ABSTRACT Combinatorial libraries of peptoids (oligo-N-substituted glycines) have proven to be useful sources of protein ligands. Each unit of the peptoid oligomer is derived from 2-haloacetic acid and a primary amine. To increase the chemical diversity available in peptoid libraries, we demonstrate here that heterocyclic halomethyl carboxylic acids can be employed as backbone building blocks in the synthesis of peptoid-based oligomers. Optimized conditions are reported that allow the creation of large, high quality combinatorial libraries containing these units.

    ABSTRACT: In the field of Alzheimer's disease, the development of novel biomarker assays is critically needed to improve the early diagnosis of the disease, to estimate the risk of developing the disease, to predict the rate of cognitive decline, and to monitor the response or effectiveness of a therapy. The molecular mechanisms of the disease are becoming more evident. This basic knowledge has yet to be translated into novel biomarker tools with a clinical value for general use by the community. There is therefore high interest in evaluating new technological approaches beside the classical immunoassay approach. The present paper discusses the hypothesis that there might be an adaptive immune response, unique to Alzheimer's disease, which can be visualized by the presence in body fluids of antibodies against specific analytes. Current technologies to identify such antibodies are reviewed. In addition, the major challenges to transfer discovery results of the novel antibody-based biomarker assays to a clinically relevant test will be discussed.

    ABSTRACT: The ability to monitor and manipulate antigen-specific immune responses would have a major impact on several areas of biology and medicine. In this perspective, I consider pharmacological methods to do this, with a focus on the development of abiological "antigen surrogates" capable of binding to the antigen-binding sites of antibodies and B cell receptors with high affinity and selectivity. I describe the application of combinatorial library screening to identify antigen surrogates for monoclonal antibodies of therapeutic interest using chronic lymphocytic leukemia as an example. Furthermore, I discuss the use of multiplexed assays for the quantification of antigen surrogate-antibody complexes as diagnostic tools and antigen surrogate discovery via serum screening. Although antigen surrogates are a fairly new concept, I argue that they will open new avenues for both basic and clinical research and that major advances can be expected over the next few years.
