  摘要：

  Modulation of Hsp90 (heat shock protein 90) function has been recognized as an attractive approach for cancer treatment, since many cancer cells depend on Hsp90 to maintain cellular homeostasis. This has spurred the search for small-molecule Hsp90 inhibitors. Here we describe our lead optimization studies centered on the purine-based Hsp90 inhibitor 28a containing a piperidine moiety at the purine N9 position. In this study, key SAR was established for the piperidine N-substituent and for the congeners of the 1,3-benzodioxole at C8. These efforts led to the identification of orally bioavailable 28g that exhibits good in vitro profiles and a characteristic molecular biomarker signature of Hsp90 inhibition both in vitro and in vivo. Favorable pharmacokinetic properties along with significant antitumor effects in multiple human cancer xenograft models led to the selection of 28g (MPC-3100) as a clinical candidate.

  A facile palladium-catalyzed synthesis of acridines has been realized by consecutive C=C double bond formation and C–N cross-coupling. A variety of functionalized acridines can be accessed from easily available o-dihalobenzenes and N-tosylhydrazones in a single operation. This one-pot protocol has a wide scope with respect to both coupling partners, and provides an efficient route to functionalized

  straightforward and efficient alumination of functionalized arenes by using the frustrated Lewis pair Et3Al and TMPMgCl⋅LiCl (TMP=2,2,6,6‐tetramethylpiperidyl) has been developed. In particular, halogenated electron‐rich aromatics can be smoothly functionalized by using the frustrated Lewis pair Et3Al and TMPMgCl⋅LiCl. Compared with previously described alumination methods, this procedure avoids extensive cooling

  通过使用路易斯受挫的Et一对官能化芳烃的一种直接和高效的脱铝3 Al和TMPMgCl ⋅的LiCl（TMP = 2,2,6,6-四甲基）已经被开发出来。特别地，卤代的富电子的芳族化合物可以顺利地通过使用路易斯受挫的Et一对官能化3 Al和TMPMgCl ⋅的LiCl。与先前描述的铝化方法相比，此过程避免了广泛的冷却，也避免了碱的过量使用。这种原位方法已被证明是最实用的方法，可对具有敏感官能团（CONEt 2，CO 2 Me，CN，OCONMe 2）或卤素（F，Cl，Br，I）。生成的芳族铝酸盐通过NMR光谱进行表征，在金属化成锌后进行烯丙基化，酰化和钯催化的交叉偶联反应。结果表明，用于金属转移的锌盐的性质至关重要。因此，与ZnCl 2（2当量）相比，使用Zn（OPiv）2（2当量； OPiv =新戊酸酯）使得随后的淬灭反应仅需稍微过量的亲电子试剂（1.2当量）即可进行，并提供了有趣的功能化芳烃收率高。
