Many studies have established a role for oxidative stress and mitochondrial dysfunction as an important mechanism in the pathogenesis of neuronal disorders. Metalloporphyrins are a class of catalytic antioxidants that are capable of detoxifying a wide range of reactive oxygen species. The AEOL112 series of glyoxylate metalloporphyrins were designed with increased lipid solubility for better ora...

The Front Cover shows an engaging platform for electrochemical sensor development: Metalloporphyrins. Although the last years have been times of numerous technological transitions, porphyrins and currently are critical building blocks in development micro-/nanosensors. In recent years, not only small molecules detected quantified, but it is now also possible to measure relevant macromolecules w...

Through the use of the tetratopic ligand 1,2,4,5-tetrakis(4-carboxyphenyl)benzene as a key building block, a permanently microporous metal-organic framework with Lewis acidic (porphyrin)Zn struts, ZnPO-MOF, can be made in high yields. ZnPO-MOF can efficiently catalyze acyl-transfer reactions primarily by preconcentrating the substrates within its pores, in stark contrast to analogous supramolec...

Studies on the physiological role of heme oxygenase (HO) require an inhibitor that will selectively inhibit HO activity without inhibiting the activity of either nitric oxide synthase (NOS) or soluble guanylyl cyclase (sGC). The objective of this study was to test a series of metalloporphyrins that have previously been shown to inhibit HO activity, for their ability to inhibit HO without inhibi...

Molecular assemblies of metalloporphyrins trans-dichloro(5,10,15,20-tetra-p-tolylporphyrinato)tin(IV) (SnCl2TPPMe) and trans-dihydroxo(5,10,15,20-tetra-p-tolylporphyrinato)tin(IV) (Sn(OH)2TPPMe), which have two trans axial ligands, as well 5,10,15,20-tetrakis(4-methoxyphenyl)-21H,23H-porphine iron(III) chloride (FeClTPPOMe) and 5,10,15,20-tetraphenyl-21H,23H-porphine manganese(III) chloride (Mn...

Varying the solution growth conditions of cooperative binary ionic solids composed of anionic and cationic metalloporphyrins produces a series of families of self-assembled structures that efficiently and durably photosensitize the evolution of hydrogen.
