  Design, Synthesis, and Optimization of Novel Epoxide Incorporating Peptidomimetics as Selective Calpain Inhibitors

  摘要：

  Hyperactivation of the calcium-dependent cysteine protease calpain 1 (Call) is implicated as a primary or secondary pathological event in a wide range of illnesses and in neurodegenerative states, including Alzheimer's disease (AD). E-64 is an epoxide-containing natural product identified as a potent nonselective, calpain inhibitor, with demonstrated efficacy in animal models of AD. By use of E-64 as a lead, three successive generations of calpain inhibitors were developed using computationally assisted design to increase selectivity for Call. First generation analogues were potent inhibitors, effecting covalent modification of recombinant Call catalytic domain (Call(cat)), demonstrated using LC-MS/MS. Refinement yielded second generation inhibitors with improved selectivity. Further library expansion and ligand refinement gave three Call inhibitors, one of which was designed as an activity-based protein profiling probe. These were determined to be irreversible and selective inhibitors by kinetics studies comparing full length Call with the genera l cysteine protease papain.

• Backbone Modification of β-Hairpin-Forming Tetrapeptides in Asymmetric Acyl Transfer Reactions
  作者：Peng Chen、Jin Qu

  日期：2011.5.6

  acyl transfer reaction of trans-2-(N-acetylamino)cyclohexan-1-ol (krel = 28). Through our backbone modification strategy, thioamide and sulfonamide as the isosteres of amide were introduced in the β-hairpin secondary structure. The thioxo peptides also adopt β-hairpin conformations as the oxopeptide supported by the combined use of NMR, IR, and X-ray techniques. Thioxo tetrapeptide 14 formed a more

  合成的寡肽作为酶的模拟物已被越来越多地用作不对称反应的催化剂，但是仍然需要相对低分子量的高效寡肽催化剂。在本文中，我们展示了形成β-发夹的四肽4的构象工程，该构象是Miller小组首次报道的，它是反式-2-（N-乙酰氨基）环己-1-醇（不饱和）的不对称酰基转移反应的催化剂（ķ相对= 28）。通过我们的主链修饰策略，将硫代酰胺和磺酰胺作为酰胺的等排物引入了β-发夹二级结构中。thioxo肽还采用β-发夹结构作为氧肽，并结合使用NMR，IR和X射线技术来支持。硫氧四肽14形成了更受约束的β-发夹构象，因此在同一反应中提供了更高的对映选择性（k rel = 109）。此外，四肽的构象变化的检查8在所述的质子化Ñ π -methylhistidine部分提供了证据来解释在不对称酰基转移反应的催化效率的变化。

  Two is better than one: We demonstrate the viability of an organocatalytic reaction sequence along a short peptide backbone that carries two independent catalytic functionalities, which allow the rapid, one‐pot acylative desymmetrization and oxidation of meso‐alkane‐1,2‐diols to the corresponding acetylated acetoins with good yields and enantioselectivities (see scheme).

We identified catalysts that invert site-selectivity compared to N-methylimidazole, which was used to determine the intrinsic reactivity, for 4,6-O-protected glucopyranosides (trans-diols) as well as 4,6-O-protected mannopyranosides (cis-diols). The reaction yields up to 81% of the inherently unfavored 2-O-acetylated products with selectivities up to 15:1 using mild reaction conditions. We also
