Problems solved by technology

However, these 4-anilinequinazoline compounds only have an inhibitory effect on tumors and cannot effectively kill cancer cells. Only about 60% of patients with non-small cell lung cancer will have T790M drug resistance mutations , and the choice of follow-up drug treatment is very limited, and almost all other inhibitors of this type have similar drug resistance problems

Abstract

The invention discloses a zidovudine spliced 4-aniline quinazoline compound as well as a preparation method and application of the zidovudine spliced 4-aniline quinazoline compound. The compound simultaneously contains zidovudine and 4-aniline quinazoline skeleton structures, has potential biological activity, provides a compound source for biological activity screening, has important application value for drug screening and pharmaceutical industry, and has a good application prospect through in-vitro anti-tumor activity screening. It is found that the compounds have a remarkable inhibition effect on a human non-small cell lung cancer cell line (A549), a human breast cancer cell line (MCF-7), a human cervical cancer cell line (Hela), a human liver cancer cell line (HepG2) and a human lung adenocarcinoma cis-platinum-resistant strain (A549 / DDP), and the anti-tumor effect strength of part of the compounds is 10 times or above that of positive control erlotinib. The inhibition of EGFR enzyme activity shows that the compound can synergistically play an anti-tumor role from a plurality of signal channels, and has the potential to be developed into a new anti-tumor drug.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a zidovudine-spliced ​​4-aniline quinazoline compound and its application in antitumor-related drugs. Background technique [0002] Zidovudine, also known as azidethymidine, is usually used alone or in combination with other drugs to treat human immunodeficiency virus (HIV) infection. Studies in recent years have shown that zidovudine can exert anti-tumor and radiosensitizing effects by inhibiting telomerase activity, and its anti-tumor related research has involved breast cancer, cervical cancer, ovarian cancer, vaginal cancer, T lymphoma, primary Kitt lymphoma, glioma, liver cancer, gastric cancer, bladder cancer, parathyroid cancer, colon cancer, lung cancer, prostate cancer, Kaposi's sarcoma, head and neck cancer, laryngeal squamous cell carcinoma, oral cancer, leukemia and other tumors Treatment, and the curative effect research on malignant tumors such as parathyroid can...
