Published: May 2023

Five topics pertaining to the unique chemistry of metalloporphyrins as observed in multi-metal complex systems are introduced. The topics include the following: (i) the unique chromatographic separation of cyclic porphyrins on modified silica gel; (ii) room temperature phosphorescence from the zinc porphyrin part in a zinc porphyrin/rhenium complex hetero dyad; (iii) the substituent effect, in the preparation of a readily soluble special-pair-type zinc porphyrin dimer/rhenium complex having efficient photocatalytic CO reduction ability; (iv) assessment of the excited triplet state of a special-pair-type zinc porphyrin dimer in macrocyclic multiporphyrin rings; and (v) solvation/desolvation indicators based on exclusive transformation between the head-head type and head-tail type of supramolecular co-ordination polymers composed of bis(zinc porphyrin)s.

Ferroptosis combined with photodynamic therapy (PDT) has emerged as a powerful approach to induce cancer cell death by producing and accumulating lethal reactive oxygen species (ROS) in the tumor microenvironment (TME). Despite its efficacy and safety, challenges persist in delivering multiple drugs to the tumor site for enhanced antitumor efficacy and improved tissue targeting. Hence, we designed a method of inducing ferroptosis through laser-mediated and human homologation-specific efficient activation, which is also a ferroptosis therapy with higher safety through ROS-mediated.

Article Synopsis
  • Ochratoxin A (OTA) is a harmful mycotoxin found in food that poses health risks, making its detection in cereal-based foods crucial.
  • A novel sensor was developed using zinc-tetrakis (4-carboxyphenyl) porphyrin (Zn-TCPP) nanorods and BiS@Au nanoflowers, which enhanced luminescence signals and allowed for the ultra-sensitive detection of OTA in various food samples.
  • This innovative approach not only effectively detects OTA at very low concentrations (as low as 0.13 pg/mL) but also offers a promising research avenue for analyzing other mycotoxins and advancing the study of metal-organic frameworks.

Article Synopsis
  • The study focuses on creating enhanced host-guest complexes using a gold nanocluster and a zinc porphyrin nanoring, which is important in supramolecular chemistry.
  • Strong binding was observed between the gold nanocluster and the six-unit zinc porphyrin nanoring, confirmed through various analytical techniques including UV/Vis absorption and mass spectrometry.
  • The resulting complex not only stabilizes the gold nanocluster but also shows improved activity and selectivity in photochemical reactions, specifically converting carbon monoxide and generating singlet oxygen.

[2]Rotaxanes offer unique opportunities for studying and modulating charge separation and energy transfer, because the mechanical bond allows the robust, yet spatially dynamic tethering of photoactive groups. In this work, we synthesized [2]rotaxane triads comprising a central (aza)[10]CPP⊃C bis-adduct complex and two zinc porphyrin stoppers to address how the movable nanohoop affects light-induced charge separation and energy transfer between the rotaxane subcomponents. We found that neither the parent nanohoop [10]CPP nor its electron-deficient analogue aza[10]CPP actively participate in charge separation.

Vascular endothelial injury is closely related to the progression of various cardio-cerebrovascular diseases. Whether Human Urinary Kallidinogenase (HUK) has a protective effect on endothelial injury remains unclear. This study established an in vivo model of rat common carotid artery intima injury and an in vitro model of human umbilical vein endothelial cell (HUVECs) injury induced by hydrogen peroxide (HO).
