  Synthesis and tubulin-binding properties of new allocolchicinoids

  摘要：

  Allocolchicinoids with B- and C-ring variations were synthesized using sequential enyne-metathesis/Diets-Alder reactions (A -> AB -> ABC approach) and evaluated for their inhibitory effect on tubulin assembly in vitro. (-)-Allocolchicine 11 with methyl ester at C10 and (+/-)-cyclopropyl allocolchicinoid 32 exhibit similar activity than (-)-colchicine (1), probably derived from a similar flexibility in the biphenyl system. The presence of methyl ester at C10 led to a little loss in potency in comparison with the series with methyl ester at C9. A complete loss of activity was observed for allocolchicine 9 with methyl ester at C11. (C) 2010 Elsevier Inc. All rights reserved.
