[0027] 1.1 Synthesis of N,N-bis(2-hydroxyethyl)-2-nitroaniline

[0028] Add 1.58g (10mmol) of o-nitrochlorobenzene and 2.12g (20mmol) of diethanolamine into a 25mL round-bottomed flask, and then heat it to 115-120°C to react. TCL detects the reaction process. After 7 hours, the reaction is basically complete, and the reaction is stopped. The entire reaction system was poured into 90°C hot water while it was hot and stirred vigorously. The product was precipitated in the form of oil, and then the oil was extracted with ethyl acetate, washed with water, dried, and purified by column chromatography (petroleum ether: ethyl acetate). Ester = 1:1) separation and purification to obtain a purple oily product with a yield of 39%. The obtained spectrum is consistent with that reported in the literature.

Abstract

A new crown ether ring-shaped quinazoline nitrogen mustard compound or a pharmaceutically-acceptable salt thereof is characterized in that: one end is provided with a nitrogen mustard alkylated group; the other end is provided with a 6,7-substituted crown ether ring-shaped quinazoline structure; a substituted group R is located at a site 4 of a quinazoline matrix and represents 2-nitrogen mustard group, 3-nitrogen mustard group or 4-nitrogen mustard group; a crown ether ring is located at sites 6 and 7 of the quinazoline matrix and represents 9-crown-3, 12-crown-4 or 15-crown-5; and the compound has a structure represented by a formula I. Experiments show that the compound has better antitumor activity and also has selectivity on different tumor cells. At the same time, the compound is easy to synthesize and simple in operation. Advantages of the compound show that the compound has great potential to become a drug for treatment of tumor.

Description

Technical field: [0001] The invention relates to a new class of crown ether cyclic quinazoline mustard compounds, a preparation method thereof and an application as a drug for treating tumors. Background technique: [0002] Tumor is a major killer threatening human health. However, its pathogenesis is complicated and difficult to treat. Scientists are trying to find better anti-tumor drugs to treat it through continuous efforts. [0003] Nitrogen mustard compounds are an early and important class of alkylated antineoplastic drugs. These drugs are easy to synthesize and low in cost. They are widely used clinically and play an important role in the treatment of tumors. However, due to the high toxicity, poor selectivity, and low therapeutic efficiency of this class of drugs, it has greatly attracted and encouraged countless researchers to devote themselves to the research and development of nitrogen mustards. The carrier part of the nitrogen mustard can be used to improve th...
