Embodiment 1

[0072] Example 1 Preparation of carbazole sulfonamide derivative co-crystal by evaporation of solvent

[0073] Add 0.1 mmol of the active pharmaceutical ingredient Compound 1 and 0.1 mmol of the guest molecule glutaric acid into 10 mL of the solvent tetrahydrofuran. After mixing and stirring for 15 minutes, let it stand for 30 minutes, filter, put the filtrate into a 25mL test tube, seal it with plastic wrap, pierce the hole, and place it at 25°C for natural volatilization. After 1 week, a solid-liquid mixture containing massive crystals was obtained. The resulting solid-liquid mixture was filtered to collect massive crystals, and dried at 60°C for 12 hours, and the obtained crystals were designated as sample 1-1 # .

[0074] Sample 1-2 # ~ Sample 1-21 # The preparation operation and sample 1-1 # The same, the difference is the type of raw material, dosage and volatilization temperature, sample 1-1 # ~ Sample 1-21 # See Table 1 for each substance type, consumption and so...

Embodiment 2

[0078] Example 2 Preparation of Carbazole Sulfonamide Derivative Cocrystal by Mixed Grinding Method

[0079] Add 0.1 mmol active pharmaceutical ingredient compound 1, 0.1 mmol guest molecule glutaric acid, and 0.1 mL ethanol into the mixing ball mill. Ball mill at room temperature for 30 minutes, and then dry at 60°C for 12 hours. The obtained solid sample is designated as sample 2-1 # .

[0080] Sample 2-2 # ~ Sample 2-13 # The preparation operation and sample 2-1 # The same, but the difference is the type of raw material, dosage and ball milling temperature. Sample 2-1 # ~ Sample 2-13 # See Table 2 for the types, amounts and milling temperatures of each material.

[0081] Add 0.1 mmol of compound 10 and 0.1 mmol of glutaric acid into the mixing ball mill. Ball milled at room temperature for 30 minutes, and the obtained solid sample was recorded as sample 2-14 # .

[0082] Sample 2-15 # ~Sample 2-25 # The preparative operation with samples 2-14 # The same, but t...

Embodiment 3

[0086] Example 3 13 C-NMR crystal characterization

[0087] Take oxalic acid crystals, sodium oxalate crystals, malonic acid crystals, sodium malonate crystals, glutaric acid crystals, sodium glutarate crystals, maleic acid crystals, and sodium maleate crystals respectively. 13 C-NMR analysis of -COOH of organic acids and -COO of organic acid salts - The chemical shift, as a benchmark, the results are shown in Table 3.

Abstract

The present application discloses a novel carbazole sulfonamide derivative eutectic and a preparation method thereof. The carbazole sulfonamide derivative eutectic is formed by oxalic acid, maleic acid, malonic acid or glutaric acid, and a carbazole sulfonamide derivative, has an antimicrotubular effect, and significant tumor resistance, and has the advantages of simple synthesis, small side effects, and high dissolution rate and solubility.

Description

technical field [0001] The application relates to a co-crystal of carbazole sulfonamide derivatives, which belongs to the field of chemistry. Background technique [0002] Tubulin inhibitors are a class of effective anti-tumor drugs. With the wide application of paclitaxel in clinical practice and the in-depth understanding of the structure and function of microtubules, the research on anti-tumor drugs targeting tubulin and development are increasingly attracting the attention of pharmaceutical companies worldwide. [0003] At present, paclitaxel and vinblastine tubulin inhibitors have been successfully used in the clinical treatment of various tumors, but as a natural product of macromolecules, their synthesis is difficult, their bioavailability is low, and they have toxic side effects. In particular, multiple The emergence of drug-resistant glycoproteins has seriously challenged its therapeutic properties. Therefore, it is necessary to synthesize new small-molecule tubul...
