Problems solved by technology

However, most compounds have low selectivity for G-quadruplexes, and can bind to both single- and double-stranded nucleic acids [T.Ou et al.ChemMedChem2008,3,690-713]
In addition, the optical properties of most compounds do not change significantly after binding to the G-quadruplex, so they cannot be used for the detection of the G-quadruplex structure

Abstract

The invention provides 2,9-bis-styryl substituted phenanthroline compounds specifically combined with G-tetrastrobila-structure nucleic acid and a preparation method thereof, and application of the 2,9-bis-styryl substituted phenanthroline compounds in tumor resistance. The structural formula is disclosed as Formula I. The compounds disclosed as Formula I can quickly judge whether the sample to be detected is G-tetrastrobila-structure nucleic acid by ultraviolet-visible absorption spectrum or fluorescence spectrum. The drug effect test proves that the compounds disclosed as Formula I in vitro have strong inhibiting actions on multiple tumor cell strains. The 2,9-bis-styryl substituted phenanthroline compounds can be used for preparing anticancer drugs.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to 2,9-bisstyrene substituted o-phenanthroline compounds and a preparation method and application thereof. Background technique [0002] G-quadruplex (G-quadruplex) is a nucleic acid sequence rich in guanine (G), through the formation of Hoogsteen base pairing between chains or corresponding G bases in the chain, so that four or four pieces of G-rich nucleic acid A special nucleic acid secondary structure formed by aggregation of fragments [S.Burge et al.Nucleic Acids Res,2006,34,5402-5415]. G-rich sequences are ubiquitous in genomes with important functions, such as telomeres, gene promoter regions, immunoglobulin switch regions, etc. [J.L.Huppert et al.Nucleic Acids Res,2005,33,2908-2916; 2007,35,406- 413; A.K. Todd et al. Nucleic Acids Res, 2005, 33, 2901-2907]. And it is closely related to the formation mechanism of human lifespan, cancer, HIV and other diseases [T.A.Brooks...
