  A Synthetic Dolastatin 10 Analogue Suppresses Microtubule Dynamics, Inhibits Cell Proliferation, and Induces Apoptotic Cell Death

  摘要：

  We have synthesized eight analogues (D1-D8) of dolastatin 10 containing several unique amino acid subunits. Of these agents, D5 was found to be most effective in inhibiting both He La cell proliferation and microtubule assembly in vitro. At low nanomolar concentrations, 135 inhibited the proliferation of several types of cancer cells in culture. D5 bound to tubulin with a dissociation constant of 29.4 +/- 6 mu M. D5 depolymerized microtubules in cultured cells and produced mulitpolar spindles. At its half-maximal inhibitory concentration (15 nM), DS strongly suppressed the dynamics of individual microtubules in live MCF-7 cells. DS increased the accumulation of checkpoint proteins BubR1 and Mad2 at the kinetochoric region and caused G2/M block in these cells. The blocked cells underwent apoptosis with the activation of Jun N-terminal kinase. The results suggested that DS exerts its antiproliferative action by dampening microtubule dynamics.

• Samarium Iodide-Mediated Reformatsky Reactions for the Stereoselective Preparation of β-Hydroxy-γ-amino Acids: Synthesis of Isostatine and Dolaisoleucine
  作者：Christopher G. Nelson、Terrence R. Burke

  DOI：10.1021/jo202091r

  日期：2012.1.6

  The synthesis of β-hydroxy-γ-amino acids via SmI2-mediated Reformatsky reactions of α-chloroacetyloxazolidinones with aminoaldehydes is reported. Diastereoselective coupling is demonstrated to depend on the absolute configuration of the Evans chiral auxiliary employed in the reaction, allowing erythro or threo products to be obtained selectively. The potential utility of the methodology is exemplified
