Tm. Bohme et al., Design and pharmacology of quinuclidine derivatives as M-2-selective muscarinic receptor ligands, BIOORG MED, 11(9), 2001, pp. 1241-1243
In our search for M-2-selective muscarinic receptor antagonists, we synthes
ized 1,3-disubstituted indenes. The effects of different basic moieties wit
h regard to binding and selectivity towards the five distinct muscarinic re
ceptor subtypes were investigated. The results show that the quinuclidine s
eries afforded the most promising compounds in terms of both receptor affin
ity and M-2-subtype selectivity. (C) 2001 Elsevier Science Ltd. All rights
