摘要:
Amamistatins A and B are natural products found to have anti-proliferative effects against MCF-7, A549, and MKN45 human tumor cell lines (IC(50) 0.24-0.56 mu M). It was proposed that their activity was due to histone deacetylase (HDAC) inhibition mediated by the N-formyl-N-hydroxy lysine moiety. Amamistatin B fragment analogs were synthesized and screened for biological activity. These compounds were modest HDAC inhibitors and showed antitumor activity against MCF-7 and PC-3 human tumor cells.
