Abstract

A novel quinazoline nitrogen mustard compound, characterized in that: one end has a nitrogen mustard alkylating group; the other end has a 6,7-substituted quinazoline structure, and the substituent R1 is located at the 4-position of the quinazoline parent, 2-, 3-, 4- nitrogen mustard groups; substituents R2, R3 are respectively located on the 6 and 7 positions of the quinazoline parent, and are methoxyethoxy, methoxy, morpholine propoxy, 3-tetrahydrofuryloxy and hydroxyl. The structure is as formula A. Experiments show that this kind of compound can cause cross-linking of DNA and is a bifunctional alkylating agent. Anti-tumor activity experiments in vivo show that the compound has good activity. Not only that, this type of compound also has the advantage that nitrogen mustards do not have, namely less toxicity. Simultaneously, the compounds are easy to synthesize, and the total yield is high. All these advantages show that this kind of compound has great potential to be a tumor treatment drug.

Description

technical field [0001] The invention relates to a class of novel quinazoline mustard compounds, a preparation method thereof and an application as a drug for treating tumors. Background technique: [0002] Tumor is a disease that seriously threatens human health. Over the years, scientists from various countries have made unremitting efforts to find out more suitable tumor chemotherapy drugs for tumor treatment. [0003] Nitrogen mustards are the earliest anti-tumor alkylating agents used clinically. Since their inception, the development of new nitrogen mustards has been going on for a long time. In the development process of nitrogen mustard drugs, how to introduce new drug carriers to reduce drug toxicity and increase tumor selectivity, thereby improving the therapeutic index, is the common goal of scientists from all over the world. At present, research based on this idea is mainly focused on the following three directions: introducing sugars and their derivatives into...
