Manganese superoxide dismutase, MnSOD and its mimics.
Miriyala S, Spasojevic I, Tovmasyan A, Salvemini D, Vujaskovic Z, St Clair D, Batinic-Haberle I. Miriyala S, et al. Biochim Biophys Acta. 2012 May;1822(5):794-814. doi: 10.1016/j.bbadis.2011.12.002. Epub 2011 Dec 9. Biochim Biophys Acta. 2012. PMID: 22198225 Free PMC article. Review.
Methoxy-derivatization of alkyl chains increases the in vivo efficacy of cationic Mn porphyrins. Synthesis, characterization, SOD-like activity, and SOD-deficient E. coli study of meta Mn(III) N-methoxyalkylpyridylporphyrins.
Tovmasyan AG, Rajic Z, Spasojevic I, Reboucas JS, Chen X, Salvemini D, Sheng H, Warner DS, Benov L, Batinic-Haberle I. Tovmasyan AG, et al. Dalton Trans. 2011 Apr 28;40(16):4111-21. doi: 10.1039/c0dt01321h. Epub 2011 Mar 8. Dalton Trans. 2011. PMID: 21384047 Free PMC article.
The SOD-like activities and metal-centered reduction potentials for the Mn(III)P/Mn(II)P redox couple were similar-to-identical to those of N-alkylpyridyl analogs: log k(cat) = 6.78, and E(1/2) = +68 mV vs. NHE (MnTMOHex-3-PyP(5+)), and log k(cat) = 6.72, and E(1/2) …

Design of Mn porphyrins for treating oxidative stress injuries and their redox-based regulation of cellular transcriptional activities.
Batinic-Haberle I, Spasojevic I, Tse HM, Tovmasyan A, Rajic Z, St Clair DK, Vujaskovic Z, Dewhirst MW, Piganelli JD. Batinic-Haberle I, et al. Amino Acids. 2012 Jan;42(1):95-113. doi: 10.1007/s00726-010-0603-6. Epub 2010 May 16. Amino Acids. 2012. PMID: 20473774 Free PMC article. Review.
We have reported on the inhibition of major transcription factors HIF-1alpha, AP-1, SP-1, and NF-kappaB by Mn porphyrins. While the prevailing mechanistic view of the suppression of transcription factors activation is via antioxidative action (presumably in cytosol) …
