Abstract

The invention provides a novel compound containing a five-membered ring, which is characterized by being a compound shown in the following structure:

Description

Five-membered ring-containing compound and preparation and application thereof
Technical Field
The invention relates to the field of medical chemistry, in particular to a compound containing a five-membered ring, a preparation method thereof and application thereof in treating xerophthalmia.
Background
The permanent wetting and lubrication of the eye by tears is critical to maintaining vision and eye comfort. Tears are composed of water, oil, mucus, antibodies, and some specific proteins (used to fight infection). These components are secreted by specific glands located around the eye. When there is an imbalance in the tear system, a person feels dry.
Dry eye syndrome is a common ocular surface inflammatory disease. People with dry eye may experience eye pain, photosensitivity, itching, redness and blurred vision. Dry eye syndrome has a variety of causative factors including age, sex, environment, drugs, surgery, and systemic diseases such as autoimmune diseases, diabetes, thyroid diseases, lymphoma, etc. Failure to properly diagnose and treat dry eye may lead to further complications such as infection, ocular surface keratinization, corneal ulceration, and conjunctival squamous, among others.
Thus, dry eye is a very large disease that afflicts 5-10% of the population, especially those who have been working for long periods of time before computers, and beyond. More than 30% of ophthalmologists outpatient visits today are dry eye patients. China despite its numerous dry eye patients, to date no drugs have been approved for the treatment of dry eye. The patient can only have temporary relief from the artificial tears. Therefore, there is an urgent need for drugs for treating dry eye.
The incidence and age of dry eye is directly proportional, with about 20% of people over 50 years of age having varying degrees of dry eye; gender also affects dry eye, which is much higher in women, particularly in older women, than in men, and may be associated with the secretion of sex hormones; white-collar workers are in an air-conditioning environment for a long time, and the incidence rate of xerophthalmia of the crowd is also high due to the fact that the white-collar workers use the screen for a long time. Dry eye disease is a continuous pathological process, and the disease condition continuously develops from mild condition to severe condition, and no obvious boundary exists between mild condition, moderate condition and severe condition. Despite the complex etiology of dry eye, studies have found that the pathology of dry eye, which is triggered by a variety of causes, is similar: the immune cells infiltrate the surface tissues of the eye to cause chronic inflammation and damage to the ocular surface. Currently, there are two drugs approved in the european and american markets: and (1) a cyclosporine A suspension. The drug is a very powerful immune system suppressor and thus may cause damage to the immune system. Meanwhile, because the suspension liquid is a suspension liquid, the problems of long-term storage stability, irritation to eyes of patients in use and the like exist; (2) Lifitigrast, a drug approved by FDA in the united states for 12 months in 2016, is an inhibitor of migration of immune cells, and achieves therapeutic effects by preventing immune cells from entering sites of inflammation; however, the drug is highly lipophilic and has no clinical effect in >50% of patients.
