'', a "protozoan" bikont. As a result, agents effective against one pathogen may not be effective against another. Antiprotozoal agents can be grouped by mechanism or by organism. Recent papers have also proposed the use of viruses to treat infections caused by protozoa. Medical uses Antiprotozoals are used to treat protozoal infections, which include amebiasis, giardiasis, cryptosporidiosis, microsporidiosis, malaria, babesiosis, trypanosomiasis, Chagas disease, leishmaniasis, and toxoplasmosis. Currently, many of the treatments for these infections are limited by their toxicity. Outda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiseptics
An antiseptic (from Greek ἀντί ''anti'', "against" and σηπτικός ''sēptikos'', "putrefactive") is an antimicrobial substance or compound that is applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from ''antibiotics'' by the latter's ability to safely destroy bacteria within the body, and from ''disinfectants'', which destroy microorganisms found on non-living objects. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper '' Antiseptic Principle of the Practice of Surgery'' in 1867 by Joseph Lister, which was inspired by Louis Pa ...

Chloroarenes
In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. The haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties. The most important members are the aryl chlorides, but the class of compounds is so broad that there are many derivatives and applications. Preparation The two main preparatory routes to aryl halides are direct halogenation and via diazonium salts. Direct halogenation In the Friedel-Crafts halogenation, Lewis acids serve as catalysts. Many metal chlorides are used, examples include iron(III) chloride or aluminium chloride. The most important aryl halide, chlorobenzene is produced by this route. Monochlorination of benzene is always accompanied by formation of the dichlorobenzene derivatives. Arenes with electron donating groups react with halogens even in the absence ...
