• Synthesis and biological evaluation of XB-1 analogues as novel histamine H3 receptor antagonists and neuroprotective agents
  作者：Xiaofeng Bao、Yanyan Jin、Xiaolu Liu、Hong Liao、Luyong Zhang、Tao Pang

  DOI：10.1039/c3ra46392c

  日期：——

  A novel class of H3 receptor antagonists, XB-1 analogues based on benzophenone or oxydibenzene scaffolds were synthesized, and their biological activities were evaluated to determine their in vitro neuroprotective effects against Aβ25–35-induced damage in primary cortical neurons and against glutamate-induced neuronal injury in primary cerebellar granule neurons. The results indicated that all of the tested analogues displayed neuroprotective activity at 0.1 μM or 1 μM. These findings may provide new insights into the development of novel promising H3 receptor antagonists with potential neuroprotective activity.

  一类新型H3受体拮抗剂——基于苯并酮或氧二苯结构的XB-1类似物被合成，并评估了它们的生物活性，以确定它们对Aβ25–35诱导的原代皮层神经元损伤和谷氨酸诱导的原代小脑颗粒神经元损伤的体外神经保护作用。结果表明，所有测试的类似物在0.1 μM或1 μM浓度下均显示出神经保护活性。这些发现可能为开发具有潜在神经保护活性新型有前景的H3受体拮抗剂提供新思路。
• 4-Hydroxy-2'-Nitrodiphenyl Ether Analogues as Novel Tyrosinase Inhibitors

  Tyrosinase ubiquitously existing from microorganisms to animals and plants is known to be the most critical and rate limiting enzyme during melanin biosynthesis. In order to develop new tyrosinase inhibitor we have synthesized 14 diphenyl ether compounds possessing hydroxyl, bromo, and nitro groups in the structure. Among the compounds prepared, 18 and 19 have shown much stronger inhibition of tyrosinase monophenolase function than arbutin used as a positive control. Both compounds 18 and 19 possess para-hydroxyphenyl moiety in their structure, which might reinforce the importance of p-hydroxyphenyl group in the tyrosinase inhibitory process. In the DPPH radical scavenging activity test, none of the compounds even 18 and 19 showed significant antioxidant activity. The results suggest that elaborate adjustment of diphenyl ether analogues with proper substituents have potential to be developed as new skin whitening agents working on the tyrosinase function.

  从微生物到动植物中普遍存在的酪氨酸酶，在黑色素生物合成过程中被认为是最关键和限速的酶。为了开发新的酪氨酸酶抑制剂，我们合成了14种具有羟基、溴和硝基结构的双苯醚化合物。在制备的化合物中，18和19对酪氨酸酶单酚酶功能的抑制作用远强于作为阳性对照的熊果苷。化合物18和19在其结构中均具有对羟基苯基部分，这可能强化了对羟基苯基团在酪氨酸酶抑制过程中的重要性。在DPPH自由基清除活性测试中，所有化合物包括18和19均未显示出显著的抗氧化活性。这些结果表明，通过精心调整带有适当取代基的双苯醚类似物，有望开发成为针对酪氨酸酶功能的新型皮肤美白剂。
