  Structure−Activity Relationships of Dimethindene Derivatives as New M₂-Selective Muscarinic Receptor Antagonists

  摘要：

  A series of 2,3-disubstituted indenes, which are analogues of the widely used histamine H, receptor antagonist dimethindene, have been synthesized and studied as muscarinic and histamine receptor antagonists. The affinities of these compounds for the five human muscarinic receptor subtypes (M-1-M-5) and for human histamine H, receptors were determined in radioligand binding studies using membranes from transfected Chinese hamster ovary (CHO) cells and [H-3]N-methylscopolamine ([H-3]NMS). The results demonstrate that the diisopropyl analogue 19 has a similar high affinity as (S)-dimethindene at M-2 receptors ((S)-dimethindene: pK(i) = 7.52; (-)-19: pK(i) = 7.37) with an improved selectivity pattern ((S)-dimethindene: M-2/M-1 = 6-fold, M-2/M-3 = 5-fold, M-2/M-4 = 10-fold, M-2/M-5 = 25-fold; (-)-19: M-2/M-1 = 36-fold, M-2/M-3 = 96-fold, M-2/M-4 = 42-fold, M-2/M-5 = 275-fold). In addition, compound (-)-19 showed 35-fold lower affinity at histamine H-1 receptors (pK(i) = 5.61) than (S)-dimethindene (pK(i) = 7.16). Another interesting compound is the fluoroethyl derivative 20 (pK(i)/M-2 = 7.49), which also exhibits a higher M-2 selectivity (M-2/M-1 = 19-fold; M-2/M-3 = 22-fold; M-2/M-4 = 13-fold; M-2/ M-5 = 62-fold) than (S)-dimethindene. Unfortunately, compound 20 also shows a high affinity for histamine H-1 receptors (pK(i) = 8.14). The compound with the highest affinity for M-2 receptors (pK(i) = 7.91), the dimethylaminomethylene analogue 31, displayed only a small preference for M-2 receptors. In conclusion, compound (-)-19 might be useful to test the hypothesis that blockade of muscarinic M-2 receptors in the brain is a viable mechanism by which to produce improved cognition. This second-generation dimethindene analogue might also be the starting point for the development Of M-2-selective muscarinic antagonists useful for quantifying M-2 receptors in the central nervous system with positron emission tomography imaging.

  A series of indene analogs of the H1-antihistamine (−)-R-dimethindene was evaluated for selectivity in the search for potentially improved sedative-hypnotics. Variation of the 6-substitutent in the indene core in combination with a pendant electron rich heterocycle led to the identification of several potent H1-antihistamines with desirable selectivity over CYP enzymes, the M1 muscarinic receptor and
