Pharmacokinetics and toxicological studies how the body reacts to a specific administered substance, such as a drug, toxin, or food. Each substance experiences these four steps: absorption, distribution, metabolism, and excretion, which are the main parameters in pharmacokinetics studies. Many toxic endpoints exist. There are three main ways to measure toxicology and pharmacokinetic parameters: in vivo, in vitro, and in-silico. Knowing toxicological and pharmacokinetic parameters before developing a new drug candidate could save time and resources, as clinical studies are highly cost-demanding. This review aims to gather studies using in-silico methodologies to predict pharmacokinetic properties.

Background: Certain scientific publications suggest that medications with high protein binding, such as phenytoin, have lower-than-expected serum levels in patients receiving enteral nutrition (EN) preparations or nutritional supplements. Valproic acid (VPA) is highly protein bound but currently no interactions with EN that would reduce serum levels have been documented.
Case Description: A 69-year-old patient receiving enteral VPA oral solution via a nasojejunal tube experienced a clinically significant decrease in serum concentration when EN was initiated.

Bietti crystalline dystrophy (BCD) is an autosomal recessive disorder caused by loss-of-function mutations in the gene, characterized by crystal-like lipid deposits in the retina, progressive photoreceptor loss, and retinal pigment epithelium (RPE) deterioration. Currently, there are no approved treatments for BCD. VGR-R01, an investigational gene therapy, uses subretinal administration of recombinant adeno-associated virus type 8 (AAV8) vector to deliver the human CYP4V2 gene.

The global rise in antibiotic resistance demands the urgent development of new antibacterial agents. This study investigated the antibacterial potential of four synthesized methoxy and thiophene chalcone derivatives (designated 3a, 4a, 3b, and 4b) against clinically relevant bacterial pathogens. These compounds were prepared through Claisen-Schmidt condensation, while their chemical structures were verified through applying Fourier-transform infrared, mass spectrometry, H nuclear magnetic resonance (NMR), and C NMR.

Licochalcone A (LCA), a natural flavonoid with potent anti-inflammatory properties, has shown promise as a neuroprotective agent. However, its ability to cross the blood-brain barrier (BBB) and exert central effects remains underexplored. In this study, we demonstrate for the first time that LCA enhances cognitive function in a lipopolysaccharide (LPS)-induced neuroinflammatory mouse model and effectively penetrates the BBB.

Ingestible biosensors are a mix of advanced biomedical engineering, digital health and precision pharmacotherapy. These miniaturised electronic devices are encapsulated in biocompatible materials, which operate within gastrointestinal (GI) tract. This enables real-time monitoring of pharmacological and physiological parameters.
