[0153] Compound preparation

[0154]The compounds represented by general formula V and general formula X of the present invention can be prepared according to the following scheme and referring to synthetic methods known in the art. In general, in the preparation schemes described below, each reaction is carried out at -10°C to reflux temperature, usually at room temperature (about 25°C) to reflux temperature. Preferably, the reaction temperature is 5-100°C, more preferably 20-80°C. The reaction time is usually not particularly limited, and generally ranges from 1 minute to 24 hours, preferably from 1 to 20 hours. Wherein, the solvent used is usually a polar solvent, such as water, DMF, alcohol (such as methanol, ethanol, isopropanol, etc.). Synthesized compounds can be used physical and chemical methods, such as hydrogen spectrum ( 1 H-NMR), mass spectrometry (MS) and elemental analysis for structural identification.

Abstract

The invention discloses a sulfonamide compound, a pharmaceutical composition, a preparation method and an application thereof. The sulfonamide compound of the present invention can be used as a small-molecule tubulin inhibitor, which not only has an anti-microtubule effect in vitro, but also can induce tumor cell apoptosis, and has an obvious inhibitory effect on multi-drug resistant cells. oral antitumor activity in vivo. In addition, this type of compound has the advantages of small molecular weight, simple synthesis, and less toxic and side effects. The invention also provides a pharmaceutical composition containing the sulfonamide compound and its pharmaceutically acceptable salt as an active ingredient.

Description

technical field [0001] The invention belongs to the field of medicines, and in particular relates to a new sulfonamide compound, a pharmaceutical composition, a preparation method and an application thereof. Background technique [0002] Tumor is a kind of disease characterized by uncontrolled cell growth and proliferation. Abnormalities in cell proliferation, differentiation and apoptosis are all involved in the occurrence and development of tumors. Chemotherapy is one of the main treatment methods for malignant tumors. According to the different sensitivity of chemotherapy drugs to tumor cells at different stages, chemotherapy drugs can be divided into two categories: the first category is cell cycle non-specific drugs (CCNSA): these drugs It can kill tumor cells in all phases of the cell cycle, including G0 phase (quiescent cell population) cells. Such drugs include alkylating agents, anticancer antibiotics, and hormones. The second category is cell cycle-specific drugs...
