  Acylhydrazones as Widely Tunable Photoswitches

  摘要：

  Molecular photoswitches have attracted much attention in biological and materials contexts. Despite the fact that existing classes of these highly interesting functional molecules have been heavily investigated and optimized, distinct obstacles and inherent limitations remain. Considerable synthetic efforts and complex structure property relationships render the development and exploitation of new photoswitch families difficult. Here, we focus our attention on acylhydrazones: a novel, yet underexploited class of photochromic molecules based on the imine structural motif. We optimized the synthesis of these potent photoswitches and prepared a library of over 40 compounds, bearing different substituents in all four crucial positions of the backbone fragment, and conducted a systematic study of their photochromic properties as a function of structural variation. This modular family of organic photoswitches offers a unique combination of properties and the compounds are easily prepared on large scales within hours, through an atom-economic synthesis, from commercially available starting materials. During our thorough spectroscopic investigations, we identified photoswitches covering a wide range of thermal half-lives of their (Z)-isomers, from short-lived T-type to thermally stable P-type derivatives. By proper substitution, excellent band separation between the absorbance maxima of (E)- and (Z)-isomers in the UV or visible region could be achieved. Our library furthermore includes notable examples of rare negative photochromic systems, and we show that acylhydrazones are highly fatigue resistant and exhibit good quantum yields.

  involved in regulation of serum uric acid, xanthine oxidase (XO) is the best pharmacological target to control the levels of serum uric acid as it catalyzes the final steps in uric acid production. In the current study, a systemic search for the inhibitors of xanthine oxidase, starting from synthesis to in vitro screening and leading to in vivo studies is presented.

  生活方式和饮食习惯的改变导致全球高尿酸血症的患病率增加。高尿酸血症的作用不再局限于痛风，而在CVD，高血压，代谢综合征和关节炎的进展中起着核心作用。在涉及调节血清尿酸的不同因素中，黄嘌呤氧化酶（XO）是控制血清尿酸水平的最佳药理学靶标，因为它催化了尿酸生产的最终步骤。在当前的研究中，从合成到体外筛选，再到体内研究，对黄嘌呤氧化酶抑制剂进行了系统的研究。通过用取代的芳族醛处理烟碱/异烟碱酰肼来合成苄叉烟碱/异烟碱酰肼（1-54），并通过EI-MS和1H NMR进行表征。还进行了元素分析。首先使用体外光谱XO抑制试验筛选所有合成化合物的黄嘌呤氧化酶抑制活性。与标准药物别嘌呤醇IC50 = 2.00±0.01μM相比，发现其中22种衍生物的IC50值为0.96至330.4μM。对五种活性最高的化合物（8、35、36、39和45）进行了动力学研究，其IC50值在0.96至54.8μM之间，具有抑制
