Abstract
Description
New use of N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine or its salt Technical Field
[0001] The present invention relates to use of N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine or a salt thereof in preparing a medicament for preventing or treating bronchiectasis. Background Art
[0002] N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine (referred to as Compound A in the present invention) has the following structure:
[0003] This compound is a neutrophil elastase inhibitor developed by a Japanese company and first launched on the market in 2002. In 2020, it was approved for marketing in China for the treatment of acute lung injury or acute respiratory distress syndrome.
[0004] Prior art has disclosed injections and inhalation formulations of this compound. For example, Document 1 discloses a lyophilized injection formulation of this compound, comprising N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine monosodium salt tetrahydrate and at least one pH adjuster selected from trisodium phosphate or its hydrate, sodium hydroxide, or potassium hydroxide. Document 2 discloses an inhalation formulation comprising N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine monosodium salt or its hydrate, a pH adjuster, and an osmotic pressure regulator. No literature directly reports that N-[2-[[[4-(2,2-dimethyl-1-oxopropoxy)phenyl]sulfonyl]amino]benzoyl]-(S)-glycine or its salt can be used to treat bronchiectasis.
[0005] Bronchiectasis, also known as bronchiectasis, refers to a heterogeneous group of diseases characterized by recurrent purulent bronchial inflammation following acute or chronic respiratory infections and bronchial obstruction, leading to structural destruction and thickening of the bronchial walls, resulting in abnormal and persistent bronchial dilation. Bronchiectasis can be primary or secondary. Clinical manifestations include persistent or recurrent cough, coughing up large amounts of purulent sputum, and / or recurrent hemoptysis, which can lead to respiratory dysfunction and cor pulmonale. Bronchiectasis is primarily categorized as cystic fibrosis (CF)-induced bronchiectasis and non-CF-induced bronchiectasis.
[0006] Some neutrophil elastase inhibitors have been clinically tested for the treatment of bronchiectasis, such as AZD 9668 (Reference 3) and BAY 85-8501 (Reference 4). The results of AZD 9668 in the treatment of patients with bronchiectasis showed improvements in some lung function (FEV1, SVC) and some inflammatory biomarkers in sputum (IL-8, IL-6), but no significant differences were observed in sputum neutrophil count, neutrophil elastase (NE) activity, sputum weight, or quality of life compared with the placebo group. In a study of BAY 85-8501 in the treatment of non-cystic fibrosis bronchiectasis, with the exception of a slight increase in sputum inflammatory factor IL-8 levels, no statistically significant differences were observed in other biomarkers, sputum weight, sputum NE content, NE activity, or lung function compared with the placebo group. Therefore, there is an urgent need to develop an effective therapeutic drug for bronchiectasis.

DETAILED DESCRIPTION
[0026] The present invention will be described in further detail below with reference to the examples, but the embodiments of the invention are not limited thereto. Unless otherwise specified, the experimental animals, reagents, detection methods, data statistical methods, etc. used in the specific examples of the present invention can be obtained by conventional methods in the art.
[0027] Example 1
[0028] Animal experiments
[0029] Male SD rats were divided into 5 groups, each with 10 rats, namely, a blank control group, a model group, and a group treated with 2.5 mg / mL, 7.5 mg / mL, and 25 mg / mL of inhaled Compound A monosodium salt. Except for the blank control group, the rats in the other groups were treated with a bronchiectasis rat model according to the method described in the literature (Shanghai Experimental Animal Science, 2000, 20(2): pp. 65-68). One hour after modeling, the rats in the inhaled Compound A monosodium salt groups were given inhalation of various concentrations of Compound A monosodium salt (nebulized using a compressed nebulizer and inhaled through the rats' mouths and noses) for 30 minutes. The rats in the blank control group and the model group were given 0.9% NaCl by nebulization for 30 minutes. Each group of animals was given the drug twice, with an interval of approximately 8 hours. The rats were killed 24 hours after modeling, the left lung was ligated, and the right lung bronchoalveolar lavage was performed. The total white blood cell count, eosinophils, lymphocytes and macrophages in the lavage fluid were counted; part of the bronchi and left lung were homogenized and the neutrophil elastase activity in the bronchial and lung tissues was measured.
[0030] Table 1. Inhalation dose delivered to rats by aerosol administration of Compound A monosodium salt
[0031] The neutrophil elastase (NE) activity of rats in each group is shown in the following table.
[0032] Table 2. Neutrophil elastase activity in rats of each group (Mean±SD)
[0033] Note: Compared with the blank control group: # P<0.05; compared with the model group: * P<0.05, ** P<0.01,***P<0.001.
[0034] Animal experiments show that the compound of the present invention has a good therapeutic effect on bronchiectasis model rats.
