Embodiment

[0068] Compounds of the formula A in which the substituents R1=hydrogen, R2=nitrogen mustard are prepared according to the following steps.

[0069] 1.1 Synthesis of N, N-bis(2-hydroxyethyl)-3-nitroaniline

[0070] Take 5.52 g (0.04 mol) of 3-nitroaniline, add it to 80 mL of 25% acetic acid aqueous solution, and add 10 mL of ethylene oxide dropwise under ice cooling. Warm up to room temperature, stir for 72 hours, filter with suction, wash the filter cake with water, and dry to obtain 8.02 g of a yellow-orange solid, with a yield of 88%. mp94-96℃, 1 H NMR (400MHz, CDCl 3 )δ7.53 (d, J=8.0Hz, 1H, ArH), 7.48 (s, 1H, ArH), 7.33 (t, J=8.2Hz, 1H, ArH), 6.97 (dd, J=8.4, 2.2Hz , 1H, ArH), 3.89 (t, J=4.8Hz, 4H, -NCH 2 CH2-), 3.65(t, J=4.8Hz, 4H, -CH 2 CH 2 OH). 13 C NMR (100MHz, CDCl 3 )δ149.43, 148.63, 129.84, 118.10, 111.34, 106.48, 60.35, 55.06.MS (ESI + ) m / z: 227.3 (M+H + ).IR(KBr pellet, cm -1 ): 3265, 3173, 2959, 2863, 1618, 1565, 1525, 1486, 1341, 1290, 1040.

Abstract

The novel nitrogen mustard derivative is 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, which is 2- or 3 - the nitrogen mustard group; the 6 and 7 positions of the quinazoline parent are morpholine propoxy and methoxy. The structure is as formula A. Experiments show that this kind of compound can inhibit cell cycle in G2 / M phase, and is a kind of 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. Various advantages show that this kind of compound has great potential to be a tumor treatment drug.

Description

Technical field: [0001] The invention relates to two novel nitrogen mustard derivatives, their preparation method and their application as tumor treatment drugs. 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 drug molecul...
