Advanced disease modeling using organoids, self-organized three-dimensional (3D) cell culture models derived from stem cells, or MPS, models for culturing multiple cell types in a microfluidic device and capable of recapitulating a physiological 3D dynamic environment, can accurately replicate the complex functions of respiratory organs, thus making them valuable tools for elucidating the organ damages caused by viral respiratory infections and evaluating the efficacy of candidate drugs against them. Recently, a wide range of organoids and MPS have been developed to model the complex pathophysiology caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and assess therapeutic drugs.

Voclosporin is a substrate for P-glycoprotein and CYP3A4, and it has been evaluated for intestinal membrane permeability in human induced pluripotent stem cell-derived intestinal epithelial cells (hiPSC-IECs). The membrane permeability in hiPSC-IECs is integrated into the PBPK model for simulating permeability accurately. The PBPK model simulated the systemic PK profile in fasted state in human.

To detect unstable iminium ions using liquid chromatography-tandem mass spectrometry (LC-MS/MS), potassium cyanide was added to the reaction mixture as a trapping agent. Human liver and intestinal microsomes were incubated with nintedanib in the presence of NADPH to form two iminium ion metabolites on the piperazine ring. Their formation is strongly inhibited by ketoconazole, a potent cytochrome P450 (CYP) 3A4 inhibitor. Among the recombinant P450s, only CYP3A4 formed cyanide adducts.
