Vi. Cohen et al., SYNTHESIS OF SOME DIBENZODIAZEPIONE DERIVATIVES AS POTENT AND M2-SELECTIVE ANTIMUSCARINIC COMPOUNDS, Journal of heterocyclic chemistry, 31(4), 1994, pp. 787-791
Two series of -[[4-[4-(dialkylamino)butyl]-1-cyclohexyl]acetyl], and 1
0,11-dihydro-5H-dibenzo[b,e][1,4]diazepin-11-ones were synthesized as
potential m2-selective ligands 1,2. Their affinity and selectivity for
the muscarinic cholinergic receptor m-AChR subtypes were determined.
Replacing a nitrogen with CH in the piperidine ring of 0,11-dihydro-5H
-dibenzo-[b,e][1,4]diazepin-11-ones 3 significantly altered the affini
ty and selectivity to the muscarinic receptor subtypes.
