Abstract

The invention belongs to the technical field of biological medicines, and particularly relates to an imidazole peptide deformylase inhibitor with an anti-tumor effect. In order to research and develop a novel small molecule compound targeting HsPDF, the invention discloses an imidazole peptide deformylase inhibitor with an anti-tumor effect, and the imidazole peptide deformylase inhibitor is novel in structure, better in activity and small in toxicity, has better anti-tumor activity, and can be used for preparing an anti-tumor drug. The compound has good inhibitory activity on various tumor cells (such as colorectal cancer cells, breast cancer cells and lung cancer cells), can be applied to preparation of anti-tumor drugs or drugs for inhibiting tumor cell proliferation, and has good application prospects in the anti-tumor aspect.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to an imidazole peptide deformylase inhibitor with antitumor effect. Background technique [0002] Malignant tumors have always been one of the major diseases that seriously threaten human life and health in the current society. Although with the rapid development of medical science and technology, new therapeutic drugs and treatment methods are constantly emerging, but due to changes in living environment and life pressure, the probability of cancer in the whole society is getting higher and higher, and it is getting younger and younger. Society and family come with a serious burden. According to the 2020 World Statistical Report, about 19.29 million people worldwide suffer from tumors, and there are 9.96 million deaths from cancer worldwide. The incidence and mortality of cancer are still increasing. At present, the main clinical methods for the treatment of mali...
