  Modification of cap group in δ-lactam-based histone deacetylase (HDAC) inhibitors

  摘要：

  Novel delta-lactam-based HDAC inhibitors which have various substituted benzyl, bi-aromatic cap groups were prepared using ring closure metathesis reaction, and evaluated their HDAC inhibitory activities and anti-proliferative effects. Among prepared analogues, 11m and 11o have very strong HDAC enzymatic inhibition and showed the most potent growth inhibitory activity to five human tumor cell lines including PC-3, ACHN, NUGC-3, HCT-15, and MBA-MB-231 tumor cell lines. Compounds 11m and 11o also showed good tumor growth inhibition of MDA-MB-231 cells in in vivo xenograft model. Structure-activity relationship study using docking model explained the significance of hydrophobic aromatic cap groups for their in vitro activities. (C) 2007 Elsevier Ltd. All rights reserved.

  氟乙烯对α-氟化α，β-不饱和内酰胺和内酯的闭环复分解

  摘要：

  使用 Grubbs II 或 Hoveyda 催化剂的闭环烯烃复分解反应 (RCM) 已应用于一系列 N-烯基-N-苄基-α-氟丙烯酰胺。α-氟代-α,β-不饱和γ-或δ-内酰胺结合了氟化双键，收率中等至良好，这取决于苄基环上取代基的性质。在类似条件下未形成相应的七元和八元内酰胺。当 N-苄基被 N-甲苯磺酰基取代时，相应的 ϵ-内酰胺也以 38% 的产率形成。当使用 N-(2-氟烯丙基) 衍生物代替氟丙烯酰基衍生物时，以低产率获得六元、七元和八元 N-杂环。该方法还用于从脯氨醇合成吡咯里西啶和吲哚里西啶生物碱的氟化α，β-不饱和类似物，并且还从市售的 2-乙烯基苯胺中分三步合成 N-苄基-3-氟喹诺酮，总产率为 44%。3-氟香豆素和3-氟色烯由邻乙烯基苯酚制备，3-氟-苯并氧杂则由邻烯丙基苯酚制备。

  Herein is described an efficient and chemoselective method for the synthesis of diversely substituted secondary amines in yields up to 98 %. Direct mono-N-alkylation of primary benzylamines and anilines with a wide range of alkyl halides is promoted by a cesium base in the absence of any additive or catalyst. The basicity and solubility of cesium carbonate in anhydrous N,N-dimethylformamide not only

  Herein, we report a nickel-catalyzed reductive cross-coupling reaction of easily accessible 3-butenyl carbamoyl chloride with primary alkyl iodide to access the chiral α-alkylated pyrrolidinone with broad substrate scope and high ee. The current art of synthesis still remains challenging on the enantioselective α-monoalkylation of pyrrolidinones. The newly designed chiral 8-quinoline imidazoline ligand

  在此，我们报告了镍催化的 3-丁烯基氨基甲酰氯与伯烷基碘的还原交叉偶联反应，以获得具有广泛底物范围和高 ee 的手性 α-烷基化吡咯烷酮。目前的合成技术对吡咯烷酮的对映选择性 α-单烷基化仍然具有挑战性。新设计的手性 8-喹啉咪唑啉配体（Quinim）对于保持反应性和对映选择性至关重要，以确保单取代烯烃的还原环化，从而前所未有地合成手性非芳香杂环。

  corresponding ϵ-lactam was also formed in 38 % yield. When N-(2-fluoroallyl) derivatives were used instead of fluoroacryloyl derivatives, six-, seven-, and eight-membered N-heterocycles were obtained in low yields. This method was also used to synthesize fluorinated α,β-unsaturated analogues of pyrrolizidine and indolizidine alkaloids from prolinol, and also to synthesize N-benzyl-3-fluoroquinolone in

  transcription factor 3 (RUNX3) are regulated by histone deacetylase (HDAC). HDAC inhibition alters epigenetic and posttranslational stability of RUNX3, leading to tumor suppression. However, HDAC inhibitors can nonselectively alter global gene expression through chromatin remodeling. Thus, lactam‐based HDAC inhibitors were screened to identify potent protein stabilizers that maintain RUNX3 stability by acetylation

  肿瘤抑制子相关转录因子3（RUNX3）的表达和稳定性受组蛋白脱乙酰基酶（HDAC）调节。HDAC抑制会改变RUNX3的表观遗传和翻译后稳定性，从而导致肿瘤抑制。但是，HDAC抑制剂可以通过染色质重塑非选择性地改变全局基因的表达。因此，筛选了基于内酰胺的HDAC抑制剂以鉴定有效的蛋白质稳定剂，该稳定剂可通过乙酰化保持RUNX3的稳定性。通过基于细胞的RUNX激活和HDAC抑制测定法确定了111种基于内酰胺的类似物的RUNX活性和HDAC抑制作用。3- [1-（4-溴苄基）-2-氧代-2,5-二氢-1 H-吡咯-3-基] -N-羟基丙酰胺（11-8）可显着提高RUNX3的乙酰化和稳定性，并具有相对较低的RUNX3 mRNA表达和HDAC抑制活性。在MKN28异种移植模型中，该化合物显示出显着的抗肿瘤作用，比SAHA强。因此，我们提出了一种新的策略，其中HDAC抑制剂用作选择性靶向RUNX3的表

  The first ring-closing olefin metatheses of alkenyl alpha-fluoracrylamides or acrylates incorporating a fluorinated double bond are reported. Several N-benzyl-N-alkenyl-alpha-fluoroacrylamides were cyclized in the presence of 2 mol % of Grubbs II catalyst at room temperature to form an unsaturated gamma-lactam, and at 80degreesC to form the corresponding delta-lactams bearing a fluoro vinyl moiety. At elevated temperature, cyclization of an N-methallyl 2-fluoroacrylamide to form a fluorinated, tetrasubstituted double bond was achieved. Similarly, 3-fluorocoumarin was prepared from (2-vinylphenyl)-alpha-fluoroacrylate. (C) 2003 Elsevier Ltd. All rights reserved.
