Analogues of trichosтatin a and trapoxin B as histone deacetylase inhibitors
摘要:
Inhibitors of histone deacetylase are potent inducers of differentiation and bear considerable potential as drugs for chemoprevention and treatment of cancer. So far only complex natural products and a few synthetic congeners have been identified as specific inhibitors. We have prepared a set of simple analogues in as little as four synthetic steps that have inhibitory potencies in the range of known cyclotetrapeptide inhibitors. These compounds are interesting leads for the design of potent inhibitors of histone deacetylase. (C) 1997 Elsevier Science Ltd.
Inhibitors of Histone Deacetylase Suppress the Growth of MCF-7 Breast Cancer Cells
摘要:
Inhibitors of histone deacetylase are attracting increasing interest due to their influence on transcription, differentiation, and apoptosis. We have investigated two synthetic inhibitors 3 and 4 of histone deacetylase and the natural product inhibitor trichostatin A for their ability to suppress of MCF-7 breast cancer cells and here present complete and improved synthetic procedures. The compounds show a dose dependent inhibition of growth with the activities in the low micromolar and nanomolar range. Trichostatin shows cytocidal effects at 100 nM and still has activity comparable to cisplatin (0.5 mu M) at 10 nM. Whereas the synthetic inhibitor 3 has cytocidal activity at 10 mu M compound 4 shows a maximum of 40% growth suppression at that concentration.
