The invention discloses an alkynylation dihydroartemisinic acid probe, a biotin-dihydroartemisinic acid probe and a preparation method and application of the alkynylation dihydroartemisinic acid probe. The structural formula of the alkynylated dihydroarteannuic acid is as shown in formula 1. And a'biotin-dihydroartemisinic acid 'probe structure is constructed. And co-incubating the probe and a cell lysis solution, co-incubating a lysis solution-probe mixed solution and streptavidin magnetic beads, and eluting to obtain the drug-specific binding protein. According to the invention, the action target of dihydroartemisinin in disease treatment can be quickly, simply and conveniently found.

The invention discloses an active oxygen response type polymer prodrug micelle, and further discloses a polymer prodrug micelle loaded with oridonin or dihydroartemisinin and a polymer prodrug micelle loaded with the oridonin and the dihydroartemisinin at the same time. The invention further provides a preparation method of the polymer prodrug micelle. The ORI and DHA co-loaded active oxygen responsive polymer prodrug micelle provided by the invention can significantly improve the water solubility and biocompatibility of ORI and DHA, can effectively eliminate reduced glutathione in gastric cancer cells AGS cells and amplify active oxygen, and finally causes the generation of a large amount of lipid peroxides, thereby killing tumor cells and inducing cell ferroptosis, and has a good application prospect. And finally, tumor proliferation is inhibited.

Dihydroartemisinin (“DHA”) derivatives that contain a stereospecific C-10 ether linkage and an aryl pharmacophore moiety are disclosed. In some forms, the DHA derivatives possess anticancer properties that are comparable to or better than the parent DHA and / or an existing anticancer drug (e.g., Cisplatin), and are useful in anticancer treatments (such as ovarian cancer and colon cancer). Methods of synthesizing the DHA derivatives that are cost effective are disclosed. Methods of using the DHA derivatives for treating a cancer, such as ovarian cancer and / or colon cancer, in a subject in need thereof are also disclosed.
