Description
Technical Field
The invention belongs to the technical field of biological medicines, and particularly relates to an indolizine chromophoric ketone compound with anti-tumor activity, and a preparation method and application thereof.
Background
Both natural and synthetic heteromultimers generally exhibit biological activity. Indolizines and chromones are important nitrogen-containing heterocycles, high in content in many natural products and bioactive compounds, which possess a wide range of biological activities, such as antibacterial, antitumor, antioxidant, anticonvulsant, anti-inflammatory, and HIV inhibitory activity.
Chromones and indolizines are considered as structurally modified dominant scaffolds for the design of new compounds with potential pharmacological activity, particularly in the areas of neurodegenerative, inflammatory and infectious diseases, as well as diabetes and cancer. In addition, the use of chromones in the treatment of asthma has also been widely explored, mainly as bronchodilators. During the drug development process, sodium keletonate (DSCG, shown in a formula I) and pranlukast (pranlukast, shown in a formula II) are finally found, and are respectively useful drugs for treating mild-moderate asthma and allergic rhinitis. The indolizine is more and more concerned by people as a key pharmacophore for discovery and research of various small molecular drugs (as shown in formulas III and IV), and shows good antitumor activity.
Since chromone and indolizine show good pharmacological activity and potential pharmaceutical value, people synthesize many compounds with chromone and indolizine frameworks, but the structures containing the two dominant frameworks are rarely reported, which attracts the attention of many scientific researchers at home and abroad. Then some indolizine chromogens are synthesized (shown as formula five and formula six).
In 2003, Deevi Basavaiah et al realized the construction of indolizine chromophoric ketone compound frameworks by Baylis-Hillman reaction, which is the first report on the synthesis of indolizine chromophoric ketone compounds, see reaction formula I:
in 2010 Yi-Chen Lee et al, using thermal and microwave-assisted cyclization to synthesize indolizine chromogens, see reaction formula II:
in conclusion, the indolizine chromocor compounds are compounds with potential medicinal value, the synthesis and pharmacological activity of the compounds are always the focus of attention of researchers, the research on the indolizine chromocor isomeric derivatives is relatively less, only one indolizine chromocor compound is reported at present, and the research on the pharmacological activity of the indolizine chromocor compounds is more rarely reported. Therefore, it is very important to synthesize a new indolizine chromogen ketone compound and research the pharmacological activity of the compound.

TABLE 1 inhibition of KBV and MKN-45 tumor cells by examples 1-57
As can be seen from Table 1, examples 1-57 showed some inhibition of the proliferation of both KBV and IMKN-45 tumor cells. Examples 1, 27, 41, 42, 46 and 48 have strong inhibition effects on two tumor cells, wherein examples 1 and 41 show certain selectivity, and the inhibition effect on human oral epidermoid carcinoma cells KBV is higher than that on human gastric cancer cells MKN-45; example 46 showed strong inhibition of both KBV and IMKN tumor cells. The six embodiments show stronger inhibition effect on the increment of two tumor cells, and can be used as a drug lead compound for preparing subsequent antitumor drugs; the compounds other than the above six compounds do not have strong inhibitory activity against the two cancer cells, but exhibit a certain inhibitory activity, and can provide quantitative effects on the compounds for the development of new drugs in the future.
The foregoing description of specific embodiments of the present invention has been presented.
