Abstract

The invention discloses novel aminodithioformate compounds, and a preparation method and application thereof, belonging to the field of pharmaceutical chemistry. The structure of the compounds is disclosed as formula I. The research proves that the compounds are PKM2-targeted and are an excitant of PKM2, and also detects that the compounds can generate the antineoplastic action by preventing the PKM2 from entering the karyons. The compounds have favorable antineoplastic action, and have favorable selectivity for tumor cells. Therefore, the compounds can be used as an antineoplastic drug, and have wide application value.

Description

technical field [0001] The present invention relates to compounds and their preparation methods and applications, in particular to novel carbamodithiocarbamate compounds and their preparation methods and applications. These compounds are a new class of PKM2 agonists and can be used as antitumor drugs, belonging to Medicinal Chemistry field. Background technique [0002] Anticancer drug research has always been one of the hot spots in drug research all over the world. At present, there are many effective anti-tumor drugs, but there are few anti-tumor drugs with good efficacy and low side effects. Therefore, the key problem to be solved in the current research on anti-tumor drugs is to find anti-tumor drugs with good curative effect and low side effects. Taking advantage of the difference between tumor cells and normal cells in the metabolic process, selectively interfering with the key links in the metabolic process of tumor cells, it is possible to achieve the purpose of i...
