Factors influencing the Central Nervous System (CNS) distribution of the ATR inhibitor elimusertib (BAY1895344): Implications for the treatment of CNS tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

GBM has a poor prognosis despite aggressive treatment, in part due to lack of adequate drug permeability at the BBB. CNS distribution of elimusertib is partially limited by P-gp efflux at the BBB, and high binding to CNS tissues leads to low levels of pharmacologically active (unbound) drug in the brain.

Preclinical systemic pharmacokinetics, dose-proportionality, and CNS distribution of the ATM inhibitor WSD0628, a novel radiosensitizer for the treatment of brain tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

Radiation therapy, a standard treatment option for many cancer patients, induces DNA double strand breaks (DSBs), leading to cell death. Efficacy of radiosensitizers for brain tumors may be influenced by a lack of effective drug delivery across the blood-brain barrier (BBB).

Pharmacokinetics of panobinostat: Inter-species difference in metabolic stability [Metabolism, Transport, and Pharmacogenetics]

ASPET

Panobinostat is a potent pan-HDAC inhibitor that has been tested in multiple studies for the treatment of brain tumors. There have been contrasting views surrounding its efficacy for the treatment of tumors in the CNS following systemic administration when examined in different models or species.

Humanization of SLCO2B1 in rats increases rCYP3A1 protein expression but not the metabolism of erlotinib to OSI-420 [Metabolism, Transport, and Pharmacogenetics]

ASPET

A first pharmacological phenotyping with the OATP2B1 substrate-drug atorvastatin revealed reduced hepatic content and increased expression of rCYP3A1 in the humanized animals. The contrary was observed, when microsomes isolated from treatment naive animals were assessed for the OSI-420 formation after erlotinib exposure.

Open Targets Platform 23.12 has been released!

The Open Targets Blog

Target prioritisation A major new feature of this release is the Target Prioritisation view, which provides an assessment of target-specific properties of interest when evaluating the suitability of a target for a drug discovery programme. It is presented here with an additional layer of analysis with a drug discovery focus.
