  • Inhibition of the binding human IgE to its receptor by tetracyclic compounds for the alleviation of IgE-mediated immune response
    Patent number: 5965605
    Abstract: Disclosed are chemical agents with unexpected activity to inhibit the interactions between human immunoglobulin E (IgE) and its receptor (Fc.epsilon.RI) which interactions are known to be involved in triggering allergic responses. The agents may be used to module the allergic response in the treatment of various clinical conditions, including rhinitis, asthma, urticaria, atopic dermatitis, and anaphylacric shock. The agents can be formulated for oral, topical or parenteral administration.
