Boehmeriasin A as new lead compound for the inhibition of topoisomerases and SIRT2
摘要:
Two synthetic approaches to boehmeriasin A are described. A gram scale racemic preparation is accompanied by an efficient preparation of both the pure enantiomers using the conformationally stable 2-piperidin-2-yl acetaldehyde as starting material. The anti-proliferative activity in three cancer cell lines (CEM, HeLa and L1210) and two endothelial cell lines (HMEC-1, BAEC) indicates promising activity at the nanomolar range. Topoisomerases and SIRT2 are identified as biological targets and the experimental data has been supported by docking studies. (C) 2015 Elsevier Masson SAS. All rights reserved.

A concise and efficient route involving Parham-type cycliacylation as the key step has been used to synthesize phenanthroquinolizidine alkaloids 1a-c and 2a-c. Among the products, 1b-(S), 1b-(R), 2a-(14S,15S), 2a-(14aR,15R), and 2b were synthesized for the first time. (C) 2010 Elsevier Ltd. All rights reserved.
