What is benzimidazole used for?
The benzimidazoles are a large chemical family used to treat nematode and trematode infections in domestic animals. They also have limited activity against cestodes.
Which drug is a benzimidazole derivative?
It is available OTC in Europe. Fenbendazole is a benzimidazole that presents a wide spectrum anthelmintic effect. It is used against a number of gastrointestinal parasites including giardia, roundworms, hookworms, whipworms, the Taenia genus of tapeworms,……Benzimidazole Derivatives.
| Drug | Target | Type |
|---|---|---|
| Thiabendazole | Cytochrome P450 1A1 | enzyme |
Which acid is used for synthesis of benzimidazole?
Synthesis of benzimidazoles has been developed by the o-phenylenediamine with aldehydes using boric acid an efficient catalyst under mild reaction conditions in aqueous media. The product is applicable to aryl and heteroaryl aldehydes. This reaction led to the formation of benzimidazoles new derivatives in good yields.
Is benzimidazole a drug?
Benzimidazole drugs (e.g., anthelmintics albendazole, fenbendazole, oxfenbendazole, thiabendazole, mebendazole; inhibitors of proton pump omeprazole, lansoprasole, pantoprasole) represent substances used in both human and veterinary medicine; however, from the point of view of induction and inhibition of …
Which is commonly used benzimidazole?
In dogs and cats, mebendazole, fenbendazole, febantel, oxfendazole, oxibendazole, and flubendazole are used for treatment of roundworms, hookworms, and tapeworms.
What is benzimidazole anthelmintic?
Benzimidazoles are a chemical class of compounds with broad anthelmintic activity that are vastly used in livestock, horses and pets to control all kinds of parasitic worms (helminths). Some veterinary benzimidazoles are also used as anthelmintics in human medicines.
Is mebendazole a benzimidazole?
Mebendazole, a synthetic benzimidazole, is the agent used most widely in the U.S. for treatment of intestinal helminthiasis, including ascariasis, hookworm infection, trichuriasis, trichostrongyliasis, and enterobiasis.
How do you synthesis benzimidazole?
Place 27 g (0.25 mol) of o-phenylenediamine in a round bottomed flask of 250 ml and add 17.5 g (16 ml, 0.34 mol) of 90% formic acid. Heat the mixture on a water bath at 100 °C for 2 h. Cool and add 10% sodium hydroxide solution slowly, with constant rotation of the flask, until the mixture is just alkaline to litmus.
What is the mechanism for the synthesis of benzimidazole?
The synthesized benzimidazoles compounds were prepared from the condensation reaction between o-Phenylenediamine and various carbonyl compounds, in the presence of ammonium chloride as a catalyst.
What color is benzimidazole?
Benzimidazole is a heterocyclic aromatic organic compound. This bicyclic compound may be viewed as fused rings of the aromatic compounds benzene and imidazole. It is a colorless solid.
Is albendazole a benzimidazole?
Albendazole (Albenza) Albendazole is a benzimidazole carbamate structurally related to mebendazole and has similar anthelmintic activity. Its absorption from the gastrointestinal tract is poor but improved with a concomitant high-fat meal.
What are examples of benzimidazole?
Those of interest are mebendazole, flubendazole, fenbendazole, oxfendazole, oxibendazole, albendazole, albendazole sulfoxide, thiabendazole, thiophanate, febantel, netobimin, and triclabendazole.
What is the toxicity of benzimidazole fungicide?
The major benzimidazole fungicides include benomyl, carbendazim and fuberidazole. Benomyl and carbendazim have a low toxicity, whereas fuberidazole has a moderate toxicity. Benomyl, captan, ammonium salt of alkyldithiocarbamic acid and carbendazim all induced multiple defects in various experimental species.
What are benomyl and carbendazim fungicides?
The benzimidazole fungicides benomyl and carbendazim are extensively used worldwide on a variety of crops (vegetables, fruits, nuts, cereals, cotton, ornamentals, mushrooms, and others) for numerous fungal pests. They have been in use for approximately 30 years with an excellent safety record.
Can multiple benzimidazole fungicides be used as a resistance management tool?
For practical applications, however, fungal isolates resistant to one benzimidazole fungicide usually are resistant to other members of this chemical class. Therefore combinations of various benzimidazole fungicides cannot be used as a resistance management tool.
What are benzimidazole inhibitors?
Benzimidazoles are potent inhibitors of ß-tubulin polymerization in many species of fungi and have been used for plant disease control since the late 1960’s.
