The invention discloses a series of aminodithioformate compounds, a preparation method therefor and use of aminodithioformate compounds in preparation of antitumor drugs. Through carrying out activity screening on a micromolecular compound
library, a novel
structure type of PKM2 inhibitors are discovered from the micromolecular compound
library, and a series of aminodithioformate compounds with a structure represented by a general formula I shown in the description are designed and synthesized according to the inhibitors. Proven by
enzyme activity tests, the compounds have remarkable superior PKM2 inhibiting activity and selectivity to those of currently available PKM2 inhibitors. Through separately carrying out killing effect test on
pyruvate kinase M2 and M2 subtypes and four kinds of tumor
cell lines, i.e., MCF-7, HCT116,
Hela and H1299 by using the compounds disclosed by the invention, activity tests prove that the compounds have a remarkable tumor
cell proliferation inhibiting action.
