Pilocarpine is a cholinergic agonist that is metabolized to pilocarpic acid by serum esterase. In this study, we discovered a novel metabolite in human urine after the oral administration of pilocarpine hydrochloride, and we investigated the metabolic enzyme responsible for the metabolite formation. The structure of the metabolite was identified as 3-hydroxypilocarpine by liquid chromatography-...

Iguratimod is a new synthetic disease-modifying antirheumatic drug intended to treat patients with rheumatoid arthritis. A new method using recombinant human CYP450s yeast cells containing c-DNA expressed P450s was applied to identify the metabolic pathways of iguratimod and to prepare its metabolite. The metabolite was isolated, and its structure was identified by quadrupole time-of-flight-mas...

Background: To determine the atmospheric contamination by pesticides, conducting laboratory studies is necessary before operating field studies. The aim of this research study was to develop an analytical method to sample and simultaneously determine airborne amitraz and its metabolite. Methods: A modified fritted impinger with acetonitrile as the liquid sorbent was used in order to study the...
