This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: G protein-coupled receptors (GPCRs) constitute the largest family of membrane receptors in the human genome and play important roles in both physiology and disease. One important property of GPCRs is biased signaling, whereby ligand engagement selectively activates a subset of signaling pathways. There is great interest in the therapeutic development of biased ligands for GPCRs given that they have the potential to selectively target downstream signaling pathways of interest and treat diseases more safe and effective manner. However, the complexity of the structural and signaling properties of GPCRs has presented many challenges in developing biased ligands. Here, we introduce a novel and generalizable high-throughput screening approach for discovering biased ligands for GPCRs. Biased ligands can stabilize distinct receptor conformations, which directly affect receptor interaction with intracellular signaling proteins, resulting in different downstream signaling outcomes. Our method integrates high-throughput screening and statistical modeling to examine large mutant protein libraries and infer the ligand-receptor binding conformation based on mutation statistical patterns. The inferred binding conformations allow for efficient identification of candidate biased ligands based on their different binding interactions with the receptor. We applied our computer-aided high-throughput screening approach to search for biased ligands targeting the Complement 5a Receptor, an important GPCR involved in the immune response and cancer. Importantly, we identified a variety of biased mutants with distinct signaling properties. In the future, we aim to apply our platform to other GPCRs and promote the study and therapeutic application of GPCR biased signaling.

Download or read book Virtual Screening written by Christoph Sotriffer and published by John Wiley & Sons. This book was released on 2011-03-31 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug discovery is all about finding small molecules that interact in a desired way with larger molecules, namely proteins and other macromolecules in the human body. If the three-dimensional structures of both the small and large molecule are known, their interaction can be tested by computer simulation with a reasonable degree of accuracy. Alternatively, if active ligands are already available, molecular similarity searches can be used to find new molecules. This virtual screening can even be applied to compounds that have yet to be synthesized, as opposed to "real" screening that requires cost- and labor-intensive laboratory testing with previously synthesized drug compounds. Unique in its focus on the end user, this is a real "how to" book that does not presuppose prior experience in virtual screening or a background in computational chemistry. It is both a desktop reference and practical guide to virtual screening applications in drug discovery, offering a comprehensive and up-to-date overview. Clearly divided into four major sections, the first provides a detailed description of the methods required for and applied in virtual screening, while the second discusses the most important challenges in order to improve the impact and success of this technique. The third and fourth, practical parts contain practical guidelines and several case studies covering the most important scenarios for new drug discovery, accompanied by general guidelines for the entire workflow of virtual screening studies. Throughout the text, medicinal chemists from academia, as well as from large and small pharmaceutical companies report on their experience and pass on priceless practical advice on how to make best use of these powerful methods.

Book excerpt: Since their discovery approximately 25 years ago, adenosine receptors have now emerged as important novel molecular targets in disease and drug discovery. These proteins play important roles in the entire spectrum of disease from inflammation to immune suppression. Because of their expression on a number of different cell types and in a number of different organ systems they play important roles in specific diseases, including asthma, rheumatoid arthritis, Parkinson’s disease, multiple sclerosis, Alzheimer’s disease, heart disease, stroke, cancer, sepsis, and obesity. As a result of intense investigations into understanding the molecular structures and pharmacology of these proteins, new molecules have been synthesized that have high specificity for these proteins and are now entering clinical trials. These molecules will define the next new classes of drugs for a number of diseases with unmet medical needs.
