Abstract

Although its first military use in Ypres was 100 years ago, no causal therapy for sulfur mustard (SM) intoxications exists so far. To improve the therapeutic options for the treatment of SM intoxications, we developed a co-culture of keratinocytes (HaCaT cells) and immunocompetent cells (THP-1 cells) to identify potential substances for further research. Here, we report on the influence of necrosulfonamide (NSA) on the course of a SM intoxication in vitro. The cells were challenged with 100, 200 and 300 mu M SM and after 1 h treated with NSA (1, 5, 10 mu M). NSA was chosen for its known ability to inhibit necroptosis, a specialized pathway of programmed necrosis. However, in our settings NSA showed only mild effects on necrotic cell death after SM intoxication, whereas it had an immense ability to prevent apoptosis. Furthermore, NSA was able to reduce the production of interleukin-6 and interleukin-8 at certain concentrations. Our data highlight NSA as a candidate compound to address cell death and inflammation in SM exposure.
