  摘要：

  通过使用含有有机或无机紫外线过滤剂的防晒霜，可以有效地防止紫外线辐射的有害影响。当前可用的紫外线过滤剂的数量有限，并且一些允许的分子具有局限性，例如全身吸收、内分泌干扰特性、接触和光接触过敏诱导以及低光稳定性。在寻找新的有机紫外线过滤剂的过程中，我们设计并合成了一系列由 5-benzylidene 和 5-(3-phenylprop-2-en-1-ylidene)imidazolidine-2,4-dione (hydantoin) 衍生物组成的系列。测试化合物的光保护活性在甲醇溶液和聚乙二醇制剂中得到证实。最有前途的化合物具有与选定的市售紫外线过滤剂相似的紫外线防护参数值。化合物二乙基2，2'-((Z)-4-((E)-3-(4-甲氧基苯基)allylidene)-2,5-dioxoimidazolidine-1,3-diyl)diacetate (4g) 被表征为一种特别有效的 UVA 光保护剂具有

  A series of amine-alkyl derivatives of 5-arylidenehydantoin 3-21 was evaluated for their ability to improve antibiotic effectiveness in two strains of Gram-negative Enterobacter aerogenes: the reference strain (ATCC-13048) and the chloramphenicol-resistant derivative over-producing the AcrAB-TolC efflux pump (CM-64). Three antibiotics, chloramphenicol, nalidixic acid and sparfloxacin were used as markers of efflux pump activity. New compounds (5-16) were obtained within 3-4 step synthesis using Knoevenagel condensation, Mitsunobu reaction and microwave aided N-alkylation. Molecular modeling based structure-activity relationship (SAR) studies were performed. The most active compounds: (Z)-5-(4-(diethylamino) benzylidene)-3-(2-hydroxy-3-(4-(2-hydroxyethyl)piperazin-1-yl)propyl)imidazolidine-2,4-dione (14) and (Z)-5-(2,4-dimethoxybenzylidene)-3-(2-hydroxy-3-(isopropylamino)propyl)imidazolidine-2,4-dione (15) induced fourfold decrease of minimal inhibition concentration (MIC) of all tested antibiotics in the strain CM-64 overexpressing the AcrAB-TolC pump.

  Background: Many tyrosinase inhibitors find application in cosmetics and pharmaceutical products for the prevention of the overproduction of melanin in the epidermis. A series of 5-(substituted benzylidene) hydantoin derivatives 2a-2k were prepared, and their inhibitory activities toward tyrosinase and melanin formation were evaluated.Methods: The structures of the compounds were established using H-1 and C-13 NMR spectroscopy and mass spectral analyses. All the synthesized compounds were evaluated for their mushroom tyrosinase inhibition activity.Results: The best results were obtained for compound 2e which possessed hydroxyl group at R-2 and methoxy group at R-3, respectively. We predicted the tertiary structure of tyrosinase, simulated its docking with compound 2e and confirmed that this compound interacts strongly with mushroom tyrosinase residues as a competitive tyrosinase inhibitor. In addition, we found that 2e inhibited melanin production and tyrosinase activity in B16 cells.Conclusions: Compound 2e could be considered as a promising candidate for preclinical drug development in skin hyperpigmentation applications.General significance: This study will enhance understanding of the mechanism of tyrosinase inhibition and will contribute to the development of effective drugs for use hyperpigmentation.
