Kirchmeier, R. L.; Upton, R. P. published an article in 1978, the title of the article was Simultaneous determination of vancomycin, anisomycin, and trimethoprim lactate by high pressure liquid chromatography.Category: pyrimidines And the article contains the following content:

A reverse phase, high pressure liquid chromatog. method for the rapid, accurate, precise, and simultaneous determination of vancomycin [1404-90-6], anisomycin [22862-76-6], and trimethoprim lactate [23256-42-0] was developed, and applied to the determination of these compounds in antibiotic mixtures No chem. methods for the determination of anisomycin have previously been reported. The methods reported in the literature for the determination of vancomycin, and/or trimethoprim lactate are imprecise, nonspecific, or time consuming, and do not allow the simultaneous quant. of anisomycin, vancomycin, and trimethoprim. Precision of the high pressure liquid chromatog. assay was found to be ±1.8%, ±1.1%, and ±2.2% for vancomycin, anisomycin, and trimethoprim lactate, resp. (two standard deviations relative to the average). The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).Category: pyrimidines

On June 30, 1981, Lees, G. M.; Percy, W. H. published an article.COA of Formula: C17H24N4O6 The title of the article was Antibiotic-associated colitis: an in vitro investigation of the effects of antibiotics on intestinal motility. And the article contained the following:

Ampicillin Na [69-52-3] (1-800 μg/mL), doxycycline-HCl [10592-13-9] (1-20 μg/mL), mecillinam-HCl [32887-08-4] (1-800 μg/mL), and metronidazole [443-48-1] (0.5-200 μg/mL) did not affect intestinal motility in vitro in guinea pig ileum and rabbit colon. Clindamycin-HCl (I) [21462-39-5] (0.05-500 μg/mL), gentamicin sulfate (II) [1405-41-0] (5 μg-1 mg/mL), kanamycin sulfate (III) [25389-94-0] (0.025-500 μg/mL), pivmecillinam-HCl (IV) [32887-03-9] (1-20 μg/mL), and trimethoprim lactate (V) [23256-42-0] (5-200 μg/mL) all inhibited evoked and reflex responses of the guinea pig ileum, but only I and V also affected evoked responses of the rabbit colon. II and III appeared to have a predominantly prejunctional action, IV and V a predominantly postjunctional action; I had a prejunctional action at low concentrations and long exposure times, and a postjunctional action at high concentrations and short exposure times. The concentration of each antibiotic required to inhibit the peristaltic reflex of the guinea pig ileum was less than that required to inhibit its responses to elec. stimulation or exogenous acetylcholine or histamine but greater than the serum levels associated with their resp. use in therapeutic doses. A hypothesis is proposed whereby antibiotic-induced alterations in gastrointestinal motility could lead to the development of pseudomembranous colitis. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).COA of Formula: C17H24N4O6

On April 30, 1980, Melby, Kjetil; Midtvedt, Tore published an article.Formula: C17H24N4O6 The title of the article was Effects of some antibacterial agents on the phagocytosis of phosphorus-32-labeled Escherichia coli by human polymorphonuclear cells. And the article contained the following:

Gentamicin [1403-66-3], trimethoprim lactate [23256-42-0] cephalothin [153-61-7], colistin [1066-17-7], erythromycin [114-07-8], oxytetracycline [79-57-2], and chloramphenicol [56-75-7] were studied in a phagocytic system. A radiolabeled strain of E. coli was used as test bacterium and human polymorphonuclear cells were used as phagocytes. Except for trimethoprim and cephalothin, there was a tendency towards depression of the process of phagocytosis in the presence of high concentrations of the various antibiotics. Colistin in a high concentration (83 μg/mL) exerted the most significant effect. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).Formula: C17H24N4O6

Vaz, C. S. L.; Voss-Rech, D.; Pozza, J. S.; Coldebella, A.; Silva, V. S. published an article in 2014, the title of the article was Isolation of Campylobacter from Brazilian broiler flocks using different culturing procedures.Application In Synthesis of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate And the article contains the following content:

Conventional culturing methods enable the detection of Campylobacter in broiler flocks. However, laboratory culture of Campylobacter is laborious because of its fastidious behavior and the presence of competing nontarget bacteria. This study evaluated different protocols to isolate Campylobacter from broiler litter, feces, and cloacal and drag swabs. Samples taken from com. Brazilian broiler flocks were directly streaked onto Preston agar (PA), Campy-Line agar (CLA), and modified charcoal cefoperazone deoxycholate agar (mCCDA) and also enriched in blood-free Bolton broth (bfBB) for 24 and 48 h followed by plating onto the different selective media. Higher numbers of Campylobacter-pos. cloacal and drag swab samples were observed using either direct plating or enrichment for 24 h before plating onto PA, compared with enrichment for 48 h (P < 0.05). Furthermore, direct plating was a more sensitive method to detect Campylobacter in broiler litter and feces samples. Anal. of directly plated samples revealed that higher Campylobacter levels were detected in feces streaked onto PA (88.8%), cloacal swabs plated onto mCCDA (72.2%), drag swabs streaked onto CLA or mCCDA (69.4%), and litter samples inoculated onto PA (63.8%). Preston agar was the best agar to isolate Campylobacter from directly plated litter samples (P < 0.05), but there was no difference in the efficacies of PA, mCCDA, and CLA in detecting Campylobacter in other samples. The isolated Campylobacter strains were phenotypically identified as Campylobacter jejuni or Campylobacter coli. The predominant contaminant observed in the Campylobacter cultures was Proteus mirabilis, which was resistant to the majority of antimicrobial agents in selective media. Together, these data showed that direct plating onto PA and onto either CLA or mCCDA as the second selective agar enabled the reliable isolation of thermophilic Campylobacter species from broiler samples. Finally, Campylobacter was detected in all broiler flocks sampled. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).Application In Synthesis of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate
