Two novel and unusal porphyrins have been isolated from the pool of porphyrin metabolites in cultures of Pseudomonas. They correspond to substitution of a meso proton in uroporphyrin by a nitro group or a chlorine atom. The purified compounds have been characterized by 1H-nmr, mass spectrometry, and visible spectroscopy to establish their structure.
