Journal ArticleDOI
Influence of sex on propofol metabolism, a pilot study: implications for propofol anesthesia.
Irena Loryan,Marja Lindqvist,Inger Johansson,Masahiro Hiratsuka,Masahiro Hiratsuka,Ilse P. van der Heiden,Ron H.N. van Schaik,Jan G. Jakobsson,Magnus Ingelman-Sundberg +8 more
TL;DR: There was a pronounced effect of sex, a finding that indicates an important factor for the previously described sex difference in systemic clearance of propofol seen, and was supported by in vitro data showing similar variability of prop ofol 4-hydroxylation in liver microsomes.
Journal ArticleDOI
The brain slice method for studying drug distribution in the CNS
TL;DR: A detailed protocol for the rat and mouse brain slice methods is provided, with the aim of enabling simple, cost-effective profiling of compounds with diverse physicochemical properties, for estimation of target-site pharmacokinetics in the early drug discovery process and fundamental pharmacological studies.
Journal ArticleDOI
Mechanistic Understanding of Brain Drug Disposition to Optimize the Selection of Potential Neurotherapeutics in Drug Discovery
Irena Loryan,Vikash K. Sinha,Claire Mackie,Achiel Van Peer,Wilhelmus Drinkenburg,An Vermeulen,Denise Morrison,Mario Monshouwer,Donald Heald,Margareta Hammarlund-Udenaes +9 more
TL;DR: Integration of the neuroPK parameters with pharmacodynamic readouts demonstrated the value of the proposed approach in the evaluation of target engagement and NCE selection, thereby optimizing the routine of evaluation and selection of novel neurotherapeutics.
Journal ArticleDOI
Molecular Properties Determining Unbound Intracellular and Extracellular Brain Exposure of CNS Drug Candidates
Irena Loryan,Vikash K. Sinha,Claire Mackie,Achiel Van Peer,Wilhelmus Drinkenburg,An Vermeulen,Donald Heald,Margareta Hammarlund-Udenaes,Carola M. Wassvik +8 more
TL;DR: Interpretable molecular descriptors that significantly contribute to the three key neuropharmacokinetic properties related to BBB drug transport, intracellular accumulation, and binding and distribution in the brain for a set of 40 compounds were identified using partial least-squares analysis.
Journal ArticleDOI
In-depth neuropharmacokinetic analysis of antipsychotics based on a novel approach to estimate unbound target-site concentration in CNS regions: link to spatial receptor occupancy.
Irena Loryan,Erik Melander,M. Svensson,M. Payan,F. König,Britt Jansson,Margareta Hammarlund-Udenaes +6 more
TL;DR: The observed regional differences in BBB penetration may potentially be important factors contributing to variations in therapeutic effect and side effect profiles among antipsychotic drugs.
