Anti-metastatic Activity of Curcumin Analog Pentagamaboronon-0-Sorbitol Against HER2-overexpressed MCF-7 Breast Cancer Cells

[摘要] Breast cancer with Human Epidermal Growth Factor Receptor (HER)2 overexpression increases tumor progession and lead to metastasis, which is primarily cause of mortality in breast cancer. Pentagamaboronon-0 Sorbitol (PGB-0-So) is an aquoeous formulation of curcumin analog, PGB-0, with sorbitol. This compound has been developed as an anti-cancer chemotherapeutic agent and a boron carrying pharmaceutical for boron neutron capture therapy (BNCT). The aims of this study are to investigate antimetastatic activities of PGB-0-So against HER2-overexpressed MCF-7 breast cancer (MCF-7/HER2) cells. The MTT cytotoxicity assay of PGB-0-So exhibited cytotoxic effect with an IC50 value of 35 μM. The testing of anti-migration activity using the scratch wound healing assay demonstrated that PGB-0-So inhibited the closure of the wound on MCF-7/HER2 cells compare to the control. Furthermore, PGB-0-So was able to suppress matrix metalloproteinase (MMP)-9 activities, based on the gelatin zymography assay. In conclusion, PGB-0-So has potency to be developed as an anti-cancer agent against metastatic breast cancer.
