Abstract
Description
Compositions containing glucosamine derivatives, their preparation methods and uses
[0001] Cross-references to related applications
[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202410931495.3, filed on July 11, 2024, entitled “Compositions Containing Glucosamine Derivatives and Their Preparation Methods and Uses Thereof”, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to compositions containing glucosamine derivatives, methods for their preparation and uses, and particularly to compositions containing 2-N-4,6-di-O-tributyryl-D-glucosamine, methods for their preparation and uses. Background Technology
[0004] Glucosamine, also known as glucosamine, is a compound formed by replacing one of the hydroxyl groups of glucose with an amino group. Glucosamine is an important precursor in the glycosylation of proteins and lipids and is one of the most abundant monosaccharides in nature. Typical glucosamine compounds include N-acetylglucosamine (GlcNAc) and N-butyrylglucosamine (GlcNBu). GlcNAc is a monomer of chitin and is considered to have anti-inflammatory, antitumor, and antioxidant effects, with wide applications in food, medicine, and cosmetics. Some studies have also shown that GlcNBu has therapeutic potential in bone and joint diseases.
[0005] Prodrug-based glucosamine derivatives have been developed to enhance or improve their efficacy in treating bone and joint diseases (such as osteoporosis and arthritis) by increasing bioavailability, stability, and reducing compound metabolism. Examples include compounds of formula (A) disclosed in patent documents CN109929001A and WO2019119117A1. Among these, N-butyryl-4,6-di-O-butyryl-D-glucosamine shows therapeutic effects in alleviating pain symptoms, cartilage degeneration, chondrocyte aggregation, and osteophyte formation in meniscectomy-induced osteoarthritis (OA) in rats.
[0006] Currently, the vast majority of patent applications related to glucosamine derivatives involve GlcNAc, such as WO2022161485A1, JP2023061032A, KR1020230001077A, JP2022000001A, US11110051B2, etc. On the one hand, in these patent applications, GlcNAc is mixed with other active ingredients to form compositions, and the vast majority of these are health products or beauty products, rather than pharmaceutical compositions. On the other hand, GlcNAc and GlcNBu prodrugs differ significantly in physicochemical properties and other aspects. Existing patent literature on GlcNAc-containing compositions offers no reference for the development of GlcNBu prodrugs (such as compounds of formula (A), especially N-butyryl-4,6-di-O-butyryl-D-glucosamine) compositions (especially pharmaceutical compositions). Summary of the Invention
[0007] The technical problem to be solved by this disclosure is a composition containing a glucosamine derivative, a method for preparing the composition, and its uses. Specifically, the glucosamine derivative is a prodrug of GlcNBu or a pharmaceutically acceptable salt thereof. In the compositions of this disclosure, the prodrug of GlcNBu, as the main active ingredient, exhibits excellent dissolution properties and excellent absorption in vivo. Furthermore, these compositions possess good stability and remain stable under long-term storage conditions, and can be used for the prevention and / or treatment of bone and / or joint diseases, such as osteoporosis and / or arthritis.
[0008] This disclosure provides a composition containing a glucosamine derivative comprising 55 wt% to 70 wt% of a prodrug of GlcNBu as shown in Formula (I) or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable excipient.

The test results are shown in Table 4.
[0156] Table 4. Dissolution rate of compound 1 in Examples 1 to 6 and Comparative Examples 1 to 2
[0157] It can be seen that the tablets of Examples 1-6 all showed good dissolution of compound 1 after 30 minutes. However, the capsules of Comparative Examples 1 and 2 showed insufficient dissolution of compound 1 after 30 minutes.
[0158] Test Example 3: Pharmacokinetic Study
[0159] Samples from Examples 1 and 5 (500mg strength) were selected for pharmacokinetic studies in beagle dogs. Oral administration was used, with two male beagle dogs in each group. Blood samples were collected at regular intervals (5 min, 10 min, 20 min, 30 min, 1 h, 1.5 h, 2 h, 3 h, 4 h, and 6 h) after administration for substance analysis. A control group was established with Comparative Example 1. The results are shown in Table 5 below.
[0160] Table 5. Pharmacokinetic parameters of Examples 1 and 5 and Comparative Example 1
[0161] As can be seen from Table 5, compared with Comparative Example 1, both Example 1 and Example 5 have a longer half-life T. 1 / 2 Furthermore, the exposure levels (AUC) and Cmax of the sample in Example 1 were similar to those in Comparative Example 1, meeting the requirements for clinical drug use. Although the Cmax of Example 5 was slightly lower than that of Comparative Example 1, the exposure level was close to that of Comparative Example 1.
[0162] Test Example 4 Stability Test
[0163] Impurities in the tablets of Examples 1, 2, and 5 were analyzed using high-performance liquid chromatography (HPLC), and the results are shown in Table 6 below. Table 6 shows that compound 1 in the coated tablets prepared using the dry granulation process exhibits good stability, and its content remains essentially unchanged.

[0165] In addition, the stability of compound 1 in water was tested (HPLC method), and the results are shown in Table 7 below.
[0166] Table 7. Stability of Compound 1 in Water
[0167] It can be seen that when compound 1 is in water, the total impurities gradually increase over time, indicating its instability in water. When using a wet process, the impurity content in the composition increases significantly, posing a risk of degradation for compound 1. Furthermore, compound 1 has a melting point of approximately 87°C-94°C; if higher temperatures are used in the preparation process (e.g., high-temperature drying), compound 1 risks melting.
[0168] Test Example 5 Storage Stability
[0169] The storage stability of the tablets from Example 1 was investigated. They were stored at 40°C and 75% RH for 6 months, and at 25°C and 60% RH for 2 years. Impurities were analyzed using high-performance liquid chromatography (HPLC), and the results are shown in Table 8 below. The results indicate that the tablets from Example 1 exhibit good storage stability.
[0170] Table 8. Storage stability of Example 1
[0171] Based on the above test results, it can be seen that the composition containing glucosamine derivatives disclosed herein has excellent dissolution performance and good stability.
