FIELD: chemistry.
SUBSTANCE: invention concerns new tricyclic derivatives of the formula (I) 
and their pharmaceutically acceptable salts, where: 1 to 3 of A1, A2, A3 and A4 are nitrogen atoms, while the rest are -CH- groups; G1 is a group selected out of -CH2-O-, -CH2-CH2-, - CH=CH-; -N(C1-C4alkyl)-CH2; G2 is a group selected out of -O-CH2-, -CH=CH-, -CH2- CH2-; R4 can be identical or different and are selected out of a group including hydrogen or halogen atoms; p are independently equal to 0, 1 or 2; Y is and optionally substituted residuum selected out of the group of alkyl, cycloalkyl, alkylaryl, alkylcycloalkylalkyl; Z is a tetrazolyl, -COOR5, -CONR5R5, NHSO2R5 or -CONHSO2R5 group, where R5 is hydrogen or optionally substituted alkyl or aryl. The invention also concerns a method of obtaining the claimed compounds.
EFFECT: possible application in treatment and prophylactics of inflammation and allergy diseases.
