The invention relates to a quinuclidine derivative, a pharmaceutically acceptable salt, pro-drug and solvent compound of the quinuclidine derivative, a method for preparing the quinuclidine derivative, a drug composition with the quinuclidine derivative and the pharmaceutically acceptable salt, pro-drug and solvent compound and pharmaceutical application of the quinuclidine derivative. The quinuclidine derivative, the pharmaceutically acceptable salt, pro-drug and solvent compound, the method, the drug composition and the pharmaceutical application have the advantage that the compound is excellent in M3 receptor antagonist activity and accordingly can be used as a novel efficient drug for chronic obstructive pulmonary diseases.

Replacement of the central, para-substituted fluorophenyl ring in the γ-secretase inhibitor 1 (BMS-708,163) withthe bicyclo[1.1.1]pentane motif led to the discovery of compound 3, an equipotent enzyme inhibitor with significant improvements in passive permeability and aqueous solubility. The modified biopharmaceutical properties of 3 translated into excellent oral absorption characteristics (~4-fold Cmax and AUC values relative to 1) in a mouse model of γ-secretase inhibition. In addition, SAR studies into other fluorophenyl replacements indicate the intrinsic advantages of the bicyclo[1.1.1]pentane moiety over conventional phenyl ring replacements with respect to achieving an optimal balance of properties (e.g., γ-secretase inhibition, aqueous solubility/permeability, in vitro metabolic stability). Overall, this work enhances the scope of the [1.1.1]-bicycle beyond that of a mere spacer unit and presents a compelling case for its broader application as a phenyl group replacement in scenarios where the aromatic ring count impacts physicochemical parameters and overall drug-likeness.
