Abstract

The invention relates to a naphthalimide derivative and an application thereof.The naphthalimide derivative is of the structure in the formula I or the formula II.The aphthalimide derivative shows obvious inhibitory activity for proliferation of multiple tumor cells such as HCT-116 cells, HepG2 cells, K562 cells and SMMC-7721 cells, and lung metastasis of tumors can be effectively inhibited in the body.

Description

Technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a naphthimide derivative in which an aminonaphthylene ring is modified with a polyamine and alkane chain, and a preparation method and application thereof. Background technique [0002] Naphthimide is a kind of anti-cancer agent that has been proved to have broad application prospects. Many naphthalimide derivatives (such as DMP-840, Elinafide, Amonafide) have entered clinical phase I and phase II trials. But most of them were abandoned due to various side effects such as bone marrow suppression, dose limitation, etc. The representative drug Amonafide is a drug that combines cytarabine in patients with acute myelogenous leukemia and is undergoing clinical phase III trials. Its side effects include bone marrow suppression, vomiting, skin rash, and moderate phlebitis. The cause of this side effect may be that aminonafet is easily acetylated by the NAT2 enzyme in the body ...
