Porphyrinogens

03/01/1982 - "Porphyrinogens in urine in various types of porphyrias."
07/01/1982 - "Porphyrinogens, porphyrins, and the porphyrias."
01/01/1981 - "Porphyrin biosynthesis in Euglena gracilis--IV. an endogenous factor controlling the enzymic synthesis of porphyrinogens and its possible role in the treatment of some porphyrias."
12/01/2002 - "The clinical aspect of porphyria has been investigated, and it is well known that porphyrinogens such as estrogens and alcohol or other inducers of P450 isoenzymes exacerbate the porphyric state. "
01/01/2022 - "Porphyrias are a group of rare diseases leading to dysregulation in heme biosynthesis and the accumulation of heme precursors, including porphyrinogens, which in their oxidized states [porphyrins] are reddish or purple. "

08/01/1993 - "Urinary porphyrinogens in normal subjects and in patients with porphyria cutanea tarda and acute intermittent porphyria."
03/01/1982 - "A difference was found between the excretion of porphyrinogens in morning fresh urine in porphyria cutanea tarda (average porphyrinogen fraction 22.5%, SD 10.3% of total porphyrins) and in acute intermittent porphyria (average porphyrinogen fraction 77.1%, SD 9.3% of total porphyrins). "
02/01/1986 - "Human porphyria cutanea tarda (PCT) is an unusual consequence of common hepatic disorders such as alcoholic liver disease and iron overload, where hepatic iron plays a key role in the expression of the metabolic lesion, i.e., defective hepatic decarboxylation of porphyrinogens. "

08/01/1993 - "Urinary porphyrinogens in normal subjects and in patients with porphyria cutanea tarda and acute intermittent porphyria."
03/01/1982 - "Oxidation of the urine in acute intermittent porphyria is recommended before absorption on talc and subsequent thin-layer chromatography, because porphyrinogens are not adsorbed on talc."
03/01/1982 - "A difference was found between the excretion of porphyrinogens in morning fresh urine in porphyria cutanea tarda (average porphyrinogen fraction 22.5%, SD 10.3% of total porphyrins) and in acute intermittent porphyria (average porphyrinogen fraction 77.1%, SD 9.3% of total porphyrins).
