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
