FIELD: organic chemistry, medicine, pharmacology.

SUBSTANCE: invention relates to compound of the formula (I): or (II): wherein R¹ and R² are chosen independently from hydrogen, optionally substituted alkyl or the group: -D-E wherein R represents a covalent bond or alkylene; E represents optionally substituted alkoxy-group, optionally substituted cycloalkyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted heterocyclyl, optionally substituted alkenyl or optionally substituted alkynyl under condition that if D represents a covalent bond then E can't represents alkoxy-group; R³ represents hydrogen atom, optionally substituted alkyl or optionally substituted cycloalkyl; X represents optionally substituted arylene or heteroarylene; Y represents a covalent bond or alkylene wherein one carbon atom can be substituted optionally for -O-, -S- or -NH-, and optionally substituted hydroxy-, alkoxy-, optionally substituted amino-group or -COR wherein R represents hydroxy-, alkoxy- or amino-group under condition that if an optional substitute represents hydroxy- or amino-group then it can't be adjacent with a heteroatom; Z represents hydrogen atom, optionally substituted monocyclic aryl or optionally substituted monocyclic heteroaryl under condition that Z represents hydrogen atom only under condition that Y represents a covalent bond, and X represents optionally substituted 1,4-pyrazolene, and under condition that if X represents optionally substituted arylene then Z represents optionally substituted monocyclic heteroaryl. Also, invention describes a method for treatment of the morbid state by inhibition of adenosine receptors describes as A_2B based on compounds of the formula (I) or the formula (II). Invention provides synthesis of novel compounds possessing useful biological properties.

EFFECT: valuable medicinal properties of compounds.
