Porphyrins and Hepatotoxicitya
Annals of the New York Academy of Sciences, 1987Human 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.

The Biochemistry of the Porphyrins
Clinics in Haematology, 1980SUMMARY This chapter has reviewed the means by which haem and porphyrins are synthesized and degraded, and some of the biological roles of these compounds. It has also dealt with systems of control of the biosynthetic pathway, and the importance of these control mechanisms in cellular homeostasis.

Porphyrins, porphyrin metabolism and porphyrias. I. Update
Scandinavian Journal of Clinical and Laboratory Investigation, 2000The 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.

Porphyrins. VIII. A stepwise synthesis of porphyrins
Australian Journal of Chemistry, 19641,2,3,4,5,6,7,8-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.

Porphyrin-lipoprotein association as a factor in porphyrin localization
Cancer Letters, 1986Systemic 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 ...
