Gタンパク質結合受容体 (GPCR)：技術概要、新興技術、市場トレンドと機会 (第2版)

Abstract

G Protein-Coupled Receptors (GPCRs) account for 50% of the current drug targets, and remain about one-third of the drug discovery effort in the drug discovery-development community. As a result of the sequencing of the human genome, more than 150 orphan and non-chemosensory GPCRs have been identified for which their cognate ligands or biological functions are unknown. De-orphanization of those receptors could bring novel therapeutic targets to the industry against which novel therapeutics could be designed. In addition, current GPCR-based drugs only target ~30% of the approximately 200 known GPCRs in the genome. This is a rich target class that is highly-druggable.This Report will benefit those companies, institutions, and individuals requiring an in-depth and thorough analysis of the technical areas in GPCRs, the emerging technologies in this space, as well as qualitative and quantitative market analyses, trends, and attendant business opportunities. Further, this Report provides thorough profiles of those companies currently active within the GPCR space.
