CNP exerts a catalase activity that differs between tumour and normal cells.


They have been reported to enhance the antitumor activity of doxorubicin, probably related to reactive oxygen species (ROS) generation, and oxidative damage after co-incubation. In contrast CNP do not cause damage and even protect human dermal fibroblast (Mol Cancer Ther. 2014; 13:1740). However, this activity is insufficiently studied in different cellular lines and with different cytotoxic agents.
