A ligustrazine (TMP) derivative, (E)-2-(2, 4-dimethoxystyryl)-3,5,6-trimethylpyrazine (DLJ14) was synthesized for the improvement of low bioavailability and short half-life of ligustrazine. We have observed potential reversal effects of DLJ14 on adriamycin (Adr)-resistant human myelogenous leukemia
Chemotherapy resistance is a major challenge for breast cancer treatment. It is necessary to elucidate the mechanisms of anthracycline resistance to develop new chemosensitizers for breast cancer. In this study, we explored the effects of ligustrazine (TMP) on reverting anthracycline resistance of
BACKGROUND
Ligustrazine, the active ingredient present in Umbelliferae plant roots used in Chinese medicine, plays a vital role in reversing multidrug resistance in tumors. This study aims to investigate its anticancer activity and underlying mechanisms in human breast cancer cells in vitro and in
OBJECTIVE
We investigated the chemo-sensitization of a ligustrazine derivate, (E)-2-(2, 4-dimethoxystyryl)-3, 5, 6-trimethylpyrazine (DLJ14) on Adriamycin (Adr, Wanle, Shenzhen, China)-resistant human breast cancer (MCF-7/A) cells both in vivo and in vitro.
