Abstract
Most metal-based drugs are pro-drugs; therefore, it is essential that methods are developed to follow their speciation in biological fluids, cells and tissues. This will lead to both a better understanding of the factors that affect their efficacies and toxicities and, consequently, to the design of new and superior drugs. The use of X-ray absorption spectroscopy on bulk samples, and X-ray microprobe techniques on cells and tissues, provides unprecedented information on the biotransformations and biodistributions of metal-containing drugs that is required for a better understanding of their pharmacology. Here the methodologies that have been used on a range of metal- or metalloid-containing drugs and dietary supplements are reviewed, with an emphasis on research conducted within our group. In particular, applications of these techniques to anti-cancer, anti-diabetic, and anti-inflammatory drugs are discussed.
Keywords: Metal-containing drugs, anti-cancer drugs, anti-diabetic drugs and supplements, anti-inflammatory drugs, X-ray absorption spectroscopy, biotransformations, biodistributions, efficacy, complexes, glutathione complex, multiple-scattering contributions, ARSENIC, SELENIUM, XAS and SRIXE techniques

Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more

AI techniques are increasingly integrated and accelerating the drug discovery process. These developments have not only attracted the attention of academia and industry but also raised important questions regarding the selection ...read more
From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
