Biopyrrin pigments, which result from the degradation of heme in biological settings, feature three or two pyrrole rings and characteristic pyrrolin-2-one termini. These scaffolds serve as redox-active ligands and electron reservoirs in coordination compounds. Tripyrrin-1,14-dione coordinates divalent transition metals as a dianionic ligand hosting a delocalized radical. Herein, we report the synthesis and characterization of palladium(II) and platinum(II) tripyrrindione complexes featuring a primary amine (i.e., aniline, tert-butylamine, 1,2-ethylenediamine) at the fourth coordination site within square planar geometries. Interligand hydrogen-bonding interactions are observed between the coordinated amine and the carbonyl groups on the tripyrrindione scaffold. Notably, 1,2-ethylenediamine is employed to link two Pt(II) tripyrrindione complexes. As revealed by optical absorption and electron paramagnetic resonance (EPR) spectroscopy, all resulting complexes present ligand-based radicals that are stable at room temperature and when exposed to air. Spin pairing through multicenter interactions leads to [Formula: see text]-dimerization of the tripyrrindione radicals and a decrease in the EPR signal at low temperatures. Electrochemical measurements indicate that the ligand system undergoes quasi-reversible one-electron oxidation and reduction, thus confirming the ability of tripyrrindione to form square planar complexes in three different redox states.

The synthesis and characterization of a novel hexacoordinated compound as a product of the reaction between chlorodimethylesterprotoprphyrin–Fe(III) 1 and 2–methylpiridine (2–CH3Py) was performed. The [bis(o–methylpyridino)(dimethylesterprotoporphyrinato)Fe(III)] chloride 2 is a compound of the family of the pinch–porphyrins, a model of peroxidase enzymes. We analyzed 2 using UV-Vis, 1H NMR, and EPR spectroscopies, as well as kinetic quantifications of its peroxidase activity and computational analysis, to evaluate the presence of the pinch-ligand coordinated to 1 in a series of pinch-ironprotoporphyrin complexes, as previously reported. Our investigation revealed that the oxidant activity of Compound I derived from peroxidase activity determination of 1 and 2, respectively, is better controlled when a heterohydrocarbonated chain is attached to the pyridyl groups that coordinate axially to 1; an effect evidenced by a decrease of the activation energy value associated with Compound 0 formation during the reaction performed by pinch–porphyrin, with the picdien axial ligand and hydrogen peroxide. When correlating the contribution of [Formula: see text]3/2 in the quantum mixed-spin state (qms), [Formula: see text]3/2, [Formula: see text]5/2, of iron(III)-based complexes with their peroxidase activity, we found that when the qms [Formula: see text]3/2, [Formula: see text]5/2, of iron(III) had 80% character [Formula: see text]3/2, the peroxide activity increased significantly. This could be a fundamental trait that could affect the peroxidase activity owing to the distortion of the iron geometry associated with its coordination number when [Formula: see text]methylpyridine is used as an axial ligand.

[Formula: see text]-Unsubstituted 5-monoazaporphyrin (MAP) copper complex 10,15,20-tritolyl-5-monoazaporphyrinato copper(II) (Cu-MAP) 3 was synthesized by reaction of 1,19-dibromotetrapyrrane with NaN3-CuI in good yield. Following successive reactions of demetallation, metallation and bromination, the important precursor 3,7-dibromo-10,15,20-tritolyl-5-monoazaporphyrinato nickel(II) ([Formula: see text],[Formula: see text]′-dibromo Ni-MAP) 6was prepared smoothly. Suzuki-Miyaura coupling reactions of 6 with three organic borides resulted in the “earring” Ni-MAP 7, pyrrole bridged Ni-MAP oligomers 8 and 9, and benzene bridged Ni-MAP oligomers 10 and 11, respectively. The structures of MAPs 3, 6, 7, 8, 10 and 11 were confirmed by X-ray diffraction analysis. Optical and electrochemical studies were performed to understand their electronic properties.

Porphyrin PSs, possessing high photosensitivity and stability, have widespread use in phototherapy. Furthermore, the use of Q[n]s as a carrier for PSs has contributed to enhancing the efficacy of photodynamic therapy. In the present study, we synthesized 2TMeQ[6]-TPPPA self-assembled compounds, comprising TMeQ[6] and 5, 10, 15, 20-tetra (4-pyridyl, N-propyl ammonia) porphyrin derivatives (TPPPA) (in a 2:1 ratio), to investigate their capacity to generate reactive oxygen species (ROS) and their effect of self-assembly with TMeQ[6] on the efficacy of human neuroblastoma cell line (SH-SY5Y). Our results demonstrate that both TPPPA and 2TMeQ[6]-TPPPA generate substantial amounts of ROS under laser irradiation, which is directly proportional to the duration of illumination. Furthermore, both compounds exhibited significant cytotoxic effects on SH-SY5Y cells, as demonstrated by the MTT assay. Western blotting revealed a marked increase in the expression of Cleaved caspase-3, Cleaved caspase-9, and Bax, and a decrease in the expression of Bcl-2, confirming that caspase-dependent apoptosis is involved in SH-SY5Y cell death induced by TPPPA photodynamic therapy. ROS overproduction plays a crucial role in this process, and NAC preconditioning was shown to reduce cytotoxicity and inhibit pro-apoptotic protein molecules. However, 2TMeQ[6]-TPPPA was less effective than TPPPA in terms of ROS production capacity and toxicity to SH-SY5Y cells after self-assembling with TMeQ[6]. In conclusion, our study explored that TPPPA can induce ROS overproduction leading to apoptosis, and its mediated photodynamic therapy is a highly effective treatment option for SH-SY5Y cells. After self-assembling with TMeQ[6], TPPPA retains its apoptotic pathway-inducing characteristics and acts as a carrier, but this is not conducive to the photodynamic enhancement of TPPPA.
