Genomic structure of the canalicular multispecific organic anion-transporter gene (MRP2/cMOAT) and mutations in the ATP-binding-cassette region in Dubin-Johnson syndrome. (1/90)

Dubin-Johnson syndrome (DJS) is an autosomal recessive disease characterized by conjugated hyperbilirubinemia. Previous studies of the defects in the human canalicular multispecific organic anion transporter gene (MRP2/cMOAT) in patients with DJS have suggested that the gene defects are responsible for DJS. In this study, we determined the exon/intron structure of the human MRP2/cMOAT gene and further characterized mutations in patients with DJS. The human MRP2/cMOAT gene contains 32 exons, and it has a structure that is highly conserved with that of another ATP-binding-cassette gene, that for a multidrug resistance-associated protein. We then identified three mutations, including two novel ones. All mutations identified to date are in the cytoplasmic domain, which includes the two ATP-binding cassettes and the linker region, or adjacent putative transmembrane domain. Our results confirm that MRP2/cMOAT is the gene responsible for DJS. The finding that mutations are concentrated in the first ATP-binding-cassette domain strongly suggests that a disruption of this region is a critical route to loss of function.  (+info)

Iron-coproporphyrin III is a natural cofactor in bacterioferritin from the anaerobic bacterium Desulfovibrio desulfuricans. (2/90)

A bacterioferritin was recently isolated from the anaerobic sulphate-reducing bacterium Desulfivibrio desulfuricans ATCC 27774 [Romao et al. (2000) Biochemistry 39, 6841-6849]. Although its properties are in general similar to those of the other bacterioferritins, it contains a haem quite distinct from the haem B, found in bacterioferritins from aerobic organisms. Using visible and NMR spectroscopies, as well as mass spectrometry analysis, the haem is now unambiguously identified as iron-coproporphyrin III, the first example of such a prosthetic group in a biological system. This unexpected finding is discussed in the framework of haem biosynthetic pathways in anaerobes and particularly in sulphate-reducing bacteria.  (+info)

Antitumor effect of photodynamic therapy with zincphyrin, zinc-coproporphyrin III, in mice. (3/90)

We studied the antitumor effects of photodynamic therapy (PDT) with Zincphyrin, coproporphyrin III with zinc, derived from Streptomyces sp. AC8007, in vitro and in vivo. The photokilling effect of Zincphyrin in the presence of 0.78-100 microg/ml with visible light of 27.2 mW x min/cm2 for 10 min was lower than the hematoporphyrin (Hp) used as a control with L5178Y or sarcoma-180 cells. On the other hand, Zincphyrin apparently reduced tumor growth after intraperitoneal injection at doses of 12.5-50 mg/kg with light irradiation of 75.48 mW x min/cm2 for 10 min in sarcoma-180-bearing mice. Although no mice treated with Zincphyrin died, Hp did cause the death of mice. In B-16 melanoma-bearing mice, both Zincphyrin and Hp had a similar phototherapic effect. Further improvement of the phototherapic effect was observed with the continuous administration of Zincphyrin at 12.5 mg/kg per day for 3 days. The concentration of Zincphyrin in the serum reached a maximum level of 16 microg/ml within 20 min, and the concentration remained at 4.2 microg/ml at 1 hour after the onset of treatment, indicating its rapid action in the body. No animals died after the intraperitoneal administration of Zincphyrin at 100 mg/kg plus exposure to light of 10 mW x min/cm2 for 2 hours, and the body weight of the mice did not decrease. In contrast, all animals receiving 100 mg/kg of Hp under the same conditions died. These results indicate that Zincphyrin would be a useful photosensitizer with low phototoxicity.  (+info)

Characterization of mutations in the CPO gene in British patients demonstrates absence of genotype-phenotype correlation and identifies relationship between hereditary coproporphyria and harderoporphyria. (4/90)

