Abstract

The invention relates to a 5-site or 6-site substituent naphthalimide compound and antitumor applications thereof, which belongs to the fine chemical field. The compound is characterized in that various aliphatic amidogen, heterocyclic amidogen, aryl and Ar aryl are respectively introduced into the 5-site or 6-site of the naphthalimide by a nucleophilic substitution reaction to obtain small molecule compound similar to a lead compound amonafide structure. The small molecule compound has obvious inhibiting activity in vitro test on Hela and P388D1, and wherein, some compounds have stronger cytotoxicity than the amonafide under the same test conditions. In addition, the structures of the compounds take on diversity; the compounds without acetylation sites can be prevented from having the side effect similar to the amonafide; the other compounds with the acetylation sites can be prevented from having the side effect by personalized administration, therefore, the compound has medical application prospect in curing diseases related to tumors.

Description

technical field [0001] The invention relates to a class of 5- or 6-substituted naphthalimide compounds and anti-tumor applications, belonging to the field of fine chemicals. Background technique [0002] Cancer is a serious threat to human health and life safety, and the development of highly effective and low-toxic antitumor drugs is a very active research direction in the field of medical chemistry. Naphthalimide compounds are a class of compounds with good anticancer activity, among which amonafide (N-(β-dimethylaminoethyl)-3-amino-1,8-naphthoyl imine)] and mitonafide (N-(β-dimethylaminoethyl)-3-nitro-1,8-naphthalimide)] have entered phase II clinical trials (Brana M.F. , Santos A., Roldan C.M., et al. Eur. J. Med. Chem. Chim. Ther., 1981, 16, 207). Such compounds can intercalate between base pairs of DNA, inhibit the synthesis of DNA and RNA, and inhibit topoisomerase II, thereby achieving the purpose of inhibiting tumors. [0003] However, in clinical application, it...
