Surgical inflammation: a pathophysiological rainbow
Journal of Translational Medicine, 2009 Tetrapyrrole molecules are distributed in virtually all living organisms on Earth. In mammals, tetrapyrrole end products are closely linked to oxygen metabolism. Since increasingly complex trophic functional systems for using oxygen are considered in the

Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres
Chemistry – A European Journal, EarlyView.We expand the scope of Pd12L24 nanospheres equipped with porphyrins. Focusing on the porphyrin metallation state, synthetic strategies for porphyrin building block (BB)compounds are developed. The compounds are evaluated against nanosphere self‐assembly conditions.

Prevention of poxvirus infection by tetrapyrroles [PDF]
BMC Infectious Diseases, 2003 Prevention of poxvirus infection is a topic of great current interest. We report inhibition of vaccinia virus in cell culture by porphyrins and phthalocyanines. Most previous work on the inhibition of viruses with tetrapyrroles has involved photodynamic mechanisms.

Natural Product Gene Clusters in the Filamentous Nostocales Cyanobacterium HT-58-2
Life, 2021 Cyanobacteria are known as rich repositories of natural products. One cyanobacterial-microbial consortium (isolate HT-58-2) is known to produce two fundamentally new classes of natural products: the tetrapyrrole pigments tolyporphins A–R, and the ...