Hereditary coproporphyria (HCP) is the least common of the autosomal dominant acute hepatic porphyrias. It results from mutations in the CPO gene that encodes the mitochondrial enzyme, coproporphyrinogen oxidase. A few patients have also been reported who are homoallellic or heteroallelic for CPO mutations and are clinically distinct from those with HCP. In such patients the presence of a specific mutation (K404E) on one or both alleles produces a neonatal hemolytic anemia that is known as "harderoporphyria"; mutations on both alleles elsewhere in the gene give rise to the "homozygous" variant of HCP. The molecular relationship between these disorders and HCP has not been defined. We describe the molecular investigation and clinical features of 17 unrelated British patients with HCP. Ten novel and four previously reported CPO mutations, together with three previously unrecognized single-nucleotide polymorphisms, were identified in 15 of the 17 patients. HCP is more heterogeneous than other acute porphyrias, with all but one mutation being restricted to a single family, with a predominance of missense mutations (10 missense, 2 nonsense, 1 frameshift, and 1 splice site). Of the four known mutations, one (R331W) has previously been reported to cause disease only in homozygotes. Heterologous expression of another mutation (R401W) demonstrated functional properties similar to those of the K404E harderoporphyria mutation. In all patients, clinical presentation was uniform, in spite of the wide range (1%-64%) of residual coproporphyrinogen oxidase activity, as determined by heterologous expression. Our findings add substantially to knowledge of the molecular epidemiology of HCP, show that single copies of CPO mutations that are known or predicted to cause "homozygous" HCP or harderoporphyria can produce typical HCP in adults, and demonstrate that the severity of the phenotype does not correlate with the degree of inactivation by mutation of coproporphyrinogen oxidase.  (+info)

Extracellular heme peroxidases in actinomycetes: a case of mistaken identity. (5/90)

Actinomycetes secrete into their surroundings a suite of enzymes involved in the biodegradation of plant lignocellulose; these have been reported to include both hydrolytic and oxidative enzymes, including peroxidases. Reports of secreted peroxidases have been based upon observations of peroxidase-like activity associated with fractions that exhibit optical spectra reminiscent of heme peroxidases, such as the lignin peroxidases of wood-rotting fungi. Here we show that the appearance of the secreted pseudoperoxidase of the thermophilic actinomycete Thermomonospora fusca BD25 is also associated with the appearance of a heme-like spectrum. The species responsible for this spectrum is a metalloporphyrin; however, we show that this metalloporphyrin is not heme but zinc coproporphyrin. The same porphyrin was found in the growth medium of the actinomycete Streptomyces viridosporus T7A. We therefore propose that earlier reports of heme peroxidases secreted by actinomycetes were due to the incorrect assignment of optical spectra to heme groups rather than to non-iron-containing porphyrins and that lignin-degrading heme peroxidases are not secreted by actinomycetes. The porphyrin, an excretory product, is degraded during peroxidase assays. The low levels of secreted peroxidase activity are associated with a nonheme protein fraction previously shown to contain copper. We suggest that the role of the secreted copper-containing protein may be to bind and detoxify metals that can cause inhibition of heme biosynthesis and thus stimulate porphyrin excretion.  (+info)

Neonatal-onset hereditary coproporphyria with male pseudohermaphrodism. (6/90)

The appearance of hereditary coproporphyria (HCP) before puberty is very rare, and all reported cases of early-onset HCP have been in the homozygous or the compound heterozygous state. Some have been identified as harderoporphyria, which is a rare erythropoietic variant form of HCP. These conditions can be differentiated by molecular analysis because the gene abnormality responsible for harderoporphyria seems to be unique (K404E). Early-onset HCP, not harderoporphyria, is reported with a gene mutation in the heterozygous state and male pseudohermaphrodism. It was shown that adrenal gland hypofunction resulted in male pseudohermaphrodism. This case demonstrates the possibility that abnormalities of steroid metabolism influence porphyria.  (+info)

Differentiation of porphyria cutanea tarda symptomatica from other types of porphyria by measurement of isocoproporphyrin in faeces. (7/90)

The faecal porphyrin patterns of 24 patients with porphyria cutanea tarda symptomatica (PCTS), eight patients with variegate porphyria, three patients with other types of porphyria, and 20 non-porphyrics subjects have been compared using a two-demensional thin layer chromatographic technique that separates porphyrins of the isocoproporphyrin series from other faecal porphyrins. The 'isocoproporphyrin': coproporphyrin ratio ranged from 0-1 to 5-6 for patients with PCTS, whereas in other types of porphyria and non-porphyric subjects it was 0-05 or less.  (+info)

Clinical and biochemical characteristics and genotype-phenotype correlation in Finnish variegate porphyria patients. (8/90)

