The CuAAC reaction was used to prepare a series of novel triazole cinnamides derivatives and a bis cinnamate. The antiproliferative and antimetastatic activities of the compounds were evaluated in vitro on a melanoma B16-F10 cell line. The most effective compound reduced the viability and influenced the metastatic behavior of melanoma cells by decreasing migration, invasion, and colony formation. Details are presented in the Article Synthesis of Novel Cinnamides and a Bis Cinnamate Bearing 1,2,3-Triazole Functionalities with Antiproliferative and Antimetastatic Activities on Melanoma Cells by Fabíola S. Santos, Juliana A. do Vale, Lucas S. Santos, Talita B. Gontijo, Graziela D. A. Lima, Leandro L. de Oliveira, Mariana Machado-Neves, Róbson R. Teixeira and Rossimiriam P. de Freitas on page 2174.

Tie-Hong Song; Yan-Jiao Gao ; Su-Yan Pang; Rui-Hua Hu; Han-Bo Li
A Fe3O4/persulfate system was used to remove bisphenol A, an emerging endocrine disruptor, in water. The effects of the pH value, reaction temperature, concentrations of Fe3O4, persulfate and bisphenol A on bisphenol A degradation were studied in detail. Free radicals scavenging experiments were performed and the intermediate products of bisphenol A degradation were identified.
