Embodiment Construction

[0118] The technical solutions of the present invention will be further described below through specific embodiments.

[0119] Synthesis of the first part of the compound

[0120] The preparation of the compound of the present invention can be carried out according to the following process:

[0121] One, the preparation of compound (II)

[0122]

[0123] 1. Preparation of compound (II-3):

[0124] Dissolve compound (II-1), HOBt in anhydrous DCM and stir at -5°C for 10 min, then add EDI·HCl at this temperature, stir for 15-20 min, then add compound (II-2) and stir for 15-20 min, Then DIPEA was added and stirred for 20 minutes, then moved to room temperature for reaction. After the reaction is complete, pour into water, extract with DCM, combine the organic phases with dilute HCl, NaHCO 3 The solution was washed with saturated brine, dried over anhydrous sodium sulfate, and evaporated to dryness to obtain compound (II-3).

Abstract

The invention discloses a tripeptide propylene oxide derivative or a pharmaceutically acceptable salt thereof and its preparation method and application. The structure of the tripeptide ethylene oxide derivative is shown in formula I. Compared with the prior art, The present invention provides a tripeptide epoxy ketone compound with a novel structure and the function of inhibiting proteasome. As a 20S proteasome inhibitor, they can block tumor cell proliferation and induce tumor cell apoptosis, so they can be used in humans and animals The treatment and prevention of a variety of diseases such as malignant tumors, the effect is significantly better.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to a novel tripeptide propylene oxide derivative, a preparation method thereof and an application in pharmacy. 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 degen...
