  摘要：

  据报道，在温和的反应条件下，用易于获得且稳定的氨硼烷（AB）作为还原剂，将酰胺进行的首次B（C 6 F 5）3催化脱氧还原为相应的胺。该无金属方案可轻松获得各种结构多样的胺产品，且收率高至优异，并且对各种官能团（包括对还原敏感的官能团）均具有良好的耐受性。该新方法也适用于手性酰胺底物，而不会破坏对映体的纯度。BF 3  OEt 2助催化剂在该反应中的作用是通过酰胺-硼加合物的原位形成来活化酰胺羰基。

  Zn²⁺-Chelating Motif-Tethered Short-Chain Fatty Acids as a Novel Class of Histone Deacetylase Inhibitors

  摘要：

  Among various classes of histone deacetylase (HDAC) inhibitors, short-chain fatty acids exhibit the least potency, with IC50 in the millimolar range. We rationalized that this weak potency was, in part, attributable to their inability to access the zinc cation in the HDAC active-site pocket, which is pivotal to the deacetylation catalysis. We thus explored the structural optimization of valproate, butyrate, phenylacetate, and phenylbutyrate by coupling them with Zn2+-chelating motifs (hydroxamic acid and o-phenylenediamine) through aromatic W-amino acid linkers. This strategy has led to a novel class of Zn2+ -chelating, motif-tethered, short-chain fatty acids that exhibited varying degrees of HDAC inhibitory potency. One hydroxamate-tethered phenylbutyrate compound, N-hydroxy-4-(4-phenylbutyrylamino)benzamide (HTPB), displayed nanomolar potency in inhibiting HDAC activity. Exposure of several cancer cell lines to HTPB at the submicromolar level showed reduced cell proliferation accompanied by histone hyperacetylation and elevated p21(WAF/CIPI) expression, which are hallmark features associated with intracellular HDAC inhibition.

  We previously discovered steroidal NPC1L1 ligands by using a novel cell-based assay that employs pharmacological chaperone effect as a readout. Those steroid derivatives bound to a site different from both the sterol-binding domain and the ezetimibe-binding site, implying that they may be a novel class of NPC1L1 inhibitors with a distinct mode of action. As an extension of that work, we aimed here

  Niemann-Pick C1样1（NPC1L1）是一种肠道胆固醇转运蛋白，已知是胆固醇吸收抑制剂依泽替米贝的靶标。我们以前通过使用一种新的基于细胞的测定法发现了甾体NPC1L1配体，该测定法采用药理分子伴侣效应作为读数。这些类固醇衍生物与不同于固醇结合域和依泽麦布结合位点的位点结合，这意味着它们可能是一类具有独特作用方式的新型NPC1L1抑制剂。作为这项工作的延伸，我们的目标是通过使用相同的分析方法筛选聚焦于肝X受体（LXR）的配体库，从而找到非甾体NPC1L1配体，这些配体可能比甾体配体更适合临床应用。将氧固醇识别为内源性配体的核受体。

  ruthenium(II)‐catalyzed deoxygenative transfer hydrogenation of amides to amines using HCO2H/NEt3 as the reducing agent is reported for the first time. The catalyst system consisting of [Ru(2‐methylallyl)2(COD)], 1,1,1‐tris(diphenylphosphinomethyl) ethane (triphos) and Bis(trifluoromethane sulfonimide) (HNTf2) performed well for deoxygenative reduction of various secondary and tertiary amides into the corresponding

  首次报道了使用HCO 2 H / NEt 3作为还原剂的钌（II）催化的酰胺脱氧转移胺成胺。催化剂体系由[Ru（2-甲基烯丙基）2（COD）]，1,1,1-三（二苯基膦甲基）乙烷（triphos）和双（三氟甲烷磺酰亚胺）（HNTf 2）在将各种仲酰胺和叔酰胺脱氧还原成相应的胺方面表现出色，选择性极好，并且对包括还原敏感基团在内的官能团表现出很高的耐受性。氢源和酸助催化剂的选择对于催化至关重要。机理研究表明，通过借入氢对原位生成的醇和胺进行还原胺化是主要途径。

  reported nonpeptidic angiotensin II (AII) receptor antagonists DuP753 (1) and Exp 7711 (2), we have designed and investigated novel substituted benzimidazoles. Systemic variation of several substituents at the benzimidazole ring positions 4-7 led to the finding that substitution in position 6 with acylamino groups results in highly active AII antagonists. Compounds with 6-membered lactam or sultam substituents

  从最近报道的非肽类血管紧张素II（AII）受体拮抗剂DuP753（1）和Exp 7711（2）开始，我们设计并研究了新型取代的苯并咪唑。苯并咪唑环位置4-7上几个取代基的系统变化导致发现，位置6被酰基氨基取代会产生高活性的AII拮抗剂。在苯并咪唑的6位上具有6元内酰胺或sultam取代基的化合物在低纳摩尔范围内显示受体活性，但当口服给予大鼠时仅具有弱活性。相反，用碱性杂环类似地取代苯并咪唑部分产生有效的AII拮抗剂，其在口服后也被很好地吸收。该系列中活性最高的化合物33（BIBR 277），被选为临床发展的候选人。在分子模型研究的基础上，提出了这种新型的AII拮抗剂与AT1受体的结合模型。
