CAT and neoplasm: It also seems to be very promising to further evaluate the effects of chlorine/chloride-related compounds in CAP, due to the connection between atomic oxygen and the formation and biological significance of hypochlorite, hypochlorous acid (OCl−/HOCl) as shown by Bekeschus et al. 119, the multifaceted chemical biology of OCl−/HOCl and dichloride anion radicals (Cl2●−) as established by Wende et al. 38, the potential of HOCl to interfere with catalase activity, as shown by Krych-Madej and Gebicka120 and the generation of ●OH through interaction between HOCl and tumor cell-derived O2●− 80,121.
