    • Methods and compositions are provided for identifying compounds having affinity or complementarity to a target molecule. Compounds according to the invention may be described by the formula E-Ca-R-Cb-A, wherein E is a therapeutic or diagnostic agent, R is a reactive group, Ca and Cb are connector groups between E and R and between R and A, respectively, and A is a group having an affinity for human serum albumin, wherein affinity group A comprises a sequence of amino acid residues -O1-O2-X1-X2-B in which the amino acid residues are independently selected from the group of all twenty naturally occurring amino acids. Compounds according to the invention may be used for labeling the target molecule, particularly where the target molecule is naturally found in a complex mixture, such as a physiological fluid, like blood. By affinity labeling in vivo, the lifetime of physiologically active entities can be greatly enhanced by becoming bound to long-lived blood components. The covalently bound entity may also serve as an antagonist or agonist of a particular binding protein or as an enzyme inhibitor.
    • 提供了用于鉴定具有与靶分子具有亲和力或互补性的化合物的方法和组合物。 根据本发明的化合物可以由式E-Ca-R-Cb-A描述,其中E是治疗或诊断剂,R是反应性基团,Ca和Cb是E和R之间的连接基团,R和 A,A是对人血清白蛋白具有亲和性的基团,其中亲和基团A包含氨基酸残基-O1-O2-X1-X2-B的序列,其中氨基酸残基独立地选自 的二十种天然存在的氨基酸。 根据本发明的化合物可用于标记靶分子,特别是当目标分子天然存在于复杂混合物如生理液体如血液中时。 通过在体内的亲和标记,生理活性物质的寿命可以通过与长寿命的血液成分结合而大大提高。 共价结合的实体还可以用作特异性结合蛋白的拮抗剂或激动剂或作为酶抑制剂。
