As rifampicin can cause the induction and inhibition of multiple metabolizing enzymes and transporters, it has been challenging to accurately predict the complex drug–drug interactions (DDIs). We previously constructed a physiologically‐based pha

In human plasma, the main agent of hydrolysis of the ester-type prodrug of levodopa, designated ONO-2160, is alpha-1-acid glycoprotein (AGP), which is a mixture of the F1*S and A variants at molar ratios of 3:1 to 2:1. In this study, the mechanism of

1. Immunodeficient chimeric mice with humanised liver have been useful in predicting total clearance values of drugs in humans. However, their usefulness may currently be limited for specific compounds with interspecies differences.2. In vivo total c

ONO-2160 is a newly developed oral ester-type prodrug of levodopa for removing the problems in use of levodopa. It has a structure in which two of the same substituents are bound to levodopa. It is important to understand the pharmacokinetics and met

Previously, we found that ONO-2160, an ester-type prodrug of levodopa (3-hydroxy-l-tyrosine), was mainly hydrolyzed in human plasma by α1-acid glycoprotein (AGP) with a partial contribution of albumin. In this study, we investigated whether ONO-2160

This study aimed to construct a physiologically based pharmacokinetic (PBPK) model of rifampicin that can accurately and quantitatively predict complex drug-drug interactions (DDIs) involving its saturable hepatic uptake and auto-induction. Using in

The cause of nonlinear pharmacokinetics (PK) (more than dose-proportional increase in exposure) of a urea derivative under development (compound A: anionic compound [pKa: 4.4]; LogP: 6.5; and plasma protein binding: 99.95%) observed in a clinical tri

Brain microvascular endothelial cells (BMEC), together with astrocytes and pericytes, form the blood-brain barrier (BBB) that strictly restricts drug penetration into the brain. Therefore, in central nervous system drug development, the establishment
