Description

technical field [0001] The invention relates to the technical field of biomedicine, relates to an anti-tumor compound, in particular to a diaryl urea compound substituted by an aromatic heterocyclic amide, a preparation method and application thereof. 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. [0003] 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 suppre...
