Affinity determination is a crucial step of an antibody characterization. Here, we describe a method for antibody affinity determination by flow cytometry, relying on the unique affinity of biotin for streptavidin for easy and efficient antibody labeling. Several labeling approaches are described and discussed in this chapter, including chemical and enzymatic (in vivo and in vitro) biotinylation. Finally, a procedure for K (D) determination by flow cytometry is precisely described.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.

The inhibition of acetylcholinesterase (AChE), an enzyme responsible for the inactivation and decrease in acetylcholine in the cholinergic pathway, has been considered an attractive target for small-molecule drug discovery in Alzheimer's disease (AD) therapy. In the present study, a series of TZD derivatives were designed, synthesized, and studied for drug likeness, blood-brain barrier (BBB) permeability, and adsorption, distribution, metabolism, excretion, and toxicity (ADMET). Additionally, docking studies of the designed compounds were performed on AChE.

Binuclear ruthenium complexes have been investigated for potential DNA-targeted therapeutic and diagnostic applications. Studies of DNA threading intercalation, in which DNA base pairs must be broken for intercalation, have revealed means of optimizing a model binuclear ruthenium complex to obtain reversible DNA-ligand assemblies with the desired properties of high affinity and slow kinetics. Here, we used single-molecule force spectroscopy to study a binuclear ruthenium complex with a longer semi-rigid linker relative to the model complex.

Cenobamate is a new and highly effective antiseizure compound used for the treatment of adults with focal onset seizures and particularly for epilepsy resistant to other antiepileptic drugs. It acts on multiple targets, as it is a positive allosteric activator of γ-aminobutyric acid type A (GABA) receptors and an inhibitor of neuronal sodium channels, particularly of the late or persistent Na current. We recently evidenced the inhibitory effects of cenobamate on the peak and late current component of the human cardiac isoform hNav1.

Understanding drug-target interactions is crucial for identifying novel lead compounds, enhancing efficacy, and reducing toxicity. Phenotype-based approaches, like analyzing drug-induced gene expression changes, have shown effectiveness in drug discovery and precision medicine. However, experimentally determining gene expression for all relevant chemicals is impractical, limiting large-scale gene expression-based screening.
