preparation example Construction

[0058] The preparation method of the indene-1-ylidene sulfonyl benzoyl hydrazide derivative shown in above-mentioned formula I, its synthetic steps are:

[0059] 1) at In THF (tetrahydrofuran), m-chlorosulfonylbenzoic acid was added dropwise at 0°C, and then reacted at room temperature for 8-12h to obtain intermediate 2;

[0060] 2) dissolving the carboxylic acid in methanol, adding a catalytic amount of concentrated sulfuric acid dropwise, and reacting with intermediate 2 to obtain intermediate 3;

[0061] 3) Dissolving intermediate 3 in methanol, adding 2 to 5 eq of hydrazine hydrate, and reacting at 65 to 70°C for 12 hours to obtain intermediate 4;

[0062] 4) Intermediate 4 is then combined with reaction to obtain the compound of formula I.

[0063] Wherein, in the preparation method of the above-mentioned indene-1-ylidenesulfonylbenzohydrazide derivatives, the m-chlorosulfonylbenzoic acid described in step 1) and The molar ratio is 1:3.

[0064] Wherein, in the ab...

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and specifically relates to indene-1-ylidenesulfonylbenzohydrazide derivatives and their preparation methods and applications. Background technique [0002] Malignant tumors are one of the most serious diseases that threaten human life and health, and have become the second leading cause of death in humans next to cardiovascular diseases. Moreover, the latest statistics show that worldwide, especially in developing countries, the incidence and mortality of malignant tumors have been increasing year by year. Chemotherapy is the most important treatment for malignant tumors besides surgery and radiotherapy. Traditional chemotherapeutic drugs mainly act on common components related to the life and death of all cells, such as DNA, RNA, and tubulin, resulting in low selectivity and high toxicity. Targeted therapy drugs, which act on key molecules and signal transduction pathways that regulate c...
