Inhibition of protein binding to mast cells

摘要

The invention relates to a compound inhibiting the binding of the free light chain of immunoglobin (Ig LC) to mast cells. It has been found that Ig LC is the agent responsible for the sensitization of mast cells. The compounds according to the invention can thus be used for the preparation of a drug for the treatment of a disease whose symptom is an elevated Ig LC concentration in serum or spinal fluid. The invention also relates to a method of screening a series of compounds on their ability to reduce the sensitization of mast cells.
