Insights into Receptor Function and New Drug Development Targets (Research and Perspectives in Endocrine Interactions) - Hardcover

Von der hinteren Coverseite

G-Protein Coupled receptors (GPCRs) and other receptors are significant targets for drug discovery, due to their roles in fundamental physiological processes. Among these roles are: regulation of growth, food intake, reproduction, water balance, sensory perception, blood pressure and heart rate. GPCR-directed drugs account for approximately $40 billion in sales and, of drugs at market, approximately 70% target GPCR function.

The availability of combinatorial chemistry coupled with high throughput screening techniques have facilitated discovery of peptidic and non-peptidic ligands of membrane receptors. Mutant receptor models have revealed their role in health and disease and provided insight to new therapeutic approaches, based on control of protein trafficking. Understanding receptor-receptor interactions has provided one mechanism for receptor cross-talk and revealed unexpected interactions.

The completion of the human genome has identified a new source of therapeutic targets: "orphan receptors" with unknown functions and yet-to-be discovered ligands. Some orphans have now been identified as ghrelin, nociceptin, apelin, and urocortin. This finding, along with important technologies to develop ligands with desirable characteristics, including peptidomimetics is likely to further accelerate interest in this area.
