  N-alkyl-nor-tropine esters of 2-phenyl-cyclohexenic acids as new bronchodilator agents. Effect of structural and conformational modifications on affinity for muscarinic receptors

  摘要：

  A series of N-alkyl-nor-tropine esters of 2-phenyl-2-cyclohexene-1-carboxylic, 2-phenyl-cyclohexanecarboxylic, and 2-phenyl-1-cyclohexene-1-acetic acids and their quaternary ammonium salts were synthesized and evaluated for bronchodilator activity by binding assays and pharmacological tests. The in vitro and in vivo functional activity results showed that some quaternary derivatives are potent anticholinergic bronchodilator agents, and 4 compounds (14-A, 16-A, 25-A and 28-A) were selected for pharmacotoxicological evaluation. The binding data also indicated that the affinity of these compounds for the tracheal membrane muscarinic receptors is markedly affected by structural modifications of both the cationic head and the acyl moiety of the molecule. In the series of N-alkyl-nor-tropine 2-phenyl-2-cyclohexene-1-carboxylate derivatives, a rather strict limitation of the bulk of the equatorial substituent of tropine nitrogen is required for very high affinity. Conformational analysis and molecular graphics techniques evidenced an influence of the acyl moiety conformation on the affinity of the different tropinic esters, suggesting that the carbonyl oxygen may participate in interaction with the binding site, eliciting a marked increase of potency when it is oriented in a proper conformation with respect to the tropinic nitrogen and the phenyl ring.

  摘要：

  Purpose. To design and evaluate a new class of soft anticholinergics with subtype selectivity.Methods. A new class of soft anticholinergics was designed based on the "inactive metabolite" approach. Four compounds were synthesized. The potency and soft nature of the compounds were evaluated by receptor binding, cardiac, and mydriatic studies. Stability and pharmacokinetic studies were also performed on these newly synthesized soft anticholinergics.Results. Receptor binding studies of the soft anticholinergics on cloned muscarinic receptors indicated pKi values in the range of 7.5 to 8.9. Two compounds, 9a and 13a, of the series showed muscarinic subtype receptor selectivity (M-3/M-2). In mydriatic studies, 13a and 13b showed shorter duration of action in the treated eyes than tropicamide. In the control eyes, significant dilation of pupils was found only in rabbits treated with atropine and tropicamide, indicating that the soft anticholinergics lack systemic effects because of their facile hydrolytic deactivation. Consistent with their soft nature, this new class of soft anticholinergics displayed much shorter cardiovascular effects in the carbachol-induced bradycardia (10 to 15 min) in rats than atropine (>60 min). Stability and pharmacokinetic studies suggested that the new soft anticholinergics were rapidly eliminated from plasma (systemic circulation) after i.v. administration.Conclusions. A new class of anticholinergics was designed and synthesized, and the PK/PD evaluation confirmed they were potent "soft" anticholinergics; two of them showed muscarinic receptor subtype selectivity (M-3/M-2).
