  Azobenzene-diamides as Photopharmacological Ligands for Insect Ryanodine Receptor

  摘要：

  Photoresponsive ligands are powerful tool compounds for studying receptor function with spatiotemporal resolution. However, to the best of our knowledge, such a ligand is not available for the ryanodine receptor (RyR). Herein, we present a photochromic ligand (PCL) for insect RyR by decorating chlorantraniliprole (CHL) with photoswitchable azobenzene (AB). We demonstrated that one potent ligand, named ABCHL13, shows light-induced reversible trans-cis isomerization and 3.5-fold insecticidal activity decrease toward oriental armyworm (Mythimna separata) after UV-light irradiation, that is, trans-ABCH13 has higher activity than the cis-ABCH13. ABCHL13 enables optical control over intracellular Ca²⁺ release in dorsal unpaired median (DUM) neurons of M. separata and American cockroach (Periplaneta americana) and cardiac function of P. americana. Our results provide a first photopharmacological toolkit that is applicable to light-dependent regulation of RyR and heart beating.

  通过分子内噻-迈克尔策略轻松合成噻唑

  摘要：

  据报道，一种温和有效的合成取代噻唑的方法是通过一锅N-去甲硅烷基化，硫代酰化/氧硫代酰化/硫代硫酰化，然后进行噻-迈克尔环异构化。该方法通常适用于引入各种氧代和硫代官能团，包括脂族和芳族部分，尤其是在噻唑的C 2位。

  Methyl cis-deisopropyldehydroabietate was selectively nitrated at the 12-position by reaction with ‘claycop’, a montmorillonite clay impregnated with copper(II) nitrate. The 12-nitro compound was reduced to the corresponding amine and this was subjected to a combined acylation and ortho nitration. The compounds so produced were further converted into octahydro-1H-phenanthro[2,3-d]imidazoles by reductive

  通过与“ claycop”（一种浸有硝酸铜（II）的蒙脱土）反应，在12位选择性地将顺式-异异丙基脱氢松香酸甲酯硝化。将12-硝基化合物还原为相应的胺，并将其进行酰化和邻硝化的组合。通过还原环化将如此产生的化合物进一步转化为八氢-1 H-菲并[2,3- d ]咪唑。结果表明，相同的酰化-邻硝化方法可从苯胺短时间合成2-取代的苯并咪唑。

The 4-substituted benzimidazole derivatives bearing a [1,1'-biphenyl]-2-carboxamide moiety sensitized K562-resistant cells to imatinib treatment.

  最近的研究检查了通过与过氧化物酶体增殖物激活受体γ（PPARγ）配体联合治疗克服慢性粒细胞白血病（CML）患者伊马替尼耐药的可能性。吡格列酮是一种完整的PPARγ激动剂，通过逐渐消除残留的CML干细胞池，提高了患者的生存率。为了评估PPARγ激动剂的药理学特征对规避耐药性的重要性，部分PPARγ激动剂4'-（（（2-丙基-1H-苯并[d]咪唑-1-基）甲基]-[1,1]研究了替米沙坦衍生的'-联苯基] -2-羧酸和其他相关衍生物。带有[1,1'-联苯] -2-羧酰胺部分的4-取代的苯并咪唑衍生物使K562耐药细胞对伊马替尼治疗敏感。尤其是衍生物18a-f，在10μM时不会激活PPARγ超过40％的细胞，从而恢复了伊马替尼在这些细胞中的细胞毒性。细胞死亡调节特性高于吡格列酮。有趣的是，所有新化合物对非耐药性和耐药性细胞均无细胞毒性。他们仅与伊马替尼联用才发挥抗肿瘤作用。

  for several biological targets. Formation by cyclodehydration from their monoacylated counterparts was shown to be strongly dependent upon the nature of the acyl group. In the case of a dicyclohexylmethyl group, cyclization was only observed in a p-toluenesulfonic acid/toluene mixture from the symmetrical diacylated precursor. Analysis of the mechanism was begun starting from mixed diacylated derivatives

  efficient copper-catalyzed synthesis of (annelated) benzimidazoles is reported. This transformation is based on a simple and straightforward one-pot sequence involving a copper-catalyzed cross coupling between o-haloanilines and lactams/amides followed by a subsequent cyclization under acidic conditions. A variety of (annelated) benzimidazoles could be easily obtained in high yields from readily available
