Embodiment Construction

[0117] Synthesis of the first part of the compound

[0118] The preparation of the compound of the present invention can be carried out according to the following process:

[0119] One, the preparation of compound (I)

[0120]

[0121] 1. Preparation of compound (I-3):

[0122] Dissolve compound (I-1), HOBt in anhydrous DCM and stir at -5°C for 10 min, then add EDIHCl at this temperature, stir for 15-20 min, then add compound (I-2) and stir for 15-20 min, then add DIPEA was stirred for 20 minutes, then moved to room temperature for reaction. After the reaction was complete, it was poured into water, extracted with DCM, and the combined organic phases were washed with dilute HCl, sodium bicarbonate solution, and saturated brine, dried over anhydrous sodium sulfate, and evaporated to dryness to obtain compound (I-3).

[0123] 2. Preparation of compound (I-4):

[0124] Compound (I-3) was dissolved in anhydrous DCM, TFA was slowly added dropwise at -5°C, stirred for 0.5 hou...

Description

technical field [0001] The invention belongs to the field of drug synthesis, and in particular relates to a novel tetrapeptide propylene oxide derivative and its application in pharmacodynamics. Background technique [0002] At present, malignant tumors are still one of the major diseases that threaten people's lives. Although the treatment of cancer has made great progress, it has not been able to treat cancer fundamentally. Although the currently marketed anticancer drugs have certain curative effects, most of them are cytotoxic drugs with serious toxic and side effects. Therefore, how to start from effective tumor targets to study targeted new anticancer drugs has become a top priority for medical workers. [0003] The Ubiquitin-Proteasome Pathway (UPP) can regulate the level of proteins involved in cell cycle control. This pathway has an important relationship with the pathogenesis of cancer, cardiovascular and cerebrovascular diseases and degenerative diseases of the ...
