Synthesis of Bioactive Sesterterpenolides from ent-Halimic Acid. 15-Epi-ent-cladocoran A and B
摘要:
The bioactive sesterterpenoid gamma-hydroxybutenolides 15,18-bisepi-ent-Cladocoran A and B, 1 and 2, and 15-epi-ent-Cladocoran A and B, 57 and 55, were synthesized from ent-halimic acid. The synthesized sesterterpenolids 2, 55, 57, and 59 inhibited cellular proliferation (IC50 congruent to 2 muM) of a number of human leukaemic and solid tumor cell lines.
