ST09 is an efficient and low toxicity Curcumin (HY-N0005) derivative. ST09 significantly inhibits cell migration and downregulates the expression of MMP1, MMP2, and Vimentin. ST09 has strong cytotoxicity to breast cancer cells, such as MDA-MB-231, MCF7 and T47D cells. ST09 induces cell apoptosis by upregulating Bax and cleaved caspase-3/9. ST09 can be used in the research of cancer such as breast cancer[1].
