Ion pairing LC-MS/MS method for analysis of intracellular phosphorylated metabolites
Utami, Wahyu (2015) Ion pairing LC-MS/MS method for analysis of intracellular phosphorylated metabolites. PhD thesis, University of Nottingham.
Nucleoside analogues have been extensively used in medication. The nucleoside analogue cordycepin is the principal bioactive compound found in the caterpillar fungi (Cordyceps and Ophiocordyceps). It has been shown to have biological activity, including anti-inflammatory, immunomodulatory and anti-proliferative activity in many kinds of malignant cells. Intracellular drug interactions at the nucleotide level can be explained by understanding the intracellular metabolism of nucleoside analogues as well as their plasma metabolism since their efficacy of therapy or toxicity does not associate with the plasma level of nucleoside. Therefore, investigation of the metabolism of nucleoside analogues is required for a full understanding of their pharmacological activity and toxicity. For that reason, here an ion pairing LC-MS/MS method has been developed for quantitative analysis of the nucleoside analogue cordycepin and the metabolites and its application to cell culture, using in vitro and in vivo studies.
