Definitions

• This invention relates to a combination of a histamine H 1 receptor antagonist and a selective histamine H 4 receptor antagonist for the treatment of a range of diseases that may be treated by antagonism of either or both of the H 1 and H 4 receptors including allergic diseases and disorders such as allergic rhinitis and asthma, to the uses of, and to compositions, products and methods of treatment including, such a combination.
• This invention also relates to a selective histamine H 4 receptor antagonist. Allergies are widespread and affect a large proportion of the world population. They may be seasonal in nature and can be caused by a variety of factors present in the environment such as pollen, mites and dust particles.
• Symptoms of allergic rhinitis which may be seasonal or perennial, can include rhinorrhea, nasal congestion and irritation, often accompanied by coughing or sneezing. Irritation and soreness of the throat and eyes is also common. The level of severity of each symptom experienced may vary from representing a minor problem to a person experiencing a severe effect.
• a histamine H 1 receptor antagonist in the treatment of allergic rhinitis is well-documented but when administered alone it does not provide an effective relief for nasal blockage and such agents are therefore often administered concurrently with sympathomimetic amine decongestants such as phenylpropanolamine and pseudoephedrine.
• sympathomimetic amine decongestants such as phenylpropanolamine and pseudoephedrine.

• the term “homologue” covers homology with respect to structure and/or function. With respect to sequence homology, there is at least 70%, preferably at least 75%, more preferably at least 80%, more preferably at least 85%, more preferably at least 90%, more preferably at least 95% homology to the sequence shown in SEQ ID NO: 2. Most preferably there is at least 98% homology to the sequence shown in SEQ ID NO: 2.
• This polypeptide corresponds to the orphan G-protein-coupled receptor encoded GPRv53, that has been surmised to be a novel histamine H 4 receptor, as described in The Journal of Biological Chemistry, 275(47), 36781-36786 (November 2000), the teaching of which is incorporated herein by reference.

• membranes can be prepared from tissues or cells which naturally express either the histamine H 3 and/or H 4 receptor. Affinity can be assessed at either receptor by assessing the ability of ligands to inhibit the binding of a suitable radioactively labelled ligand to membranes containing either the histamine H 3 or H 4 receptor. The potency of compounds is compared by calculating their pK, values.
• the functional activity of ligands to determine agonist or antagonist activity is determined in whole cells expressing either the H 3 or H 4 receptor.
• Agonists full or partial are identified as agents which inhibit forskolin stimulated cyclic AMP production which can be measured directly (as cyclic AMP) or indirectly as changes in beta-lactamase activity in cells co-expressing the CRE-beta-lactamase reporter system and the appropriate histamine receptor. Agonist activities may be expressed as IC 50 values.
• Inverse agonists can also be identified by the inhibition of the basal cAMP activity (i.e. in the absence of forskolin).
• Agents which have no effect on forskolin stimulated cAMP or inhibit basal cAMP may be antagonists and such activity can be measured in an assay where cells are pre-incubated with the ligand of interest and their ability to inhibit H 3 or H 4 agonist-induced reduction of forskolin stimulated cyclic AMP is measured as described above.
• the experiments can be performed in one of two ways. Firstly, by increasing the concentration of antagonist versus fixed concentration of agonist and calculating the IC 50 for each antagonist.
