  Synthesis and Pharmacological Profiling of Analogues of Benzyl Quinolone Carboxylic Acid (BQCA) as Allosteric Modulators of the M₁ Muscarinic Receptor

  摘要：

  Established therapy in Alzheimer's disease involves potentiation of the endogenous orthosteric ligand, acetylcholine, at the M, muscarinic receptors found in higher concentrations in the cortex and hippocampus. Adverse effects, due to indiscriminate activation of other muscarinic receptor subtypes, are common. M, muscarinic positive allosteric modulators/allosteric agonists such as BQCA offer an attractive solution, being exquisitely M-1-selective over other muscarinic subtypes. A common difficulty with allosteric ligands is interpreting SAR, based on composite potency values derived in the presence of fixed concentration of agonist. In reality these values encompass multiple pharmacological parameters, each potentially and differentially sensitive to structural modification of the ligand. We report novel BQCA analogues which appear to augment ligand affinity for the receptor (pK(B)), intrinsic efficacy (tau(B)), and both binding (alpha) and functional (beta) cooperativity with acetylcholine. Ultimately, development of such enriched SAR surrounding allosteric modulators will provide insight into their mode of action.

  An NMR Study of Halogenated 1,4-Dihydro-1-ethyl-4-oxoquinoline-3-carboxylates

  摘要：

  Ethyl 1,4-dihydro-1-ethyl-4-oxoquinoline-3-carboxylate and 29 of its mono-, di- and tri-fluoro and/or -chloro derivatives were synthesized and their H-1, C-13 and F-19 NMR spectra were recorded. H-1,C-13 and F-19 chemical shifts, J(HH), J(FH), J(CF) and J(FF) coupling constants are reported. The C-13 substituent chemical shift values of the chloro and fluoro substituents were calculated by linear multiple regression.
