Metabolic Studies of Drug Candidates for Neurological Disorders and Asthma Based on GABA_A Receptor Subtype Selective Ligands using Mass Spectrometry (312KB)

Development of pre-clinical experimental models to understand the in vivo metabolic performance of a drug is important in the field of drug discovery. In the present study, an in vitro microsomal assay was designed to evaluate the metabolic stability of GABAA receptor subtype selective ligands using microsomes and S9 fractions of human and mouse liver extracts. A LC-MS/MS method was developed to quantify the amount of drug degrading over a period of time using verapamil as internal standard.

The Challenge of Discovery and Development of Pharmaceutical Products Using Imaging Mass Spectrometry: iMScope TRIO (182KB)

Imaging mass spectrometry (IMS), which uses MALDI-TOF/MS analysis to identify the presence of target substances in biosamples such as tissue samples, is a cutting-edge measurement technology that is becoming increasingly popular in medical and biological research. We sat down with Hidefumi Kaji, PhD, of Mitsubishi Tanabe Pharma Corporation’s DMPK (Drug Metabolism and Pharmacokinetics) Research Laboratories Research Division, and asked him about his use of this technology.

Utility of High-resolution MALDI imaging in Drug Discovery: Histological Distribution of Gentamicin in Proximal Renal Tubules of Rats (556KB)

MS/MS imaging of gentamicin was performed from high-selectivity analysis of endogenous metabolites in biological tissue.High-resolution (10 μm) imaging of rat renal cortex showed that gentamicin is specifically distributed in proximal renal tubules. A new matrix application method is useful for sensitive MALDI imaging.
