Abstract

The invention provides a RBP2 enzyme activity inhibition small molecular compound WXSA-072A designed and synthesized for enzyme active sites, and provides a preparation method thereof. The experimentproves that the compound can significantly increase an H3K4me3 protein level in gastric cancer cells BGC-823 of a human, has an obvious function of inhibiting the RBP2 enzyme activity, and can reducea metastasizing ability of the gastric cancer cells BGC-823 of the human. According to the invention, the RBP2 enzyme inhibitor small molecular compound can be used for preparing anti-gastric cancer drugs as a gastric cancer inhibitor. The formula is shown in the specification.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and specifically relates to an RBP2 enzyme inhibitor small molecule compound WXSA-072A, a preparation method thereof and an anti-gastric cancer application. Background technique [0002] Antineoplastic drugs commonly used in clinical practice are mainly cytotoxic drugs, most of which have unavoidable disadvantages such as poor selectivity, strong toxic and side effects, and easy drug resistance. In recent years, with the rapid development of life science research, various basic processes such as signal transduction in malignant tumor cells, regulation of cell cycle, induction of apoptosis, angiogenesis, and interaction between cells and extracellular matrix are being investigated. The gradual clarification has brought about a huge change in the research and development concept of anticancer drugs. Therefore, using some key enzymes / proteins related to tumor cell modification as drug targets, ...
