The present invention relates to substituted pyrrolidinone compounds of formula 1,
1
wherein n is 0 or 1; Aza is a heterocycle optionally substituted with C
1-4
alkyl, or C
1-4
alkyl substituted with a heterocycle, which represents a saturated or unsaturated five- or six-membered ring having nitrogen(s) as a heteroatom, which are muscarinic acetylcholine receptor agonists and useful as nootropics and therapeutic agents for cerebral neural diseases such as Alzheimer's disease; and pharmaceutically acceptable salts thereof; processes for the preparation thereof; and pharmaceutical compositions comprising these compounds or salts.

isoxazoline core of the lead compound 1 previously reported resulted in the loss of its agonistic activity. One exception was the compound 6f having oxadiazole core and 2‐azabicyclo[2.2.1]heptane substituent. Of the twoisomers of 6f, exo‐isomer (EC50 0.013 μM) was five‐ to six‐fold more effective than endo‐isomer (EC50 0.30 μM), and ca. two‐fold active than the mother compound 1 (EC50 0.031 μM) in stimulating