Variegate porphyria (VP) is an inherited metabolic disease resulting from the partial deficiency of protoporphyrinogen oxidase, the penultimate enzyme in the heme biosynthetic pathway. We have evaluated the clinical and biochemical outcome of 103 Finnish VP patients diagnosed between 1966 and 2001. Fifty-two per cent of patients had experienced clinical symptoms: 40% had photosensitivity, 27% acute attacks and 14% both manifestations. The proportion of patients with acute attacks has decreased dramatically from 38 to 14% in patients diagnosed before and after 1980, whereas the prevalence of skin symptoms had decreased only subtly from 45 to 34%. We have studied the correlation between PPOX genotype and clinical outcome of 90 patients with the three most common Finnish mutations I12T, R152C and 338G-->C. The patients with the I12T mutation experienced no photosensitivity and acute attacks were rare (8%). Therefore, the occurrence of photosensitivity was lower in the I12T group compared to the R152C group (P=0.001), whereas no significant differences between the R152C and 338G-->C groups could be observed. Biochemical abnormalities were significantly milder suggesting a milder form of the disease in patients with the I12T mutation. In all VP patients, normal excretion of protoporphyrin in faeces in adulthood predicted freedom from both skin symptoms and acute attacks. The most valuable test predicting an increased risk of symptoms was urinary coproporphyrin, but only a substantially increased excretion exceeding 1,000 nmol/day was associated with an increased risk of both skin symptoms and acute attacks. All patients with an excretion of more than 1,000 nmol/day experienced either skin symptoms, acute attacks, or both.  (+info)

Heidi Tailifer. Artist and curator Nathan Spoor takes over Copro Gallery in Santa Monica this month for another iteration of his Suggestivism group show, an annual exhibition with a rotating roster of contemporary artists. Spoor coined the term Suggestivism during his graduate studies to describe the type of ambiguous, fantastical figurative art he was creating. He later discovered that art historian Sadakichi Hartmann used the term as early as 1890 to describe an art that is possibly more than it seems, or possibly an art that is not what it seems. The description seems apt for the collection of dreamlike, imagination-driven works in the show, featuring artists like Amy Sol, Dan May, Scott Musgrove, Heidi Tailifer, Michael Page, Hannah Yata and Marco Mazzoni. Spoor has staged past versions of the show in LA, Rome and New York. Take a look at the new work in this years rendition below.. Suggestivism opens August 16 and will be on view through September 6.. ...

1. Urinary 17-oxosteroid conjugates were measured by gas-liquid chromatography in five patients with hereditary coproporphyria.. 2. Three patients were in an acute attack and showed significantly increased excretion of sulphate or glucuronide conjugates of aetiocholanolone. There was increased excretion of several other related steroids but no consistent pattern was apparent.. 3. In the two patients in remission, excretion of urinary 17-oxosteroids was not increased.. 4. The ratio of total urinary aetiocholanolone to androsterone (5β:5α) was found to be significantly elevated for the three patients in an acute attack. Serial measurements were made in two of these patients and showed a highly significant linear correlation between this ratio and the urinary content of δ-aminolaevulic acid and porphobilinogen.. 5. These observations suggest the involvement of the 17-oxosteroids, especially aetiocholanolone, in the pathogenesis of hereditary coproporphyria. ...
Hereditary coproporphyria is one of the porphyrias, a group of diseases that involves defects in heme metabolism and that results in excessive secretion of porphyrins and porphyrin precursors. Inheritance is autosomal (usually autosomal dominant, but sometimes autosomal recessive).

