Abstract: Triazaspiro[5.5]undecane derivatives of the formula (I), quaternary ammonium salts thereof, N-oxides thereof, non-toxic salts thereof, or pharmaceutical compositions comprising them, as active ingredients (wherein R1 is formula (II) or formula (III); R2 is alkyl or alkynyl etc.; R3, R4 is H, (substituted) alkyl etc., or R3 and R4 together to form formula (IV); R5 is H or alkyl). Therefore the compounds of the formula (I) regulate the effect of chemokine/chemokine receptor, they are used for prevention and treatment of various inflammatory diseases, asthma, atopic dermatitis, urticaria, allergic diseases, nephritis, nephropathy, hepatitis, arthritis or rheumatoid arthritis etc.

Abstract: An intracellular calcium concentration increase inhibitor containing as the active ingredient (1) a boron compound represented by the formula (I). The compound represented by the formula (I) inhibits the increase of the intracellular calcium concentration, and therefore it is deemed to be useful as an agent for the prophylaxis and/or treatment of platelet aggregation, ischemic diseases in hearts and brains, immune deficiency diseases, allorgosis, bronchial asthma, hypertension, cerebrovascular spasm, various renal diseases, pancreatitis, Alzheimer's disease, etc.
