Evaluating the beneficial and detrimental effects of bile pigments in early and later life.

Frontiers in pharmacology

Dennery PA.
PMID: 22737125
Front Pharmacol. 2012 Jun 22;3:115. doi: 10.3389/fphar.2012.00115. eCollection 2012.

The heme degradation pathway has been conserved throughout phylogeny and allows for the removal of a pro-oxidant and the generation of unique molecules including bile pigments with important cellular functions. The impact of bile pigments on health and disease...

Biopyrrin Pigments: From Heme Metabolites to Redox-Active Ligands and Luminescent Radicals.

Accounts of chemical research

ConspectusRedox-active ligands in coordination chemistry not only modulate the reactivity of the bound metal center but also serve as electron reservoirs to store redox equivalents. Among many applications in contemporary chemistry, the scope of redox-active ligands in biology is...

Bile pigments in pulmonary and vascular disease.

Frontiers in pharmacology

Ryter SW.
PMID: 22408625
Front Pharmacol. 2012 Mar 08;3:39. doi: 10.3389/fphar.2012.00039. eCollection 2012.

The bile pigments, biliverdin, and bilirubin, are endogenously derived substances generated during enzymatic heme degradation. These compounds have been shown to act as chemical antioxidants in vitro. Bilirubin formed in tissues circulates in the serum, prior to undergoing hepatic...

Choledochus angulation by T-tube.

Castaños-Guadarrama M, Alvarado-Padilla AM, Sánchez-Fernández P.
PMID: 34520150
Rev Med Inst Mex Seguro Soc. 2020 Sep 01;58(5):622-627. doi: 10.24875/RMIMSS.M20000092.

BACKGROUND: The presence of bile stasis is a frequent mechanism for presenting choledocholithiasis and recurrence of this one. The bile duct angulation, also known as "elbow sign," could be a risk factor for reducing the flow of bile and...

J Exp Med. 1911 Jan 05;13(1):115-35. doi: 10.1084/jem.13.1.115.

These experiments indicate that, in obstructive jaundice, the bile which escapes from the liver is absorbed by the hepatic capillaries and carried by the blood to the kidneys. The presence of a thoracic duct fistula influences in no way...

MALARIAL PIGMENT (SO-CALLED MELANIN): ITS NATURE AND MODE OF PRODUCTION.

Biladienones from the photooxidation of a meso-gem-disubstituted phlorin: crystal and molecular structures of the 3N + O coordinated nickel(II) and copper(II) complexes.

Inorganic chemistry

Jeandon C, Krattinger B, Ruppert R, Callot HJ.
PMID: 11399186
Inorg Chem. 2001 Jun 18;40(13):3149-53. doi: 10.1021/ic001205b.

The photooxidation of a meso-gem-disubstituted phlorin gave two isomeric biladienones in an equilibrium involving a Z-E double bond photoisomerism. The structures of these bile pigments were elucidated using NMR techniques and show terminal benzoyl and pyrrolone moieties. Complexation with...
