Abstract

The invention discloses a Eudistomins Y derivative with anti-tumor activity as well as a preparation method and application of the Eudistomins Y derivative. A tryptamine derivative (i) is used as a raw material and is subjected to a feeding reaction with acetophenone derivatives (ii), I2 and H2O2 to obtain a compound represented by a general formula (iii), and the compound represented by the general formula (iii) is subjected to a feeding reaction with R-X and K2CO3 according to the molar ratio of 1:(2-6):(2-6) to obtain a compound represented by a general formula (I). The invention provides the Eudistomins Y derivative represented by a general formula (I) and a medically acceptable salt thereof. The Eudistomins Y derivative has the antitumor activity, and is obviously superior to an Eudistomin Y1 prototype compound in the aspect of inhibiting tumor cell proliferation; compared with the non-fluorescence activity of a natural Eudistomins Y compound, the Eudistomins Y derivative represented by the general formula (I) provided by the invention has a fluorescence characteristic and can effectively trace the distribution of the Eudistomins Y derivative in cells and tissues.

Description

technical field [0001] The invention relates to the fields of organic synthesis and medicinal chemistry, in particular to a new class of Eudistomins Y derivatives, a drug combination containing them, a preparation method thereof, and an application thereof in the field of antitumor. Background technique [0002] At present, the incidence of cancer is increasing year by year, and it has become one of the major diseases that threaten human health and even life. Chemotherapy is a common and effective means of tumor treatment in clinical practice. However, due to the adverse reactions of traditional drugs, individual differences in drug action and drug resistance, the design and development of innovative anti-tumor drugs has become a major challenge in the global drug market. [0003] Due to the complexity of the living environment of marine organisms and the diversity of species, the natural products extracted from them have many new structural skeletons, unique chemical struct...
