  Efficient transformation of 7,14-dihydroxy-ent-kaurenes to novel ent-abietanes having cis-fused α-methylene γ-lactones under Mitsunobu reaction conditions and their cytotoxicities

  摘要：

  Transformation of plant-origin 7,14-dihydroxy-ent-kaurenes to ent-abietanes having a cis-fused alpha-methylene gamma-lactones was accomplished efficiently under the Mitsunobu reaction conditions. The yields of the desired products were apparently influenced by the steric hindrance at C-1. The cytotoxic activity on P388 murine leukemia cells of the ent-abietanes having cis-fused alpha-methylene gamma-lactones produced were assayed. (C) 2014 Elsevier Ltd. All rights reserved.

  A series of rabdokunmin C analogues were prepared and their inhibitory effect on NF-kappa B activation was assayed. One of them, 18-acetyl-12-deoxy-11,12-dehydrorabdokunmin C (16) was found to be a promising candidate for an anti-inflammatory agent. (C) 2011 Elsevier Ltd. All rights reserved.
