G. Cignarella et al., SYNTHESIS OF A NEW SERIES OF 2,7-DIAZASPIRO[3.5]NONAN-1-ONES AND STUDY OF THEIR CHOLINERGIC PROPERTIES, European journal of medicinal chemistry, 29(2), 1994, pp. 115-120
A new series of substituted 2,7-diazaspiro[3.5]nonan-1-ones (la-1), st
ructurally related to the muscarinic agonist RS-86, has been synthesiz
ed and tested for cholinergic properties both in vitro and in vivo. No
ne of the compounds showed significant cholinergic properties at eithe
r the central or peripheral level. A possible explanation for the lack
of activity is given.
