Porphyrin derivatives accumulate selectively in cancer cells and are can be used as carriers of drugs. Until now, the substituents that bind to porphyrins (mainly at the meso-position) have been actively investigated, but the effect of the functional ...

Bis-Porphyrin Racks with Space-Separated Co-Planar Porphyrin Rings
A porphyrin appended norbornenyl building block 8 has been isolated and coupled, using a 1,3-dipolar ACE reaction, to yield bis-porphyrin compounds in which the porphyrin moietes are angled upward relative to the norbornane backbone.

The biosynthesis of porphyrins
This article is intended as a summary of some of the work which has been done, over the past ten years, on the biosynthesis of porphyrins. The treatment accorded to this subject should not be considered to be that of an exhaustive review article. It will consider only those papers which, in the author’s opinion, are most pertinent to the particular ...

One‐Step Curcumin‐Mediated Multiphoton Lithography for Bioactive 3D Scaffolds
Curcumin‐mediated multiphoton lithography enables one‐step fabrication of highly architected complex gelatin methacryloyl scaffolds by exploiting curcumin as a multifunctional bioactive photoinitiator. The resulting 3D structures support mesenchymal stem cell adhesion, proliferation, and migration, while exhibiting dual antibacterial activity through ...

An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...
