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 suppresses the production of stomach acid by blocking the H+/K+ ATPase enzyme. It is used for the treatment of gastroesophageal reflux disease, peptic ulcers, and Zollinger-Ellison syndrome. Rabeprazole has been shown to be more effective than omeprazole in reducing gastric acid secretion in two-way crossover studies. Rabeprazole also has been shown to inhibit the growth of antibiotic-resistant strains of bacteria. In addition, rabeprazole binds to metal ions like iron and copper, which may affect its pharmacokinetics and efficacy. This drug is currently being investigated as an analytical method for determination of proton pump inhibitors in human serum and urine samples by electrochemical impedance spectroscopy (EIS).</p>Formula:C18H21N3O3SPurity:Min. 95%Color and Shape:White PowderMolecular weight:359.44 g/molAlbendazole sulfoxide
CAS:<p>Albendazole sulfoxide is a sulfoxide of albendazole. The molecular docking analysis of the two molecules showed that the sulfoxide group is located in the same position as the hydroxyl group on albendazole. It has been shown that this replacement of hydroxyl with a sulfoxide group increases the solubility and stability of albendazole, which may be due to hydrogen bonding interactions between these groups. Albendazole sulfoxide has been shown to be an effective treatment for infections caused by parasites such as helminths. However, it should not be used in combination with drugs that are metabolized by cytochrome P450 enzymes because it can inhibit their activity.</p>Formula:C12H15N3O3SPurity:Min. 97 Area-%Color and Shape:White PowderMolecular weight:281.33 g/molLansoprazole N-oxide

CAS:<p>5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole N-oxide is an ammonium salt of a sulfoxide with a chloride. It is also known as esomeprazole magnesium. This drug is used in the preparation of pharmaceutical preparations and is used to treat gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions. The magnesium salt form is a polymorphic substance that has a crystalline form that occurs in nature, called alpha form, and a synthetic form that occurs in laboratory experiments and has been designated beta form. The alpha form exhibits enantioselectivity when it binds to the enzyme pepsin, which causes the drug to have an antiulcer effect.</p>Formula:C17H19N3O4SPurity:Min. 95%Color and Shape:PowderMolecular weight:361.42 g/mol5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]thio]-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/mol2-(3-(1-Benzylpiperidin-4-yl)-2-oxopropyl)-4,5-dimethoxybenzoic acid sodium salt
