As mentioned above, Cl[sub]2 toxicity is mainly caused by oxidative stress to tissues; thus, antioxidants including dimethylthiourea,[18] compound AEOL 10150 (a metalloporphyrin catalytic antioxidant),[35] N-acetyl cysteine,[36] aerosolized ascorbate, and deferoxamine [16] have been shown to alleviate Cl[sub]2-induced injury in animal models of different species.
This higher complexity of tetraazamacrocyclic ligands, specifically porphyrin ligands or porphyrin derivatives, such as chlorins, has several causal factors, one of the most relevant being the significant flexibility of the porphyrin ring, which can generate a series of spatial conformations Which have been studied in different metalloporphyrins, which has been studied in both metalloporphyrin complexes alone and in heme groups in several hemoproteins [24-28].
