| Outline of Final Research Achievements |
Organic cation transporters (OCTs) are involved in hepatic and renal distribution of various substrates, and may be primarily involved in pharmacokinetics of some substrate drugs. The aim of the present study is to search endogenous OCTs substrates. According to the untargeted metabolome analysis, plasma concentration of some acylcarnitines in OCT’s inhibitors treated mice were higher than that in vehicle-treated mice. Efflux of acetylcarnitine was also observed in from oocytes expressing OCT1. Thus, acylcarnitines were presumably endogenous OCT1 substrates although the role of OCTs in their tissue distribution should be further evaluated.