MTX is a substrate of MRP2, a renal tubular transporter encoded by the ABCC2 gene. It has been shown that single nucleotide polymorphisms (SNPs) on the ABCC2 gene are associated with impairment of MTX elimination. Mutations on the ABCC2 gene are also responsible for the Dubin-Johnson syndrome, characterised by the absence of a functional MRP2 protein. Apart from hyperbilirubinaemia, the main biological perturbation observed in this disease is a typical increase of the urinary ratio of coproporphyrins I (I+ III) (UCP ratio). Our hypothesis is that the UCP ratio could be used as a biomarker of MRP2s activity, thus predicting MTX elimination. One hundred patients treated with high dose MTX will be recruited in this prospective study. Their UCP ratio will be measured before and after MTX administration and correlated with MTX clearance. A genetic analysis will be conducted to study the five more frequents SNPs of ABCC2 in each patient ...
The investigations on Theileria parva infection of cattle revealed : (1) That bilirubinaemia did occur, the highest figure for plasma bilirubin being 12 v. d. Bergh units. (2) That the yellow staining of the fat is due to the combined effect of carotinoids and bilirubin. (3) That the intensity of the yellow colour of the plasma is in part due to carotinoids, a normal constituent of the blood of cattle, especially if they be fed on food containing carotinoids. (4) That there is a definite rise in the concentration of coproporphyrin in the faeces and urine. Such a rise, however, does not necessarily mean that there is an increase in the total amount excreted as the rise may be due to the decrease in the amount of faeces passed as a result of the disease ...
Porphyrins are organic aromatic compounds composed of four pyrrole rings interconnected to each other and to the Fe2+ ion. Porphyrins are essential cofactors of many proteins including cytochrome proteins and haemoglobin and myoglobin in humans. The first step in the production of porphyrin in animals is the mitochondrial formation of delta-aminolevulinate from glycine and succinyl-CoA. In humans, this aminolevulinate is then transported to cytosol where the 4-step conversion into Coproporphyrinogen III occurs. The remaining processing of this intermediate to protoporphyrin IX and then to heme takes place in mitochondrion.. The cytochrome proteins in Plasmodium and Coccidian species such as Toxoplasma and Neospora require de novo synthesis of porphyrin. Although P. falciparum obtains heme from host haemoglobin digestion, it cannot utilise them for biosynthesis of its own porphyrin-containing proteins [1] and converts them to hemozoin [2]. The enzymes of de novo heme biosynthesis in P. falciparum ...
Water-soluble, meso-substituted porphyrins are synthesized by sulfonation or methylation of the phenyl or pyridyl groups, respectively, of some non-water-soluble functionalized porphyrins that we have recently synthesized (Can. J. Chem. 72, 1894 (1994)). Twelve anionic sulfonated and seven cationic methylpyridinium porphyrins, usually containing other functional groups (phenyl, pyridyl, nitro- and amino-phenyl), are reported on. Twelve of these porphyrins are new, and all nineteen porphyrins are characterized by H-1 NMR. UV-VIS data are presented for the isolated porphyrins, while mass spectral data are noted for selected compounds. Partition coefficients of the porphyrins in octanol-water, and the accumulation of the porphyrins in HT-29 cells of a human-cancer tumor, were measured and both were inversely related to the charges of the porphyrins. The 11 porphyrins soluble in biological buffer solutions are basically nontoxic to Chinese hamster ovary (CHO) cells in oxic or hypoxic conditions or ...

Hereditary coproporphyria is an autosomal dominant form of liver (hepatic) porphyria that is very similar to acute intermittent porphyria, although it is usually a less severe disease. It results from low levels of the enzyme responsible for the sixth step in heme production - coproporphyrinogen oxidase. This enzyme speeds the conversion of coproporphyrinogen to protoporphyrinogen. In coproporphyria, the porphyrin precursors porphobilinogen and amino-levulinic acid (ALA) accumulate, as well as the formed porphyrin coproporphyrin. This leads to abdominal pain, neuropathies, constipation, and skin changes. Treatment is dependent on the symptoms ...

1. A simple chromatographic method for the study of porphyrins in erythrocytes and blood plasma, requiring little technician time, is described. The findings in adults and neonates are presented as well as those from severely ill patients.. 2. The regular occurrence of uro-, copro- and proto-porphyrin in erythrocytes is demonstrable as well as sporadic occurrence of tri-, penta-, hexa- and hepta-carboxylic porphyrin. The method gives, however, irregular values for protoporphyrin, which seems to occur in a more labile form in some subjects than in others; this is especially the case in erythropoietic protoporphyria.. 3. In blood plasma, uroporphyrin occurs regularly, and coproporphyrin less regularly. Protoporphyrin and penta- to hepta-carboxylic porphyrin are found only occasionally.. ...
The purpose of this study is to gain a better understanding of the parameters governing the synthesis of meso-substituted porphyrins. As a result of doing so, we anticipate that better reaction conditions can be developed, which will afford porphyrins in higher yields. Porphyrins are a large class of deeply colored red or purple, fluorescent crystalline pigments, of natural or synthetic origin, having in common a substituted aromatic macrocyclic ring consisting of four pyrrole-type residues, linked together by four methine bridging groups. The structure of porphyrin has been known since the early 1900s, but discrepancies exist on how the formation of porphyrin actually occurs. Several methods have been developed for the porphyrin reaction under various conditions. Three of the most common methods for the synthesis of meso-substituted porphyrins are: the Rothemund Method, the Adler Method, and the Lindsey Method. The conditions for these reactions vary from the harsh conditions where the ...

