 Use of ecamsule


Ecamsule is a broad-spectrum UVA filter that can be used in sunscreen product. Ecamsule reduces biological damage caused by solar radiation such as pyrimidine dimer formation, p53 protein accumula-tion, or collagenase 2 expression. Ecamsule has the potential for the research of polymorphous light eruption (PMLE) [1] [2].

Ecamsule has the potential for the research of polymorphous light eruption (PMLE) [1] [2].
Related Catalog
In Vitro Ecamsule is a broad-spectrum UVA-absorber with maximum absorbance at 344 nm[1]. Wild-type Fibs E6/E7 cells are more sensitive towards Ecamsule (200-1600 μM) treatment[1]. . Ecamsule counteractes UV and AAPH induced ROS-formation[1]. .The effects are dose-dependent, reaching a maxi-mum ROS reduction by 25.7% at the highest tested concentration of 1600 μM in the UV-setting. With the same concentration of Ecamsule, oxidative stress that had been trigged by AAPH is reduced by 10.8% and basal levels are attenuated by 16.9%[1]. . Ecamsule increases the viability at the highest applied concentration of 1600 μM in the AAPH-treated cells[1].
