Chemoenzymatic synthesis and cytotoxicity of oenanthotoxin and analogues
摘要:
We developed a synthetic scheme for the synthesis of naturally occurring (14R)-oenanthotoxin and several analogs. Key-steps of this synthesis were an efficient homo-coupling of alkynes and a chemoenzymatic resolution of racemic oenanthotoxin using novozyme 435 and vinyl acetate. The compounds were screened for their cytotoxic activity using a photometric sulforhodamine B assays and several human tumor cell lines. Oenanthotoxin and many derivatives thereof were cytotoxic to tumor cell lines as well as to non-malignant mouse fibroblasts. The highest activity was determined for human ovarian cancer cells A2780 with EC50 = 3.8 mu M. (C) 2015 Elsevier Ltd. All rights reserved.
