  Optimization and Structure–Activity Relationships of Phosphinic Pseudotripeptide Inhibitors of Aminopeptidases That Generate Antigenic Peptides

  摘要：

  The oxytocinase subfamily of M1 aminopeptidases, Consisting of ER aminopeptidase 1 (ERAP1), ER aminopeptidase 2 (ERAP2), and insulin-regulated aminopeptidase (IRAP), plays critical roles in the generation of antigenic peptides and indirectly regulates human adaptive immune responses. We have previously,demonstrated that phosphinic pseudotripeptides can constitute potent inhibitors of this group of enzymes. In this study, we used synthetic methodologies able to furnish a series of stereochemically defined phosphinic pseudotripeptides and demonstrate that side chains at P-1' and P-2' positions are Critical determinants in driving potency and selectivity. We identified low nanomolar inhibitors of ERAP2 and IRAP that display selectivity of more than 2 and 3 orders of magnitude, respectively. Cellular analysis demonstrated that one of the compounds that is a selective IRAP inhibitor can reduce IRAP-dependent but not, ERAP1-dependent cross-presentation by dendritic cells with nanomolar efficacy. Our results encourage further preclinical development of phosphinic pseudotripeptides as regulators of adaptive immune responses.

  在ZnCl 2存在下使用Mg插入合成取代的金刚烷锌试剂及进一步的功能化

  摘要：

  在ZnCl 2存在下通过LiCl介导的Mg插入可以从相应的官能化叔溴开始有效合成金刚烷基锌试剂。高反应性的金刚烷基锌类很容易经历各种各样的功能化，例如Negishi交叉偶联，Cu（I）催化的酰化和烯丙基化，以及1,4-加成反应，从而以预期的产率获得了预期的产物。此外，金刚烷基部分可以作为α-取代基引入对噻吩中，由于更高的亲脂性和防止π堆积而增加了其溶解度。

• 2-Functionalized allyl tris(trimethylsilyl)silanes as radical-based allylating agents
  作者：Chryssostomos Chatgilialoglu、Carla Ferreri、Marco Ballestri、Dennis P. Curran

  日期：1996.8

  Radical allylations with 2-functionalized allyl tris(trimethylsilyl)silanes occur under mild conditions in good to excellent yield provided that the radical precursor and the silane have the appropriate electronic pairing. These reactions offer tin-free altermatives for transformations that are currently conducted with allyl stannanes.

  如果自由基前体和硅烷具有适当的电子配对，则在温和的条件下，以2官能化的烯丙基三（三甲基甲硅烷基）硅烷进行自由基烯丙基化反应会产生良好或极好的收率。这些反应为目前用烯丙基锡烷进行的转化提供了无锡替代品。

  We describe Cu-catalyzed intermolecular alkynylation and allylation of unactivated C(sp3)–H bonds with singly occupied molecular orbital-philes (SOMO-philes) via hydrogen atom transfer (HAT). Employing N-fluoro-sulfonamide as a HAT reagent, a set of substituted alkene and alkyne compounds were synthesized in high yields with good regioselectivity and functional-group compatibility.

  A competing 1,3-rearrangement of allyl stannanes has been demonstrated to occur under the normal thermal homolytic allyl transfer reaction conditions which limits the substitution patterns in these processes; two methacrylyl stannanes are described which allow the transfer of the methacrylyl moiety to alkyl bromides and iodides under mild conditions.
