《Synthesis of 1,2,3-triazole benzophenone derivatives and evaluation of in vitro sun protection, antioxidant properties, and antiproliferative activity on HT-144 melanoma cells》 was written by Dias, Maria C. F.; de Sousa, Bianca L.; Ionta, Marisa; Teixeira, Robson R.; Goulart, Thiago Q.; Ferreira-Silva, Guilherme A.; Pilau, Eduardo J.; dos Santos, Marcelo H.. Product Details of 622-95-7This research focused ontriazole benzophenone derivative antioxidant antitumor photoprotective human. The article conveys some information:
Two series of 1,2,3-triazole-benzophenone derivatives I [R = R1 = Ph, 3-MeC6H4, 4-ClC6H4, etc.] and II [R2 = Ph, 2-pyridyl, 4-BrC6H4, etc.] were synthesized and their antioxidant, anticancer and photoprotective effects evaluated. For the compounds synthesis, 4,4′-dihydroxybenzophenone and 2,4-dihydroxybenzophenone were propargylated and afforded alkynes, bis(4-(prop-2-yn 1-yloxy))benzophenone and (2-hydroxy-4-(prop-2-yn-1-yloxy))benzophenone, resp. The copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction between the alkynes and several benzyl azides gave the compounds I and II with yields ranging from 35 to 95%. Compounds I and II at the concentration of 0.2μg mL-1 (a no-cytotoxic concentration) exhibited a solar protection factor (SPF) comparable to pos. control benzophonen-3 (BP-3). Concerning their antioxidant and cytotoxic effects, the derivatives from 2,4-dihydroxybenzophenone showed high in vitro antioxidant effects as well as cytotoxicity against A549 (lung carcinoma), MCF-7 (breast carcinoma) and HT-144 (metastatic melanoma) cell lines, without significant cytotoxicity to a non-cancerous cell line. Derivatives II [R2 = Ph, 4-MeC6H4, 2,4-F2C6H3] induced cell death and cell cycle arrest at G1/S in HT-144 melanoma cells. In addition to this study using 1-(Bromomethyl)-4-chlorobenzene, there are many other studies that have used 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Product Details of 622-95-7) was used in this study.
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) undergoes carbonylation in the presence of dimer of chloro(1,5-cyclooctadiene)rhodium(I) to yield the corresponding phenylacetic acid.Product Details of 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
