  Design, Synthesis, and Pharmacological Evaluation of Fluorescent and Biotinylated Antagonists of ρ₁ GABA_C Receptors

  摘要：

  The rho(1) GABA(C) receptor is a ligand-gated chloride ion channel that shows promise as a therapeutic target for myopia, sleep disorders, memory and learning facilitation, and anxiety-related disorders. As such, there is a need for molecular probes to understand the role GABA(C) receptors play in physiological and pathological processes. To date, no labeled (either radioactive or fluorescent) GABA(C) selective ligand has been developed that can act as a marker for GABA(C) receptor visualization and localization studies. Herein, we report a series of fluorescent ligands containing different-sized linkers and fluorophores based around (S)-4-ACPBPA [(4-aminocyclopenten-1-yl)-butylphosphinic acid], a selective GABA(C) antagonist. One of these conjugates, (S)-4-ACPBPA-C5-BODIPY (13), displayed moderate potency (IC50 = 58.61 mu M) and selectivity (>100 times) for rho(1) over alpha(1)beta(2)gamma(2L) GABA(A) receptors. These conjugates are novel lead agents for the development of more potent and selective fluorescent probes for studying the localization and function of GABA(C) receptors in living cells.

  Novel γ-Aminobutyric Acid ρ₁Receptor Antagonists; Synthesis, Pharmacological Activity and Structure−Activity Relationships

  摘要：

  gamma-Aminobutyric acid (GABA) analogues based on 4-amino-cyclopent-1-enyl phosphinic acid (34-42) and 3-aminocyclobutane phosphinic acids (51, 52, 56, 57) were investigated in order to obtain selective homomeric rho(1) GABA(C) receptor antagonists. The effect of the stereochemistry and phosphinic acid substituent of these compounds on potency and selectivity within the GABA receptor subtypes was investigated. Compounds of high potency at GABA(C) rho(1) receptors (36, K-B = 0.78 mu M) and selectivity greater than 100 times (41, K-B = 4.97 mu M) were obtained. The data obtained was analyzed along with the known set of GABA(C) rho(1) receptor-ligands, leading to the development of a pharmacophore model for this receptor, which can be used for in silico screening.

  Disclosed herein are methods of increasing retinal responsiveness to light in a subject, such as a subject with retinal degeneration. The disclosed methods include administering one or more compounds that decrease or inhibit γ-aminobutyric acid (GABA) signaling to a subject with retinal degeneration. In some embodiments, the methods include selecting a subject with retinal degeneration and administering a γ-aminobutyric acid C (GABA C ) receptor antagonist to the subject. In one example, the GABA C receptor antagonist is (1,2,5,6-tetrahydropyridin-4-yl)methylphosphinic acid (TPMPA). In other embodiments, the methods include selecting a subject with retinal degeneration and administering a metabotropic glutamate receptor (mGluR) antagonist to the subject. In one example, the mGluR antagonist is a mGlu1 receptor antagonist (for example, JNJ16259685).
