Abstract: The present invention relates to novel Tricyclic Heterocycle Derivatives, pharmaceutical compositions comprising the Tricyclic Heterocycle Derivatives and the use of these compounds for treating or preventing allergy, an allergy-induced airway response, congestion, a cardiovascular disease, an inflammatory disease, a gastrointestinal disorder, a neurological disorder, a metabolic disorder, obesity or an obesity-related disorder, diabetes, a diabetic complication, impaired glucose tolerance or impaired fasting glucose. R1 is formula (Ia), (Ib) or (Ic); R2 is alkvl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl or heterocycloalkyl. any of which can be optionally substituted with R11; M1 is —CH—. —C(halo)- or —N—; Y is —C(O)—, —S—. —S(O)—, —S(O)2—, —CH2— or —O—, such that Y is not —O— when an adjacent atom is N.
