Abstract

The invention discloses a class of anti-tumor compounds containing a triazole heterocyclic structure and an application thereof, belonging to the technical field of medicinal chemistry. The compounds containing the triazole heterocyclic structure introduce quintuple 1,2,3-triazole ring in the form of side chains through the amino condensation, bromination, nitrine substitution, link reaction and other reactions on the basis of naphthalimide parent structure, select tetrazolium salt reduction to test 7721 hepatocellular in the experiment of inhibiting proliferation of tumor cells, and also select sulfonyl rhodamine B protein staining method to test MCF-7 breast cancer cells. The experiment results show that the anti-tumor compounds have wide anti-tumor activity and good inhibition effect on the normal growth of tumor cells derived from different tissues of liver cancer, breast cancer and the like.

Description

technical field [0001] The invention relates to a class of anti-tumor compounds containing a triazole heterocyclic structure and applications thereof, belonging to the technical field of medicinal chemistry. Background technique [0002] Naphthalimide compounds that introduce nitrogen-containing heteroatom substituents on the aromatic ring have good anticancer activity, and amonafide (N-(β-dimethylaminoethyl)-3-amino- 1,8-naphthalimide) (Malviya V K, Liu P Y, Alberts D S, et al.Am.J.Clin.Oncol., 1992, 15:41-44.) and mitonafide (N-(β-dimethyl (aminoethyl)-3-nitro-1,8-naphthalimide) (Brana M.F, Santos A., Roldan C.M., et al.Eur.J.Med.Chem.Chim.Ther., 1981,16 , 207-212) has entered phase II clinical trials. The compound can effectively inhibit the growth of tumor cells, and its mechanism of action is to intercalate between the base pairs of DNA, inhibit the synthesis of DNA and RNA, and inhibit topoisomerase II, so as to achieve the purpose of inhibiting tumors. However, in ...
