Benzimidazole and Imidazole Derivatives
Benzimidazole is a compound consisting of a benzene ring fused to an imidazole ring, a five-membered structure containing two nitrogen atoms. Benzimidazole derivatives, such as albendazole, are known for their antiparasitic and antifungal activity, used in the treatment of parasitic infections and certain parasitic diseases in animals and humans. Imidazole, on the other hand, is a five-membered structure with two nitrogen atoms found in various biologically active compounds. Imidazole derivatives, such as metronidazole, have antimicrobial and antiparasitic properties. These compounds are also used in the pharmaceutical industry for treating bacterial infections, parasitic diseases, and some fungal infections, as well as in organic chemistry as catalysts.
At CymitQuimica, we offer high-purity benzimidazoles and imidazoles for research in medicinal chemistry, pharmacology, and biotechnology.

CAS:<p>Rabeprazole is a proton pump inhibitor that is used to treat acid-related disorders such as gastroesophageal reflux disease and peptic ulcers. Rabeprazole inhibits the production of gastric acid by blocking the hydrogen/potassium ATPase that is found in the parietal cells of the stomach. The main mechanism of action for rabeprazole is competitive inhibition of the proton pump, which leads to decreased gastric acid secretion. Rabeprazole can be administered orally or intravenously, with a half-life of about 2 hours. It has been shown to have an effect on human liver cytochrome P450s, but does not affect the activity of recombinant cytochrome P450 3A4 (CYP3A4). In clinical studies, rabeprazole was shown to have no adverse effects on CYP3A4 activity and may even increase it slightly.</p>Formula:C18H21N3O2SPurity:Min. 95%Color and Shape:White PowderMolecular weight:343.44 g/molCarbendazim
CAS:<p>Carbendazim is a fungicide that inhibits the growth of fungi and bacteria. It has been shown to be potent inducers of polymerase chain reaction (PCR) amplification, with a rate constant of 0.0103 per minute. Carbendazim also has a significant effect on electrochemical impedance spectroscopy (EIS). The EIS analysis was used to compare carbendazim-treated cells with untreated cells, which showed that carbendazim causes an increase in the resistance across the cell membrane. This research suggests that carbendazim may be genotoxic, as it increased the amount of DNA damage observed in wild-type strains and altered the optical properties of DNA. Carbendazim is also an effective inhibitor of nitrite ion oxidation and colloidal gold deposition, which has led to its use as a water vapor control agent for plants.</p>Formula:C9H9N3O2Purity:Min. 95%Color and Shape:PowderMolecular weight:191.19 g/mol5-Methoxy-2-[[(4-Chloro-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-5-methoxy-1H-benzimidazole

CAS:<p>Omeprazole is a drug that belongs to the class of benzimidazole compounds. It is an inhibitor of gastric acid secretion in the stomach, reducing the production of hydrochloric acid and pepsin. Omeprazole has been shown to have greater chemical stability than other proton pump inhibitors (PPIs), with a higher solubility in water and a longer shelf life. Omeprazole also has anti-inflammatory properties, which may be due to its inhibition of prostaglandin synthesis. Omeprazole also exhibits pharmacokinetic properties that are different from other PPIs. Omeprazole is rapidly absorbed following oral administration and has a high bioavailability, which can be attributed to its hydroxyl group. This hydroxyl group allows for esomeprazole (a prodrug) to be formed by hydrolysis in the gut or liver, increasing omeprazole's absorption and bioavailability.</p>Formula:C17H19N3O2SPurity:Min. 95%Color and Shape:PowderMolecular weight:329.42 g/mol5-Methoxy-2-[[(3,5-dimethyl-2-pyridinyl)methyl]sulphinyl]-1H-benzimidazole
