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.

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/mol3-Amino-6-(2,3-dichlorophenyl)-1,2,4-triazin-5(4H)-one

CAS:Controlled Product<p>N-Desmethyl galanthamine is a plant alkaloid that is found in the Huperzia serrata plant. It has been shown to have cholinergic activity and calcium binding properties. N-Desmethyl galanthamine inhibits acetylcholinesterase, an enzyme responsible for the breakdown of acetylcholine, which is a neurotransmitter. This inhibition leads to increased levels of acetylcholine, which results in increased neuron stimulation and improved memory function. N-Desmethyl galanthamine also binds to β2 nicotinic receptor sites and blocks the binding of nicotine, leading to decreased nicotine dependence.</p>Formula:C16H19NO3Purity:Min. 95%Molecular weight:273.33 g/mol(R)-5-Hydroxymethyl tolterodine
CAS:<p>(R)-5-Hydroxymethyl tolterodine is a prodrug that is metabolized by cytochrome P450 3A4 (CYP3A4) in the liver to its active form, tolterodine. This drug can be used as an alternative for gabapentin in the treatment of detrusor muscle overactivity associated with neurogenic bladder dysfunction. The pharmacokinetic properties of (R)-5-hydroxymethyl tolterodine are similar to those of gabapentin, including the elimination half-life and volume of distribution. However, unlike gabapentin, which has been shown to increase the glomerular filtration rate (GFR) and renal blood flow, there is no evidence that this drug has any effect on GFR or renal blood flow.

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/molDi-2-thienylmethanone

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.

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).
