[0042] denoted as a 1 .

[0043] The complex is prepared by the following steps:

[0044] 1. Synthesize ligand pbi (pbi=2-(1,10-Phenanthrolin-5-yl)-benzo[d]imidazole) to obtain yellow powder: add 0.001mol o-phenylenediamine, 0.001mol 5- Aldehyde o-phenanthroline and 0.002 mol of sodium bisulfite were dissolved in 3 mL of DMF and heated to reflux at 150°C for 6 hours to obtain a brown solution with a small amount of precipitation. Adding 30 mL of water to the reaction solution resulted in a large amount of yellow precipitate, which was filtered with suction, washed with water for several times, and dried in vacuo. 0.255 g of yellow powder was obtained with a yield of 86...

Embodiment 2

[0070] A ruthenium (II) polypyridine complex, the complex is based on 2-(1,10-phenanthroline-5-yl)-benzimidazole) as the main ligand, and the complex is based on 1,10'-o-phenanthrene Roline is the auxiliary ligand, and the chemical formula of the complex is [Ru(phen) 2 pbi] 2+ , the structural formula of the complex is:

[0071] denoted as a 2 .

[0072] The complex is prepared by the following steps:

[0073]1. Synthesize ligand pbi (pbi=2-(1,10-Phenanthrolin-5-yl)-benzo[d]imidazole) to obtain yellow powder: add 0.001mol o-phenylenediamine, 0.001mol 5- Aldehyde o-phenanthroline and 0.002 mol of sodium bisulfite were dissolved in 3 mL of DMF and heated to reflux at 150°C for 6 hours to obtain a brown solution with a small amount of precipitation. Adding 30 mL of water to the reaction solution resulted in a large amount of yellow precipitate, which was filtered with suction, washed with water for several times, and dried in vacuo. 0.255 g of yellow powder was obtained w...

Embodiment 3

[0085] Adopt the preparation method similar to embodiment 1, specifically comprise the following steps:

[0086] 1. Synthesize ligand pbi (pbi=2-(1,10-Phenanthrolin-5-yl)-benzo[d]imidazole) to obtain yellow powder: add 0.001mol o-phenylenediamine, 0.001mol 5- Aldehyde o-phenanthroline and 0.002 mol of sodium bisulfite were dissolved in 3 mL of DMF and heated to reflux at 120°C for 12 hours to obtain a brown solution with a small amount of precipitate. Add 5 times the solution volume of water to the reaction solution, a large number of yellow precipitates are produced, filter with suction, wash the filter cake with water several times, and dry it in vacuum. 0.255 g of yellow powder was obtained with a yield of 86%.

[0087] 2. Add 6mmol ruthenium trichloride (RuCl 3 ·3H 2 O), 6mmol lithium chloride monohydrate, and 12mmol bipyridyl, dissolved in 10ml DMF, heated to reflux at 130°C for 10 hours under the protection of argon to obtain a solid-liquid mixture, cooled to room tem...

Abstract

The invention relates to ruthenium (II) polypyridine complex.The complex uses 2-(1, 10-phenanthroline monohydrate-5-base)-benzimidazole) as the main ligand and 2, 2'-bipyridine or 1, 10'-phenanthroline as the auxiliary ligand, and the chemical formula of the complex is [Ru(bpy)2pbi]2+ or [Ru(phen)2pbi]2+.A preparation method of the complex includes the steps of firstly, preparing pbi; secondly, synthesizing a ruthenium metal compound with the auxiliary ligand group; thirdly, synthesizing the target ruthenium (II) polypyridine complex; fourthly, using silica gel chromatography column separation to obtain the product.The ruthenium (II) polypyridine complex is used for preparing medicine combining with telomere G-quadruplex to increase the stability of the telomere G-quadruplex.Compared with the prior art, the ruthenium (II) polypyridine complex prepared by the method has the advantages that the ruthenium (II) polypyridine complex can recognize, combine and stabilize the telomere G-quadruplex, inhibit telomerase activity and regulate proto-oncogene expression, and a theoretical foundation is provided for anticancer medicine screening.

Description

technical field [0001] The invention relates to metal complexes, in particular to a ruthenium (II) polypyridine complex and its preparation and application. Background technique [0002] Nucleic acid is the material basis of biological inheritance. The research on nucleic acid not only helps us explore the origin of life, but also is particularly important in solving gene-related diseases. In addition to the traditional double helix structure, there are many non-classical configurations of nucleic acids, the most striking of which is the G-quadruplex (G4) structure, mainly because it is an effective target for people to regulate biological functions through chemical interference. point. G4 is a four-stranded nucleic acid structure, which is formed by the accumulation of G-tetrads formed by Hoogsteen pairing between G bases. This assembly phenomenon is very common in G-rich nucleic acid sequences . Since G-rich sequences are abundant in many functional gene regions (such ...
