摘要：
Human CC chemokine receptor (CCR) 5 is a G protein-coupled receptor involved in a broad range of human diseases that mediates HIV-1 viral entry into cells. Certain small molecule receptor antagonists to CCR5 have been useful in therapy for these diseases. In this study, CCR5-expressing CHO cells (CHO/CCR5 cells) were used to select CCR5-binding peptides from a phage-displayed 12-mers peptide library. All of the 30 clones selected from the library showed specific binding to CHO/CCR5 cells by enzyme linked immunosorbent assay (ELISA). Seventeen out of the 30 clones shared the amino acid motif AFDWTFVPSLIL. The motif-containing phages and synthetic peptide AFDWTFVPSLIL blocked the binding of mAb 2D7 to CHO/CCR5 cells and competitively inhibited the ability of chemokine regulated on activation normal T cell expressed and secreted (RANTES) binding to CHO/CCR5 cells. Furthermore, the peptide AFDWTFVPSLIL also inhibited RANTES induced increase in the intracellular Ca2+ level in CHO/CCR5 cells. These results suggest that the peptide AFDWTFVPSLIL was specific for CCR5 and that it might become a CCR5 antagonist.

摘要：
A molecularly imprinted polymer was synthesized using 2-(diethylamino) ethylmethacry -late(DEM) and bismethacryloyl-β-cyclodextrin(BMA-β-CD) as bi-functional monomers and norfloxacin(NOF) as a template. The results of equilibrium binding experiments indicated that the polymer has affinity and specificity for NOF in aqueous media, and that its selective recognition ability for the template was higher than that of the imprinted polymers synthesized with a single functional monomer (BMA-β-CD or DEM).
