  Normal and Abnormal Heme Biosynthesis. 2.¹ Synthesis and Metabolism of Type-III Pentacarboxylic Porphyrinogens:  Further Experimental Evidence for the Enzymic Clockwise Decarboxylation of Uroporphyrinogen-III

  摘要：

  Uroporphyrinogen decarboxylase catalyses the sequential decarboxylation of uroporphyrinogen-III (1) to-give coproporphyrinogen-III (2), a precursor to the hemes and chlorophylls. This involves the decarboxylation of four nonequivalent acetate side chains to produce methyl units and in principle could take place by 24 different pathways involving up to 14 intermediary porphyrinogens. In the past, seemingly contradictory data have been presented that either support an ordered "clockwise" decarboxylation pathway or a random decarboxylation process. Four pentacarboxylate porphyrinogens might be involved immediately before the formation of 2, and these compounds have been synthesized as the corresponding porphyrin pentamethyl esters via tripyrrene and a,c-biladiene intermediates. Hydrolysis of the methyl esters and reduction with 3% sodium amalgam gave the required porphyrinogens, and these were incubated with crude enzyme preparations derived from chicken red cell hemolysates. One of these pentacarboxylate porphyrinogens (5dab) consistently proved to be a much better substrate than the other three, providing new support for the "clockwise" pathway for coproporphyrinogen-III formation.

  Prodigiosenes, possessing a 4-methoxypyrrolyldipyrrin skeleton, are known for their anti-cancer activity. Structural modification of the C-ring resulted in a series of prodigiosenes that displayed promising activity against leukemia cell lines during in vitro analysis against the NCI 60 cancer cell line panel. Further in vivo studies of these compounds using the zebrafish model showed persistence of anti-leukemia properties in human K562 chronic myelogenous leukemia cells.
