Abstract
Mutidrug-resistant is a significant clinical problem in the treatmnet of cancer and this resistance has been linked to the cellular expression of multidrug-efflux transporters. The aim of this study was to examine the effects and mechanisms of the new metformin derivative HL156A in human multidrug-resistant cancer cell lines (FADU/PTX, MCF7/ADR and SNU/CIP). HL156A significantly suppressed cell growth and colony formation in a concentration-dependent manner and caused G2/M phase arrest by inhibiting the expression of Cdk1/cyclin B1. HL156A also reduced wound closure/migration and induced cell death in multidrug-resistant cancer cells. We found that HL156A inhibited the expression of MDR1 through inhibiting of HOXC6-ERK1/2 signaling pathway. In addition, treatment of non-lethal dose 20 uM HL156A increased their sensitivity to paclitaxel or doxorubicin in FADU/PTX and MCF7/ADR. Furthermore, the anti-angiogenesis activity of HL156A was verified in chicken chorioallantoic membranes (CAMs). HL156A significantly inhibited angiogenesis in a CAM assay. These results suggest the potential value of the new metformin derivative HL156A as a candidate for a therapeutic modality for the treatment of multidrug resistance cancers.
