[0060] 2) Preparation of target derivatives of the present invention

[0061]

[0062] In general formula 1), starting from commercially available raw material brominated polycyclic aromatic hydrocarbons, according to the aromatic alkynylation method and conditions reported in the literature (Angewandte Chemie-International Edition, 2005, vol.44, #39p.6362-6366 ; Chemistry-A European Journal, 1999, vol.5, #11p.3366-3381; Journal of Organic Chemistry, 1999, vol.64, #8p.2704-2710), can successfully prepare alkynyl-substituted polycyclic aromatic hydrocarbons.

[0063] The coupling reaction between brominated polycyclic aromatic hydrocarbons and trimethylethynyl silane is generally carried out in the presence of metal palladium catalysts and copper salts. The metal palladium catalysts that can be used include tetrakis (triphenylphosphine) palladium, bistriphenylphosphine P...

Abstract

The invention discloses the application of a saccharide coupled-1, 2, 3-triazole substituted polycyclic aromatic hydrocarbon derivative in the preparation of an anti-cancer drug. The structure of thesaccharide coupled-1, 2, 3-triazole substituted polycyclic aromatic hydrocarbon derivative is shown as the formula (I). A pharmacology experiment proves that the saccharide coupled-1, 2, 3-triazole substituted polycyclic aromatic hydrocarbon derivative has different degrees of inhibiting effects on lung cancer (H460), gastric cancer (HGC27), myeloma (H929), cervical cancer (Hela), liver cancer (HepG2), prostatic cancer (DU145) and colon cancer (HT29).

Description

technical field [0001] The invention belongs to the technical field of biopharmaceutical chemical synthesis, and in particular relates to the use of sugar-coupling-1,2,3-triazole-substituted polycyclic aromatic hydrocarbon derivatives in the preparation of anticancer drugs. Background technique [0002] PAHs are generally classified as chemicals with chronic toxicity. As π-electron-dense polycyclic aromatic hydrocarbon derivatives, they can interact with DNA macromolecules, causing DNA damage, such as forming DNA adducts, inducing DNA strand breaks, and the like. DNA strand break is an important type of DNA damage. When the base pairs in the DNA chain of cancer cells are broken or melted due to the insertion of π-electron-dense polycyclic aromatic hydrocarbon compounds, cancer cells cannot continue to replicate DNA leads to apoptosis. For example, there are many studies and reports (J.Med.Chem.1997,40,3734-3738; J Immunol.2007Dec 1; 179(11):7415- 7423; Drug Discov Ther. 2...
