Decarboxylation of uroporphyrin by heating at atmospheric pressure.
نویسنده
چکیده
Free uroporphyrin is decarboxylated by heating in the air to 150--200 degrees C. Complete decarboxylation occurs after heating to 200 degrees C for 5 min, with a yield of 66--75%. Heptacarboxylic porphyrin can be prepared with a yield of 40% by heating uroporphyrin to 150 degrees C for 60 min, and hexacarboxylic porphyrin with a yield of about 20% by heating to 150 degrees C for 2h.

Hepta-, hexa-, and pentacarboxylic porphyrins of porphyria cutanea tarda. II. Preparation of the porphyrins by stepwise decarboxylation ofuroporphyrins.
Hepta-, hexa-, and pentacarboxylic porphyrins have been detected in porphyric as well as normal urine samples. From the former they have been isolated and converted into pure methyl esters (1). For a better understanding of the chemistry of these porphyrins, pure uroporphyrin I and uroporphyrin III were separately subjected to decarboxylation under controlled conditions. The decarboxylation pro...

Oral administration of a commercial PCB mixture to chickens caused a hepatic-type porphyria characterized by hepatic accumulation and urinary excretion of uroporphyrin. To clarify the mechanism of the porphyrinogenic activity of these PCBs, we studied the structural requirement of synthetic PCB for porphyrinogenic activities by using the cultured chick embryo liver cells and examined the relati...
متن کاملBase-mediated carboxylation of unprotected indole derivatives with carbon dioxide.
A simple and straightforward method for the preparation of indole-3-carboxylic acids was discovered through the direct carboxylation of indoles with atmospheric pressure of carbon dioxide (CO(2)) under basic conditions. The key for the reaction was found to be the use of a large excess of LiO(t)Bu as a base to suppress the undesired decarboxylation side reaction.

The main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the Qeshm Channel. For this purpose, the curves of the pressure on the Persian Gulf and Oman Sea, during the passing of the atmospheric low pressure system, are extracted across the region. During the time of occurrence of these events, sea level oscillations in the coastal areas of...

Porphyria cutanea tarda (PCT) is characterized biochemically by excessive hepatic synthesis and urinary excretion of uroporphyrin I. Clinical evidence has implicated iron in the pathogenesis of PCT. The synthesis of the normally occurring isomer of uroporphyrin, namely uroporphyrin III, from porphobilinogen (PBG) requires two enzymes; uroporphyrinogen I synthetase and uroporphyrinogen III cosyn...
