Abstract

The invention discloses a 6-fructosamine-4-arylamidoquinazoline derivative with the structural formula of formula I or a pharmaceutically acceptable salt thereof, and relates to a preparation method and a purpose of above compounds. According to the invention, fructose is connected to a 4-arylamidoquinazoline derivative, so the water solubility of the compounds and the selectivity of the compounds to tumor cells are improved.

Description

technical field [0001] The invention belongs to the field of antineoplastic drugs, and in particular relates to a 6-fructosamino-4-arylaminoquinazoline derivative and its application in synthesis and preparation of antineoplastic drugs. Background technique [0002] World Health Organization (WHO) officials warned at the 2008 International Oncology Annual Meeting held in Atlanta, USA that by 2010 cancer will replace cardiovascular disease as the disease with the largest number of deaths in the world. The previously dreaded cardiovascular diseases (stroke and myocardial infarction) will take a backseat to the second place. According to WHO statistics, in 2007, there were as many as 12 million newly diagnosed tumor patients in the world, and in the past few years, more than 7 million patients worldwide died of cancer every year. This figure is very close to the number of people who die from acute cardiovascular disease. At present, the treatment methods for tumors are still ...
