Abstract

The invention relates to the field of medicinal chemistry, in particular to a garcinia derivative (I), a preparation method thereof and the application of the derivative in pharmacy. The derivative is a structural analogue of a garcinia natural product such as gambogic acid and has the molecular weight which is lower than that of the gambogic acid, and hetero atoms and hydrophilic groups are introduced or further salified, so that the absorbability of a gastrointestinal tract is improved; and the derivative has an antitumor effect and can be used for preparing antitumor medicaments.

Description

technical field [0001] The invention relates to the field of medicinal chemistry, in particular to a class of Garcinia derivatives, a preparation method thereof and an application in pharmacy. The derivative is a structural analogue of gambogic acid, a natural product of the genus Garcinia, has antitumor effect, and can be used for preparing antitumor drugs. Background technique [0002] Gambogic acid, a natural product, is extracted from the colloidal resin secreted after the trunk of the genus Garcinia is split, and is an important anti-tumor active ingredient in the gamboge resin. Studies have shown that gambogic acid can selectively inhibit the growth of transplanted tumors within the effective dose range, and its anti-tumor effect is different from that of general chemotherapy drugs. It can selectively kill a variety of tumor cells, while for normal hematopoietic System and immune function had no significant effect. Gambogic acid can regulate the expression of a varie...
