    Abstract Cystic fibrosis (CF) is an autosomal recessive disease resulting from mutations on both copies of the CFTR gene. Phenylalanine deletion at position 508 of the CFTR protein (F508del-CFTR) is the most frequent mutation in CF patients. Currently, the most effective treatments of CF use a dual or triple combination of CFTR correctors and potentiators. In triple therapy, two correctors (C1 and C2) and a potentiator are employed. Herein, we describe the identification and exploration of the SAR of a series of 4-aminopyrrolidine-2-carboxylic acid C2 correctors of CFTR to be used in conjunction with our existing C1 corrector series for the treatment of CF.

    Abstract The hallucinogenic plant Salvia divinorum (i.e., "magic mint") is a member of the Sage family that has been used for divination and shamanism by the Mazatecs. Over the past decade or so, S. divinorum has been increasingly used recreationally. The neoclerodane diterpene salvinorin A is the active component of S. divinorum, and recently, the kappa opioid receptor (KOR) has been identified, in vitro and in vivo, as its molecular target. The discovery of KOR as the molecular target of salvinorin A has opened up many opportunities for drug discovery and drug development for a number of psychiatric and non-psychiatric disorders.

    Abstract An estimated 50% of currently marketed drugs target G protein-coupled receptors (GPCRs) for a wide variety of indications, including central nervous system (CNS) disorders. Although drug discovery efforts have focused on GPCRs, less than 10% of GPCRs are currently used as drug targets. Thus, GPCRs continue to represent a significant opportunity for future CNS drug development. Identifying the molecular targets of psychoactive compounds may result in the elucidation of novel targets for CNS drug discovery. This commentary will describe discovery-based approaches and provide several recent examples of novel ligand-receptor interactions discovered through systematic screening of the 'receptorome'.

    Abstract Acute activation of Galpha(i/o)-coupled D2 dopamine receptors inhibits A2A adenosine receptor stimulation of adenylate cyclase. This antagonistic interaction between D2 dopamine and A2A adenosine receptors has been well documented; however, the effects of persistent activation of D2 dopamine receptors on subsequent A2A adenosine receptor signaling have not been explored. The present study investigated the effects of short-term (3-h) and long-term (18-h) activation of D2L dopamine receptors on subsequent A2A adenosine receptor stimulation of adenylate cyclase in CAD-D2L and NS20Y-D2L neuroblastoma cells. Short- and long-term activation of D2L dopamine receptors markedly increased 5'-N-methylcarboxamidoadenosine (MECA)-stimulated cyclic AMP accumulation 1.4-fold and 1.7-fold, respectively. D2L receptor-induced sensitization of A2A-stimulated cyclic AMP accumulation was blocked by the D2 antagonist spiperone and pertussis toxin pretreatment. In addition, persistent activation of A2A adenosine receptors resulted in 50% desensitization of subsequent MECA-stimulated cyclic AMP accumulation; however, MECA-induced desensitization of A2A adenosine receptors did not prevent completely quinpirole-induced sensitization of adenylate cyclase. These studies revealed a novel mode of regulation between D2L dopamine and A2A adenosine receptors and suggest a cooperative interaction in the regulation of cyclic AMP signaling.

    Abstract Cystic fibrosis (CF) is a multiorgan disease of the lungs, sinuses, pancreas, and gastrointestinal tract that is caused by a dysfunction or deficiency of the cystic fibrosis transmembrane conductance regulator (CFTR) protein, an epithelial anion channel that regulates salt and water balance in the tissues in which it is expressed. To effectively treat the most prevalent patient population (F508del mutation), two biomolecular modulators are required: correctors to increase CFTR levels at the cell surface, and potentiators to allow the effective opening of the CFTR channel. Despite approved potentiator and potentiator/corrector combination therapies, there remains a high need to develop more potent and efficacious correctors. Herein, we disclose the discovery of a highly potent series of CFTR correctors and the structure-activity relationship (SAR) studies that guided the discovery of ABBV/GLPG-2222 (22), which is currently in clinical trials in patients harboring the F508del CFTR mutation on at least one allele.

    Abstract Salvinorin A, the active component of the hallucinogenic sage Salvia divinorum, is an apparently selective and highly potent kappa-opioid receptor (KOR) agonist. Salvinorin A is unique among ligands for peptidergic G protein-coupled receptors in being nonnitrogenous and lipid-like in character. To examine the molecular basis for the subtype-selective binding of salvinorin A, we utilized an integrated approach using chimeric opioid receptors, site-directed mutagenesis, the substituted cysteine accessibility method, and molecular modeling and dynamics studies. We discovered that helix 2 is required for salvinorin A binding to KOR and that two residues (Val-108(2.53) and Val-118(2.63)) confer subtype selectivity. Intriguingly, molecular modeling studies predicted that these loci exhibit an indirect effect on salvinorin A binding, presumably through rotation of helix 2. Significantly, and in agreement with our in silico predictions, substituted cysteine accessibility method analysis of helix 2 comparing KOR and the delta-opioid receptor, which has negligible affinity for salvinorin A, revealed that residues known to be important for salvinorin A binding exhibit a differential pattern of water accessibility. These findings imply that differences in the helical orientation of helix 2 are critical for the selectivity of salvinorin A binding to KOR and provide a structurally novel basis for ligand selectivity.
