Problems solved by technology

[0002] Sulfonamides have a variety of biological activities and have always been a research hotspot in the field of medicinal chemistry. They are widely used in antibacterial, hypotensive, diuretic, etc. However, these drugs are bacteriostatic agents without bactericidal effect, and are prone to drug resistance Sexuality and frequent use will produce many adverse reactions, so its application range is greatly limited
However, due to its tendency to produce drug resistance, the scope of use has been gradually reduced

Abstract

The invention relates to synthesis of dihydropyrazol sulfonamide derivatives containing benzodioxane skeletons. The synthesis is characterized by being provided with a general formula shown in descriptions. The dihydropyrazol sulfonamide derivatives containing the benzodioxane skeletons play an obvious role in inhibiting human mammary cancer cells (MCF-7), cervical carcinoma cells (HeLa), lung cancer cells (A549), liver cancer cells (HepG2) and matrix metalloproteinase-2 (MMP-2), and meanwhile, show cell toxicity, which is equivalent to or better than that of positive control drugs, to human kidney epithelial cells (293T). Thus, the dihydropyrazol sulfonamide derivatives containing the benzodioxane skeletons can be applied to the preparation of anti-tumor drugs. The invention discloses a preparation method and anti-tumor bioactivity of the dihydropyrazol sulfonamide derivatives containing the benzodioxane skeletons.

Description

Contents of the invention [0001] The object of the present invention is to provide a class of synthesis of dihydropyrazolesulfonamide derivatives containing benzodioxane skeleton and its application in anticancer drugs Background technique [0002] Sulfonamides have a variety of biological activities and have always been a research hotspot in the field of medicinal chemistry. They are widely used in antibacterial, hypotensive, diuretic, etc. However, these drugs are bacteriostatic agents without bactericidal effect, and are prone to drug resistance Sexuality and frequent use will produce many adverse reactions, so that its application range is greatly limited. However, due to its easy drug resistance, the scope of use has been gradually reduced. However, the literature in recent years has repeatedly reported that its derivatives have activities other than antibacterial, the most notable of which is antitumor activity. [0003] Pyrazoles are an important class of heterocycl...
