Physiologically‐Based Pharmacokinetic Modeling of the PARP Inhibitor Niraparib

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 1, January 2026.
ABSTRACT A physiologically‐based pharmacokinetic (PBPK) model of niraparib and its primary metabolite using a relevant virtual cancer population is reported here. A series of in vitro experiments using liver S9, microsomes, and hepatocytes with various inhibitors and recombinant supersomes demonstrated that niraparib is specifically metabolized by ...

Photocatalytic Reduction of Nitroaromatic Compounds Using NiO‐Modified MgAl Hydrotalcite: A Sustainable Approach for Wastewater Treatment

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The growing industrialization has caused the generation of highly toxic compounds such as nitroaromatic compounds. An adequate treatment to reduce the contamination of these organic compounds is necessary. The photocatalytic reduction of aromatic compounds using semiconductor materials favors the production of nitroaromatics.
