Embodiment 1

[0035] In the structural formula of the cyclosuccinamide compound with antitumor activity, R 1 for hydrogen, R 2 For F, prepared by the following steps (see figure 1 ):

[0036] 1) Preparation of 7-bromoquinazolin-4(3H)-one (compound 2) by cyclization reaction of 2-amino-4-bromobenzoic acid (compound 1) and formamide

[0037] Dissolve 5.0g (23.14mmol) of 2-amino-4-bromobenzoic acid in 80ml (2.01mmol) of formamide, and react for 1.45h under nitrogen protection at 150°C and a microwave power of 300W. After the reaction, the The reaction solution was added to ice water, extracted 3-4 times with ethyl acetate, and the extracted organic phase was washed with saturated sodium bicarbonate solution and saturated brine successively, then dried with anhydrous sodium sulfate, and then spin-dried to obtain a reddish-brown residue , the reddish-brown residue was separated by chromatography to obtain 1.89 g of reddish-brown solid 7-bromoquinazolin-4(3H)-one with a yield of 36.3%.

Abstract

The invention provides a cyclobutane-diamide compound with antitumor activity and a preparation method and application thereof. The structure formula of the compound is shown in the description, wherein R1 and R2 are hydrogen, alkane groups or halogen groups. The compound has very good inhibitory activity for VEGFR-2 kinase and can cut off an inductive signal channel of the VEGFR-2 kinase and restrain hyperplasia and migration of tumor cells by restraining the activity of the VEGFR-2 kinase, and therefore the compound can be applied to preparation of antitumor drugs. The preparation method of the compound has the advantages that raw materials are easy to get, reaction conditions are mild, operation is easy in the reaction process, and adopted reagents are low in price.

Description

technical field [0001] The invention belongs to the technical field of biomedicine and relates to an antitumor compound, in particular to a cyclosuccinamide compound with antitumor activity and its preparation method and application. Background technique [0002] Malignant tumors, as one of the largest public health problems in the world, have greatly endangered human health and will become the number one killer of human beings in the new century. Malignant tumors are no longer just a serious disease in developed industrial countries, and developing countries are facing a greater burden of disease. Chemotherapy, as one of the important means of treating tumors, has undergone tremendous development and progress in the past three decades, and a large number of clinical antitumor drugs with different mechanisms of action have been obtained. However, antineoplastic drugs also have many adverse reactions, such as hair loss, vomiting, bone marrow suppression, rapid drug resistanc...
