, (2009/06/27)
Provided herein are compounds of the formula (I): as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful for the treatment of diseases such as, for example, obesity.

Ambenonium (1), an old AChE inhibitor, is endowed with an outstanding affinity and a peculiar mechanism of action that, taken together, make it a very promising pharmacological tool for the treatment of Alzheimer's disease (AD). Unfortunately, the bisquaternary structure of 1 prevents its passage through the blood brain barrier. In a search of centrally active ambenonium derivatives, we planned to synthesize tertiary amines of 1, such as 2 and 3. In addition, to add new insights into the binding mechanism of the inhibitor, we designed constrained analogues of ambenonium by incorporating the diamine functions into cyclic moieties (4-12). The biological evaluation of the new compounds has been assessed in vitro against human AChE and BChE. All tertiary amine derivatives resulted more than 1000-fold less potent than 1 and, unlike prototype, did not show any selectivity between the two enzymes. This result, because of recent findings concerning the role of BChE in AD, makes our compounds, endowed with a well-balanced profile of AChE/BChE inhibition, valuable candidates for further development. To better clarify the interactions that account for the high affinity of 1, docking simulations and molecular dynamics studies on the AChE-1 complex were also carried out.

As part of a research program to develop compounds with mixed dopamine D4 and serotonin 5-HT2A antagonist activity with potential for the treatment of schizophrenia, we report a family of compounds based on structural modification of the atypical antipsychotic, clozapine (2). The chemical synthesis, structural characterization and pharmacological evaluation of a series 4′-arylmethyl analogues of clozapine are described. Preliminary receptor binding data are presented, examining primarily the electronic and positional effects of substituents on the introduced arylmethyl group, and secondarily the nature of the aryl ring.
