Abstract
G-protein coupled receptors (GPCRs) mediate a large number of biological pathways and are major therapeutic targets. One of the most exiting phenomena of GPCRs is their ability to interact with other GPCRs. GPCRGPCR interactions, also known as GPCR oligomerization, may create various functional entities such as homo- and heterodimers and also form complex multimeric GPCR clusters. In many biological systems, GPCR-GPCR interactions are crucial for signal regulation. The interaction with other receptors results in allosteric modifications of GPCRs through conformational changes. Allosteric inhibition of GPCRs is considered an attractive strategy for drug development and does not involve targeting the orthosteric site. Understanding the nature of GPCR-GPCR interactions is mandatory for developing allosteric inhibitors. Studying GPCR-GPCR interactions is a challenging task and many methods have been developed to analyze these events. This review will highlight some of the methods developed to study GPCR-GPCR interactions and will describe pivotal studies that provided the basic understanding of the importance of GPCR oligomerization. We will also describe the significance of GPCR interaction networks for drug development. Recent studies will be reviewed to illustrate the use of state-of-the-art biophysical and spectroscopic methods for the discovery of GPCR oligomerization modulators.

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
