Amino evodiamine derivative and preparation method and application thereof
-
Paragraph 0010; 0014, (2020/09/16)
The invention discloses an amino evodiamine derivative and a preparation method and application thereof. A carboline compound and N-methyl-7-nitro isatoic anhydride are used for preparing a 2-nitro evodiamine derivative, and the 2-nitro evodiamine derivative is reduced to obtain the amino evodiamine derivative. A cytotoxicity experiment is performed by using a CCK-8 method, the anti-proliferationeffect of the compound on breast cancer MDA-MB-231 cells, colon cancer SW620 cells and normal liver LO2 cells is evaluated, and cell apoptosis detection is performed by using FITC/PI double staining;experiments show that compared with evodiamine, the compound 2-NH2-EVO has a very strong inhibition effect on breast cancer cells MDA-MB-231, the IC50 value is 0.79 uM, meanwhile, cell apoptosis can be remarkably induced, and the compound 2-NH2-EVO is expected to be developed into an anti-cancer drug with potential.
Doxorubicin-loaded polymeric micelle as well as preparation method and application thereof
-
Paragraph 0014; 0015, (2020/10/04)
The present invention discloses a doxorubicin-loaded polymeric micelle as well as a preparation method and application thereof. Novel amino evodiamine is adopted to react with polyethylene glycol, a micelle obtained by self-assembly is used as a carrier to load doxorubicin, a prepared mPEG-CO-NH-EVO micelle and a mPEG-CO-NH-EVO-OCH3 micelle have low toxicity to normal hepatocytes so that the two amphipathic polymeric micelles are used as carriers to load DOX to prepare DOX-loaded polymeric micelles, namely a mPEG-CO-NH-EVO/DOX micelle and a mPEG-CO-NH-EVO-OCH3/DOX micelle, and DOX enters hydrophobic shells of the micelles due to the dialysis effect; shapes of the micelles are represented by using a transmission electron microscope and a scanning electron microscope, and the drug loading efficiency and encapsulation efficiency of DOX are tested and calculated by using an ultraviolet spectrophotometer; and finally, evaluating the cytotoxicity by using a CCK-8 method. Shown by cytotoxicity tests, a DOX-loaded polymer has an effect on inhibiting breast cancer cells and particularly has greatly reduced toxicity to the normal hepatocytes.
