Abstract

The invention discloses a series of new 6-hydroxyloxoisoaporphine rare earth complexes, having a structural general formula as shown in specification, wherein Ln is La, Ce, Pr, Nd, Sm, Eu, Gd, Tb or Dy. The complexes are synthesized from 6-hydroxyloxoisoaporphine and the rare earth metal nitrates (Ln(NO3)3.xH2O as raw materials through a heating or reflux reaction. According to the complexes and the synthetic method and application thereof disclosed by the invention, the proliferation inhibition activity of the complexes to a plurality of human tumor cell strains such as SK-OV-3, SK-OV-3 / DDP and T-24 is investigated, and results indicate that all of the complexes have remarkable antitumor activity in vitro; in particular, the 6-hydroxyloxoisoaporphine lanthanum complex has extremely remarkable activity to cervical cancer cells SK-OV-3; in addition, apart from the 6-hydroxyloxoisoaporphine europium complex, the other complexes all have a good inhibition effect on human ovarian cancer / cis-platinum persisters SK-OV-3 / DDP.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a rare earth complex of 6-hydroxyloxidized isoaporphine and its synthesis method and application. Background technique [0002] Cancer and cardiovascular and cerebrovascular diseases have become two major diseases that seriously endanger human life and health. The development of new anticancer drugs and the study of their mechanism of action have always been a hot spot in the chemical research of anticancer drugs, which has extremely important practical significance. [0003] As a research hotspot in the new discipline of inorganic medicinal chemistry, the extensive preliminary research on inorganic complex drugs provides broad prospects for the development of such new metal-based anticancer agents. Platinum anticancer agents are the most commonly used inorganic anticancer drugs at present, and have quite good curative effects on various cancers. However, due to the high toxic...