Porphyrins are tetrapyrrolic aromatic macrocycles and ubiquitous in nature. They are excellent dyes with strong absorption in the visible region (400�700 nm) and they exhibit decent fluorescence in the red region (620�900 nm). Carbazole is a nitrogen-containing electron rich aromatic heterocycle which can be linked to porphyrins and other chromophores. This review provides an overview of the different synthetic strategies that have been employed to prepare carbazole-substituted porphyrins and carbazole-fused porphyrinoids and similar systems. It also shows that how the substitution of carbazole occurs on the porphyrin core can alter its optical and electronic features. Introduction of carbazole moieties in the porphyrin ring resulted in fused porphyrinoids with changed aromaticity and significantly altered electronic features of the molecules ...

A rapid, simple and sensitive synchronous specrtofluorimetric method has been developed for the simultaneous analysis of binary mixture of metoprolol (MTP) and felodipine (FDP). The method is based upon measurement of the synchronous fluorescence intensity of the two drugs at Δλ of 70 nm in aqueous solution. The different experimental parameters affecting the synchronous fluorescence intensities of the two drugs were carefully studied and optimized. The fluorescence intensity-concentration plots were rectilinear over the ranges of 0.5-10 μg/mL and 0.2-2 μg/mL for MTP and FDP, respectively. The limits of detection were 0.11 and 0.02 μg/mL and quantification limits were 0.32 and 0.06 μg/mL for MTP and FDP, respectively. The proposed method was successfully applied for the determination of the two compounds in their commercial tablets and the results obtained were favorably compared to those obtained with a comparison method.
Porphyrins are proteins involved in the formation of heme measured in urine. Heme is essential for the proper function of many proteins including oxygen transport, energy production, and detoxification. Proper porphyrin production is essential for our bodys capacity to detoxify toxins.. Porphyrins are particularly well suited for evaluating heavy metal toxicity. The heme pathway is a constantly-changing metabolic pathway that is active in almost every cell of the body. Disturbances in this pathway may cause an accelerated accumulation of porphyrins. It is important to know that these specific enzymes are produced in the heme pathway and are found all over the body and are highly sensitive to the presence of various toxins, creating the large accumulation of porphyrins in the pathway.. ...

Porphyrins are oxidised intermediate metabolites of haem biosynthesis. They are readily excreted in excess when they accumulate as a result of the inhibition of specific enzymes in the haem biosynthetic pathway. Haem is required for oxygen binding, transport and utilisation as well as cytochromes and electron transfer
The work presented in this thesis encompasses an investigation into a number of porphyrin species. All of this work has a central focus on analysis of the porphyrin electronic structure and within the context of photovoltaics. The first exemplar of structures encompasses a series of Zn(II) tetraphenyl porphyrins which have asymmetrically substituted meso groups. The dihedral angle between the porphyrin macrocycle and the meso binding functionality has been shown not to infer any insulating properties towards delocalisation of the excited state. It is proposed that the electron withdrawing ability of the carboxylate unit is more than sufficient to overcome the poor π-overlap between the aromatic units. The inclusion of redox active functionalities at the distal meso site is shown to affect the energy and nature of the oxidised porphyrin species. It does so without almost any effect to the excited state properties of the structure. Both of these findings are important within the context of ...

Porphyrins have been the focus of a great deal of research for over a century. Their importance is highlighted by their wide distribution in nature and their countless applications. Porphyrin analogues have also been the target for many investigations due to their potential to provide a greater understanding of porphyrinoid systems and because their modified properties may lead to new applications. With the goal of achieving new porphyrinoid systems, synthesis of a unique set of adj-dicarbaporphyrinoid systems were developed. Two classes of dicarbaporphyrinoid systems were synthesized. adj-Oxo-dibenziphlorin were prepared by reacting a dipyrrylmethane dicarboxylic acid with a series of diarylketone dialdehydes using well known MacDonald `2+2 methods. The molecules were isolated as their TFA salts due to the instability of their free base structures. These unique molecules represent a cross between porphyrins and tetraoxacalixarenes. They are cross-conjugated by design and as a result do not possess 18
