Description

Spiro-containing derivative with beta 2 receptor agonistic activity and M receptor antagonistic activity and application thereof in medicine
Technical Field
The invention relates to a nitrogenous heterocyclic spiro derivative, a preparation method thereof and application thereof in medicine, in particular to a derivative with muscarinic receptor antagonism and β2-dual active azaspiro derivatives of adrenergic receptor agonism or stereoisomers, hydrates, solvates, metabolites, pharmaceutically acceptable salts, co-crystals or prodrugs thereof, pharmaceutical compositions thereof and their use in medicine.
Background
Bronchodilators, which are widely used in clinics, include muscarinic receptor antagonists and β2Currently used inhaled muscarinic receptor antagonists include ipratropium bromide, oxitropium bromide, glycopyrrolate, tiotropium bromide, aclidinium bromide and umeclidinium bromide β2Adrenergic receptor agonists reverse bronchoconstrictor responses to various mediators, such as acetylcholine, by stimulating adrenergic receptors of airway smooth muscle β is currently used2Adrenergic receptor agonists include salbutamol, salmeterol, arformoterol, formoterol, vilanterol and indacaterol. These drugs, in addition to improving lung function, may also improve the quality of life and reduce the exacerbation of the disease.
As more clinical findings have been made, the combination of muscarinic receptor antagonist and β was demonstrated2Adrenergic receptor agonists are more effective than either therapeutic agent alone, and muscarinic receptor antagonists are now clinically used with β2-adrenoceptor agonists to prepare compound preparations for treatment of asthmaFor treating asthma and severe COPD, the compound preparation mainly comprises Anoro Ellipta (umeclidinium bromide/vilanterol), Ultbro Breezhaler (glycopyrronium bromide/indacaterol), ipratropium bromide/salbutamol, etc. Although the compound preparation has better treatment effect than the single preparation, the preparation of the preparation has higher requirements.
Therefore, it is desired to develop a compound having both muscarinic receptor antagonism and β2These compounds are administered as a single therapeutic agent, providing bronchodilatory action from two distinct and possibly synergistic modes of action2Adrenergic agonist dual action (MABA) compounds may also be combined with corticosteroid (ICS) anti-inflammatory agents drugs to form two therapeutic agents (MABA/ICS) to provide triple action therapeutic effects (Expert opin investig. drugs (2014)23(4): 453-.
Therefore, there is a need to develop novel compounds with both muscarinic receptor antagonism and β2Dual active agents of adrenergic stimulation to provide more effective single therapeutic doses or compound formulations, providing more clinical medication options for the patient.
