Expeditious Synthesis, Enantiomeric Resolution, and Enantiomer Functional Characterization of (4-(4-Bromophenyl)-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline-8-sulfonamide (4BP-TQS): An Allosteric Agonist-Positive Allosteric Modulator of α7 Nicotinic Acetylcholine Receptors
摘要:
An expeditious microwave-assisted synthesis of 4BP-TQS, its enantiomeric separation, and their functional evaluation is reported. Electrophysiological characterization in Xenopus oocytes revealed that activity exclusively resided in the (+)-enantiomer 1b (GAT107) and (-)-enantiomer 1a did not affect its activity when coapplied. X-ray crystallography studies revealed the absolute stereochemistry of 1b to be 3aR,4S,9bS. 1b represents the most potent ago-PAM of alpha 7 nAChRs available to date and is considered for further in vivo evaluation.

Compounds are provided which bind to an allosteric site on the mammalian alpha-7 nicotinic acetylcholine receptor (alpha-7 nAChR) and act as positive allosteric modulators with or without allosteric agonist activity. The compounds are useful in diagnosing, preventing, or treating a variety of disorders involving cognition, learning, memory, neurodegeneration, drug addiction, inflammation, chronic pain, and neuropathic pain. The compounds also can be used to enhance memory and learning in normal individuals.
