Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medicine, and particularly relates to a tricyclic compound, a preparation method thereof, and uses thereof. Background Art
[0002] The phosphodiesterase (PDE) enzyme superfamily contains 11 gene families, specifically PDE1 - PDE11. PDE3 and PDE4 are the main cAMP - hydrolyzing enzymes in smooth muscle tissue and are highly expressed in the airway smooth muscle of the lungs. PDE3 can hydrolyze both cAMP and cGMP, and its ability to hydrolyze cAMP is about ten times that of cGMP. PDE3 is the main PDE in airway smooth muscle cells. Inhibiting PDE3 blocks the metabolism of intracellular cAMP, and the accumulation of cAMP can cause a large amount of Ca 2+ to be released, thereby enhancing the contractility of smooth muscle, dilating the surrounding blood vessels, and relaxing bronchial smooth muscle. PDE4 can specifically hydrolyze cAMP and plays a major regulatory role in the expression of pro - inflammatory and anti - inflammatory mediators. PDE4 inhibitors can inhibit the release of harmful mediators by inflammatory cells. Therefore, inhibiting the hydrolysis of cAMP and cGMP by PDE3 / 4 can increase the intracellular concentration of cAMP and cGMP in the smooth muscle tissue of the lungs, thereby activating the downstream phosphorylation cascade, relaxing airway smooth muscle, and inhibiting inflammation. Given the important role of PDE4 in inhibiting airway inflammation, and the potential synergistic effect on airway caliber by enhancing bronchodilation through PDE3 inhibition and regulating inflammation and mucus production through PDE4 inhibition. Therefore, the combined inhibition of PDE3 and PDE4 has additive and synergistic anti - inflammatory and bronchodilation effects.
[0003] WO0058308A1 discloses a PDE3 / 4 dual - target inhibitor RPL554, which has positive clinical results and has been approved for marketing.
[0004]
[0005] However, its enzyme activity data shows that the inhibitory activity against PDE4 needs to be improved, and there is still room for improvement in the inhibitory activity against PDE3. Summary of the Invention
