Porphyrins and Hepatotoxicitya

Annals of the New York Academy of Sciences, 1987
Human porphyrias are rare inborn disorders of porphyrin metabolism. Porphyria cutanea tarda is one such disorder, which may occur spontaneously after the ingestion of drugs and alcohol. This is the "constitutional" type and is associated with a deficiency of uroporphyrinogen decarboxylase in the liver.

Porphyrins. VIII. A stepwise synthesis of porphyrins

Australian Journal of Chemistry, 1964
1,2,3,4,5,6,7,8-Octanlethylporphin and a,?,1,2,3,4,5,6,7,8-decamethylporphin have been prepared by the acid-catalysed condensation of 5,5'-diformyl-3,4,3',4'-tetramethylmethanes (VI; R = H or CH3) with the corresponding dicarboxylic acid derivatives (VII), followed by oxidation.

Porphyrins, porphyrin metabolism and porphyrias. I. Update

Scandinavian Journal of Clinical and Laboratory Investigation, 2000
The biosynthesis of porphyrins is one of the most conserved parthways known, about the same sequence of reactions taking place in all species. By associating different metals, porphyrins give rise to the "pigments of life": chlorophyll, haem and cobalamin.

Porphyrin-lipoprotein association as a factor in porphyrin localization

Cancer Letters, 1986
Systemic administration of the tumor-localizing product hematoporphyrin derivative (HPD) to mice bearing the Lewis-Lung tumor leads to an initial distribution of porphyrins among plasma lipoproteins and albumin. The more hydrophobic components of HPD (including the tumor-localizing fraction) preferentially bind to plasma low density lipoprotein (LDL ...
