Wen Luo et al.
Journal of enzyme inhibition and medicinal chemistry, 26(5), 706-711 (2011-01-22)
A novel series of N,N'-bis-methylenedioxybenzyl-alkylenediamines 5a-5g have been designed, synthesized and evaluated as bivalent anti-Alzheimer's disease ligands. The enzyme inhibition assay results indicated that compounds 5e-5g inhibit both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) in the micromolar range (IC(50), 2.76-4.24 µM

Water research, 47(2), 579-587 (2012-11-22)
The transformation of two benzophenone UV filters (Oxybenzone and Dioxybenzone) was examined over the pH range 6-11 in the presence of excess aqueous chlorine. Under these conditions, both UV filters were rapidly transformed by aqueous chlorine just above circumneutral pH
Vaughn F Sherwood et al.
Cutaneous and ocular toxicology, 31(4), 273-279 (2012-01-20)
Sunscreens are widely utilized due to the adverse effects of ultraviolet (UV) radiation on human health. The safety of their active ingredients as well as that of any modified versions generated during use is thus of concern. Chlorine is used

Analytica chimica acta, 638(1), 36-44 (2009-03-21)
A sensitive procedure for the determination of three UV filters: ethylhexyl salicylate (EHS), 3,3,5-trimethylcyclohexyl salicylate (Homosalate, HMS), 2-hydroxy-4-methoxybenzophenone (BP-3) and two related hydroxylated benzophenones (2,4-dihydroxybenzophenone, BP-1 and 2,2'-dihydroxy-4-methoxybenzophenone, BP-8) in water samples is presented. Analytes were first concentrated on the

Anticancer research, 33(6), 2535-2540 (2013-06-12)
Sunscreen compounds with added benefit of skin cancer prevention have both public and commercial interests. Our earlier study using the Epstein-Barr virus early antigen in vitro assay reported on skin cancer chemoprevention potential of benzophenone sunscreens. We now report the
