Self-docking and cross-docking simulations of G protein-coupled receptor-ligand complexes: Impact of ligand type and receptor activation state G protein-coupled receptors (GPCR) are the largest family Ligand discovery aimed at identification of chemical tools and drug leads is aided by molecular docking Likewise, the relative importance of receptor activation state and ligand function differences have also after ligand placement.

Humanity has always sought to live longer and for this, multiple strategies have been tried with varying In this sense, G protein-coupled receptors (GPCRs) may be a good option to try to prolong our life while this way, we present the analysis of a series of GPCRs whose activity has been shown to affect the lifespan Our compilation of data revealed that the mechanisms most involved in the role of GPCRs in lifespan are antagonist drugs, depending on the beneficial or harmful effects of each GPCR, in order to prolong people's lifespan

October 2022 "The role of different G protein-coupled receptors (GPCRs) in the cardiovascular system is well understood in cardiomyocytes and vascular smooth muscle cells (VSMCs). In the former, stimulation of Gs-coupled receptors leads to increases in contractility, whereas stimulation of Gq-coupled receptors modulates cellular survival and hypertrophic responses. In VSMCs, stimulation of GPCRs also modulates contractile and cell growth phenotypes. Here, we will focus on the relatively less well-studied effects of GPCRs in cardiac fibroblasts, focusing on key signaling events involved in the activation and differentiation of these cells. We also review the hierarchy of signaling events driving the fibrotic response and the communications between fibroblasts and other cells in the heart. We discuss how such events may be distinct depending on where the GPCRs and their associated signaling machinery are localized in these cells with an emphasis on nuclear membrane-localized receptors. Finally, we explore what such connections between the cell surface and nuclear GPCR signaling might mean for cardiac fibrosis." Read more at the source #DrGPCR #GPCR #IndustryNews

November 2021 "Target class-specific libraries mean you need to screen less to identify high-quality Antibody developers are increasingly utilising antibody libraries to derive high-quality, drug-like biologics As a result, most approved library-derived antibodies originate from just three libraries. To target hard-to-drug targets like G protein-coupled receptors (GPCRs), more libraries, including better and more targeted libraries, are needed."

January 2022 "G-protein-coupled receptors’ star has been on the rise in biotech in recent years as researchers have discovered the vast potential for GPCR-targeting drugs in treating a range of health conditions, from cancer and genetic disorders to inflammation and metabolic imbalances. Among those hitching their wagons to that star are Verily and Sosei Heptares , which have struck a research agreement to discover new GPCR targets that’ll fuel the development of potential drug candidates. The financial details of the strategic collaboration weren’t released, but Sosei Heptares ’ past two team-ups in GPCR-based drug discovery have clocked in at $1 billion—with Genentech—and, just last November, $2.6 billion in a partnership with Neurocrine."

June 2022 "June 15, 2022 06:30 AM EDT - In 2016, Abbie Celniker was promoted to partner at Third Rock Ventures as the firm raised just over $600 million for its fourth fund. Since then, Celniker has helped usher in an additional fund and headed a few startups as interim CEO. Coming on its 15th year, Third Rock Ventures announced its sixth fund today — and largest one by far — at a whopping $1.1 billion. Adding it all up, Third Rock has raised $3.8 billion since its inception. That money has gone to some 60 biotechs, much of it as early funding." Read more at the source #DrGPCR #GPCR #IndustryNews

seven agonists to induce G protein, G protein-coupled receptor kinase 2 (GRK2), as well as arrestin3 binding In order to avoid interference between these interactions, we studied GRK2 binding in the presence of inhibitors of Gi and Gq proteins and analyzed arrestin3 binding to prestimulated M3 receptors to avoid the agonists for G protein- and GRK2-M3R interaction was the same, suggesting that G protein and GRK2 binding to M3R requires similar receptor conformations, whereas requirements for arrestin3 binding to M3R are

Radioligand binding assays revealed considerable binding of kurarinone on D1R, D2LR, and D4R. Molecular docking displayed low binding energies during the intermolecular interactions of kurarinone with the key residues of the deep orthosteric binding pocket and the extracellular loops of D1R, D2LR , and D4R, validating substantial binding affinities to these prime targets.
