The pharmacogenomics (PGx) testing becomes of great opportunity for physicians to make the proper decision regarding each non-trivial patient that does not respond to therapy. Although pharmacogenomics has become of growing interest to the healthcare market during the past five to ten years the exact mechanisms linking the genetic polymorphisms and observable responses to drug therapy are not always clear. Therefore, the success of PGx testing depends on the physician’s ability to understand the obtained results in a standardized way for each particular patient.

  • Measuring Ligand Efficacy at the Mu- Opioid Receptor Using A
    RESEARCH ARTICLE Measuring ligand efficacy at the mu- opioid receptor using a conformational biosensor Kathryn E Livingston1,2, Jacob P Mahoney1,2, Aashish Manglik3, Roger K Sunahara4, John R Traynor1,2* 1Department of Pharmacology, University of Michigan Medical School, Ann Arbor, United States; 2Edward F Domino Research Center, University of Michigan, Ann Arbor, United States; 3Department of Pharmaceutical Chemistry, School of Pharmacy, University of California San Francisco, San Francisco, United States; 4Department of Pharmacology, University of California San Diego School of Medicine, La Jolla, United States Abstract The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects. Here, we present a direct way to quantify the efficacy of ligands by measuring the binding of a R*-specific biosensor to purified receptor employing interferometry. As an example, we use the mu-opioid receptor (m-OR), a prototypic class A GPCR, and its active state sensor, nanobody-39 (Nb39). We demonstrate that ligands vary in their ability to recruit Nb39 to m- OR and describe methadone, loperamide, and PZM21 as ligands that support unique R* conformation(s) of m-OR. We further show that positive allosteric modulators of m-OR promote formation of R* in addition to enhancing promotion by orthosteric agonists. Finally, we demonstrate that the technique can be utilized with heterotrimeric G protein. The method is cell- free, signal transduction-independent and is generally applicable to GPCRs.

  • Understanding Key Determinants of Drug Activity
    CASE STUDY Dr. Kevin Lustig, President and CEO, The Assay Depot, Inc. Greater San Diego Area Understanding Key Determinants of Drug Activity SUMMARY This article highlights the increasing role that drug metabolism and transport proteins have in the drug approval process. CASE STUDY: The Assay Depot, Inc. The dynamics of drug metabolizing enzymes and transporters is critical to the development of personalized medicine strategies. Abstract / Summary The dynamics of drug metabolizing enzymes and transporters is critical to the develop- ment of personalized medicine strategies. A multitude of factors regulate enzymes and transporters, which in turn affect the pharmacokinetic properties of drugs and medi- ate drug interactions. Evaluation of drug interaction profiles is a critical step in drug development and necessitates detailed in vitro and in vivo studies along with predictive modeling. PharmaPendium® via its Metabolizing Enzymes and Transporters Module provides unprecedented depth of data on drug metabolizing enzymes and transporters and offers a unique platform for modeling advanced drug interactions. This Module will prove to be a valuable resource capable of improving workflows and accelerating devel- opment by enabling intelligent, in silico drug design. By providing scientists with all of the available knowledge about drug metabolism, we can significantly reduce the need for costly and time-consuming lab work and animal models. Requiring these only to answer the true unknowns where no one else has gone before.
