A series of 2‐pyridylhydrazones derivedfrom phenyl‐pyridazin‐3‐yl‐methanones were prepared in search for potential novel antitumor agents. The stereochemistry of these compounds was established by means of NMR spectroscopy. Whereas hydrazones derivedfrom 3‐benzoylpyridazines (IC50 = 0.99–8.74 µM) inhibited the proliferation of the tumor cell lines tested, the non‐fully aromatic 3‐benzoylpyridazinone

, X, and n are as defined herein and the dotted line denotes an optional bond and pharmaceutically acceptable acid addition salts thereof. The compounds are useful in the treatment of neurological and neuropsychiatric disorders.
The synthesis and biological evaluation of a novel family of M-3 muscarinic antagonists are described. A systematic modification of the substituents to a novel alkyne-quinuclidine scaffold yielded original compounds displaying potent in vitro anticholinergic properties. (c) 2005 Elsevier Ltd.
