The DNA binding of BACs was evaluated by DNA thermal denaturation experiment. In the series, the methionine-substituted BACs had the weakest DNA binding, while the lysine-substituted BACs had the highest T(m) values. The abilities of BACs to inhibit the growth of MCF-7, NCI-H460, SF-268, and PC-3 cell lines were determined. l-Met-MAC 16 and l-Lys-MAC 20 were the most potent growth inhibitors. MAC 16 was more cytotoxic than MX, whereas the T(m) of MAC 16 was much lower than that of MX. In contrast to MAC 16, l-Lys-MAC 20 demonstrated higher T(m) than MX. These data suggested that Met-BACs possessed a different pharmacological profile, in which the ability to stabilize DNA is not parallel to the ability to kill cancer cells, from that of AT and MX. The primary mechanism of cytotoxicity for MAC 16 was most likely through TOP2 poisoning. Therefore, MAC 16 may provide a lead for the development of novel generations of anthraquinone-type antitumor agents. ------>tmu_sno=None ------>sno=17189 ------>authors2=Wang HP ------>authors3=Kao PH ------>authors4=Lee O ------>authors5=Chen WR ------>authors6=Chen HW, Guh JH, Chan YL, His CP, Yang MS, Li a TK ------>authors6_c= ------>authors=Hsin LW ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Synthesis, DNA binding, and cytotoxicity of 1,4-bis(2-amino-ethylamino)anthraquinone-amino acid conjugates. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no= ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2008 ------>submit_flag=None ------>publish_month=1 |
