Outline of Final Research Achievements

Antihistamines are inverse agonists of histamine H1 receptor and work well to relieve symptoms of allergies including pollen fever. Antihistamines are known to show undesirable side effects caused by the low receptor selectivity and the high ability to cross the blood-brain barrier. We succeeded to crystallize histamine H1 receptor in complex with the second-generation antihistamines. The structural information of these complexes would be useful for the development of new generation antihistamines without side effects.
