[0017] Example 1: Compound DJBB-1 preparation of

[0018] The synthetic route is as follows:

[0019]

[0020] For the synthetic route of intermediate 1, please refer to the reference (Liu Wenhu et al., Acta Pharmaceutica Sinica, 2014, 49(2):217-224).

[0021] For the synthetic route of intermediate 2, please refer to the reference (Shoujiao Pengetal, J. Med. Chem. 2015, 58, 5242? 5255).

[0022] The synthetic route of compound DJBB-1 can be found in the reference (ShoujiaoPengetal, J.Med.Chem.2015, 58, 5242? 5255):

[0023] Add raw material 110mmol, intermediate 210mmol, CH 2 Cl 2 10ml, 10ml of triethylamine, stirred at room temperature for 10h. Then add saturated NH 4 Washed with Cl solution, CH 2 Cl 2 Extraction, washing with saturated brine, MgSO 4 Dried and concentrated. The crude product was separated by column chromatography with a yield of 65%.

Abstract

The invention provides application of a nitrogen mustard based piperlongumine compound in medicine. On the basis of the research on the nitrogen mustard based piperlongumine compound for inhibiting the activity of malignant cells, it proves that the nitrogen mustard based piperlongumine compound has the good anti-tumor activity, and a new choice is provided for preparing anti-tumor medicine.

Description

technical field [0001] The present invention relates to the use of nitrogen mustard amide compounds in medicine, in particular to the application of nitrogen mustard amide compounds in the treatment of malignant tumors. Background technique [0002] Piper longum is a perennial herbaceous vine. Traditional Chinese medicine takes its fruit ears as medicine. It is mainly used for cold pain in the abdomen, vomiting, diarrhea, migraine, nasal sinusitis, external treatment of toothache, coronary heart disease, and angina pectoris. Piperlongumine [0003] It is one of the main active ingredients isolated from Piper longum, and belongs to alkaloid compounds. With the deepening of its research, many pharmacological effects of perylene amide have been discovered. It has many pharmacological activities such as anti-platelet aggregation, analgesia, anti-fungal, anti-schistosome, anti-anxiety and anti-depression. In particular, it exhibits significant cytotoxicity to a variety of tumo...
