Misuse or overuse of antibiotics can have a variety of detrimental microbial effects. However, the body burden of antibiotics in the general population is currently unclear. In this cross-sectional study, we determined four classes of widely-applied antibiotics (3 imidazoles, 2 sulfonamides, 5 quinolones, and 2 chloramphenicols) in urine samples from 1170 adult residents in Shenzhen, China. Antibiotics were detected in 30.8% of all urine samples with concentrations ranging from <LOD to 3517μg/mL, among which metronidazole, ofloxacin and florfenicol were predominant. Notably, antibiotics prohibited for human or veterinary use were detected in 21.0% of samples, indicating that these antibiotics may still be overused in daily life. We found that the presence of antibiotics in urine is associated with being overweight (OR: 1.386, 95% CI: 1.056-1.819, p = 0.019) and obesity (OR: 1.862, 95% CI: 1.103-3.146, p = 0.020) in the adult population. Multilinear regression anal. showed that a percent increase of hydroxy metronidazole was related to 9.86% pos. change of body mass index (p = 0.029). Interestingly, we also found total antibiotic concentration higher in the unmarried group (p = 0.006). Besides, consumption of smoked foods was correlated with urinary antibiotic levels (p = 0.001), indicating smoked meat may be a potential exposure source of veterinary antibiotics. These results highlight the need to reduce human exposure to banned antibiotics. Future research could focus on assessing the health risk and other outcomes of antibiotic overuse. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Related Products of 70458-96-7).
1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Related Products of 70458-96-7
