  四唑酰肼类化合物是JumonjiC域含组蛋白去甲基化酶KDM4A的选择性片段样抑制剂

  摘要：

  含有JumonjiC域的组蛋白去甲基化酶2A（JMJD2A，KDM4A）是基因表达的表观遗传调控中的关键角色。以前的出版物表明，升高和降低的酶水平均与某些类型的癌症有关，因此，KDM4A在肿瘤发生中的明确作用仍然难以捉摸。为了鉴定具有良好理化性质的新型分子起点来研究KDM4A的生理作用，我们通过使用两次独立的试验筛选了许多带有铁螯合部分的分子。通过这种方法，我们能够鉴定出2-（1 H-四唑-5-基）乙酰肼为新颖的类似片段的铅结构，相对分子质量低（M r = 142 Da），复杂度低，并且IC 5046.6μ值米在甲醛脱氢酶（FDH） -偶联测定法和2.4μ米在基于抗体的测定法。尽管它的体积很小，但是对于该化合物而言，可以证明它对另外两种脱甲基酶的相对选择性。这是四唑基团作为JMJD脱甲基酶中的战斗部的第一个例子。

  The Knoevenagel condensation of arylacetonitriles with ethyl 4,6-dichloro-3-formyl-1H-indole-2-carboxylate (2), followed by hydrolysis, provides a convenient entry into a series of analogs of MDL 105,519, 1, a selective glycine site N-methyl-d-aspartate (NMDA) receptor antagonist. Surprisingly, the hydrolysis of the indole arylpropenenitriles terminates at the formation of the corresponding carboxamide

Also with these substrates, an interesting ring-opening/S-alkylation process was observed when the reductive alkylation were performed at -78 ˚C to give 1-alkylsulfanyl-1,3,4-trienes.

• Basic enemies of photochromism: irreversible transformation of fluorinated diarylethenes to polyenic enamines and enols
  作者：Dmytro Sysoiev、Thomas Huhn

  DOI：10.1039/d0pp00292e

  日期：2020.11

  Non-photochemical degradation of perfluorinated photochromic diarylethenes (DAE) under Knoevenagel, Sonogashira or Wittig conditions was discovered. This base promoted formation of strongly colored non-photochromic byproducts has an impact in the field of molecular electronics due to the basic conditions often employed during deacylation and desilylation of the protected thiol anchoring groups of functionalized DAE. The products were identified as seven-membered ring systems of the bicyclo[5.3.0]deca-1,7-diene type. Their formation was rationalized by a tentative two-step reaction mechanism.
