Final answer:
The lab's goal is to use microbiological and analytical methods to quantify the parent caffeine compound, assess its metabolic stability, and identify metabolites.
Step-by-step explanation:
The goal of the laboratory exercise concerning the isolation of caffeine is to apply microbiological methods and analytical techniques to achieve multiple objectives. These objectives include the ability to quantify the remaining parent compound present within a given sample, estimate the metabolic stability of the compound, and to separate and identify any metabolites that have been generated as a result of metabolic processes.
Through chromatographic techniques such as High-Performance Liquid Chromatography (HPLC) with UltraViolet (UV) and Tandem Mass Spectrometry (MS/MS) detection, the lab aims to evaluate both the permeability of compounds through biological barriers like the blood-brain barrier (BBB) and their pharmacokinetic properties in vitro and in vivo. Such methods are integral for determining the suitability of new chemical entities (NCEs) for drug development by assessing their behavior within biological systems, as exemplified by Fortuna et al. and Lv et al. in their respective studies.
