  Discovery, Synthetic Methodology, and Biological Evaluation for Antiphotoaging Activity of Bicyclic[1,2,3]triazoles: In Vitro and in Vivo Studies

  摘要：

  Novel bicyclic[1,2,3]triazoles (4, 7, 11, 15) have been synthesized using a one-pot metal free strategy with high structural diversity as photoprotective agents, and their effect on UVA-induced senescence in human dermal fibroblast cells (FB) and the associated mechanism are delineated. lid plus UVA can induce a decrease in reactive oxygen species (ROS) production and senescence-associated beta-galactosiclase (SA-beta-gal) activity but an increase in adenosine triphosphate (ATP) synthesis and mitochondrial membrane potential (Delta psi(mt)). The mRNA levels of six senescence-associated genes, matrix metalloproteinase-1 (MMP-1), was decreased, while elastin, procollagen I type I, fibronectin, COL1 alpha 1, and tissue inhibitor of metalloproteinase-1 (TIMP-1) were increased. lid plus UVA also decreased MMP-1 and increased TIMP-1 protein levels. Additionally, the thickness of the minim dorsal skin and epidermis, by UVA, was decreased by topical lid treatment. Our results indicate that bicyclic[1,2,3]triazoles protect UVA-induced senescence-like characteristics in FB cells, which may provide potential prevention against photoaging.

  hydrogenation reaction of (1,2,3)triaz olo(1,5-a)pyridines with Pd/C/Zn or Pd(OH) 2/C/Zn in water, ethanol or water/ethanol mixture ha s been explored. 4,5,6,7-Tetrahydro- triazolopyridines were obtained in good to medium yields. In addition, under the same conditions 2-substituted pyridines were also formed as a resul t of intermediate pyridylcarbene formation, by triazole ring opening and loss of nitrogen

  (1,2,3)triaz olo(1,5-a)吡啶与Pd/C/Zn或Pd(OH) 2/C/Zn在水、乙醇或水/乙醇混合物中的转移加氢反应已有探索。4,5,6,7-四氢-三唑并吡啶以良好至中等产率获得。此外，在相同条件下，由于三唑开环和氮损失，中间体吡啶卡宾形成的结果也形成了 2-取代的吡啶。
