  • Publication number: 20080293587
    Abstract: The present invention relates to a method of screening a biological target for transient weak interactions between the target and a library of ligands. The method includes the provision of a composition comprising a biological target and the provision of a plurality of stationary phases from such a composition. A plurality of ligand compositions is transported to the stationary phases to establish contacts between the ligands and the biological targets. Zonal retardation information are collected for each ligand, downstream of the stationary phases in order to select ligands with dissociation constants (Kd) in the range of 0.01 to 10 mM, exhibiting weak affinity to the target.

  • Patent number: 6642249
    Abstract: The present invention relates to a novel heterocyclic compound, a pharmaceutical composition comprisining said compound, a method and use of said compound for clinical treatment of medical conditions which may benefit from immunomodulation, e.g. rheumatoid arthritis, multiple sclerosis, diabetes, asthma, transplantation, systemic lupus erythematosis and psoriasis. More particularly the present invention relates to novel heterocyclic compounds, which are CD80 antagonists capable of inhibiting the interactions between CD80 and CD28. A method of screening compounds for their ability of inhibiting ligand-induced co-stimulatory receptor internalization pathways in immune competent human cells is described. Said immune competent human cells are incubated at conditions capable of inducing co-stimulatory receptor internalization in the presence of at least one test compound and the suppression of the ligand-induced co-stimulatory receptor internalization determined.
