  Synthesis and structural characterization of carboxyethylpyrrole-modified proteins: mediators of age-related macular degeneration

  摘要：

  Protein modifications in which the e-amino group of lysyl residues is incorporated into a 2-(omega-carboxy-ethyl)pyrrole (CEP) are mediators of age-related macular degeneration (AMD). They promote both angiogenesis into the retina ('wet AMD') and geographic retinal atrophy ('dry AMD'). Blood levels of CEPs are biomarkers for clinical prognosis of the disease. To enable mechanistic studies of their role in promoting AMD, for example, through the activation of B- and T-cells, interaction with receptors, or binding with complement proteins, we developed an efficient synthesis of CEP derivatives, that is especially effective for proteins. The structures of tryptic peptides derived from CEP-modified proteins were also determined. A key finding is that 4,7-dioxoheptanoic acid 9-fluorenylmethyl ester reacts with primary amines to provide 9-fluorenylmethyl esters of CEP-modified proteins that can be deprotected in situ with 1,8-diazabicyclo[5.4.0]undec-7-ene without causing protein denaturation. The introduction of multiple CEP-modifications with a wide variety of CEP: protein ratios is readily achieved using this strategy. (C) 2009 Elsevier Ltd. All rights reserved.

  Diagnostic methods for identifying a test subject who has or is at risk of developing age-related macular degeneration (AMD) or an analogous disease associated with oxidation of DHA-containing lipids are provided. In one aspect, the methods comprise: assaying for the presence of elevated levels of 2-(&ohgr;-carboxyethyl) pyrrole (CEP) adducts in a bodily fluid which has been obtained from the test subject. In a preferred embodiment, such methods comprise providing an antibody that is immunospecific for CEP, contacting a bodily fluid from the subject with the anti-CEP antibody, and assaying for the formation of a complex between the antibody and an antigen in the sample. In another aspect, the methods comprise assaying for the presence of elevated levels of an antibody that binds to or is immunospecific for a CEP adduct in the bodily fluid of the test subject. The present invention also relates to CEP protein and peptide adducts, an antibody reactive with a CEP adduct and a diagnostic kit comprising such antibody.

  Diagnostic methods for identifying a test subject who has or is at risk of developing age-related macular degeneration (AMD) or an analogous disease associated with oxidation of DHA-containing lipids are provided. In one aspect, the methods comprise: assaying for the presence of elevated levels of 2-(ω-carboxyethyl) pyrrole (CEP) adducts in a bodily fluid which has been obtained from the test subject.
