M3 muscarinic acetylcholine receptor antagonists: SAR and optimization of bi-aryl amines
摘要:
Exploration of multiple regions of a bi-aryl amine template led to the identification of highly potent M-3 muscarinic acetylcholine receptor antagonists such as 14 (pA(2) = 11.0) possessing good sub-type selectivity for M-3 over M-2. The structure-activity relationships (SAR) and optimization of the bi-aryl amine series are described. (C) 2009 Elsevier Ltd. All rights reserved.

beta-Lactams are used routinely to treat Staphylococcus aureus infections. However, the emergence of methicillin-resistant S. aureus (MRSA) renders them clinically precarious. We describe a class of cinnamonitrile adjuvants that restore the activity of oxacillin (a penicillin member of the beta-lactams) against MRSA. The lead adjuvants were tested against six important strains of MRSA, one vancomycin-intermediate S. aureus (VISA) strain, and one linezolid-resistant S. aureus strain. Five compounds out of 84 total compounds showed broad potentiation. At 8 mu M (E)-3-(5-(3,4-dichlorobenzy1)-2-(trifluoromethoxy)phenyl)-2-(methylsulfonyl)acrylonitrile (26) potentiated oxacillin with a >4000-fold reduction of its MIC (from 256 to 0.06 mg.L-1). This class of adjuvants holds promise for reversal of the resistance phenotype of MRSA.
