Amoxicillin Amoxicillin is a penicillin antibiotic. It fights bacteria in your body. Amoxicillin is used to treat many different types of infections caused by bacteria‚ such as ear infections‚ bladder infections‚ pneumonia‚ gonorrhea‚ and E. coli or salmonella infection. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer

recently‚ we have suggested an alternative structure for the product obtained by the reaction of thiourea with chloroacetylchloride (3). The structure of the product is found to have the 2-imino-4-thiazolidinones moiety (3) and not the thiohydantoin as has been reported previously by another group (4).
