Abstract
P-glycoprotein (P-gp) is a drug efflux transporter with broad substrate specificity localized in the blood-brain barrier and in several peripheral organs. In order to understand the role of P-gp in physiological and patho-physiological conditions, several carbon-11 labelled P-gp tracers have been developed and validated. This review provides an overview of the spectrum of radiopharmaceuticals that is available for this purpose. A short overview of the physiology of the blood-brain barrier in health and disease is also provided. Tracer kinetic modelling for quantitative analysis of P-gp function and expression is highlighted, and the advantages and disadvantages of the various tracers are discussed.

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

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
