FIELD: chemistry.
SUBSTANCE: invention relates to compounds of formula (I) and pharmaceutically acceptable salts thereof. In formula (I): X denotes a single bond or a binding group selected from -CO, -SO2-, -CS- or -CH2-; Y denotes a single bond or a divalent binding group obtained from a cyclic structure selected from benzene, pyridine, pyrimidine, pyrazole, imidazole, thiazole, thiophene, quinoline, benzoimidazole, benzothiazole, benzopyrazole, naphthalene and benzothiophene; X and Y are simultaneously single bonds; Z denotes a hydrogen atom or a substitute selected from a group A; m equals 1 or 2; n equals 0-3; in group A and group B, R, R' and R" can, respectively and independently, be identical or different and denote a hydrogen atom or -C1-6-alkyl; said -C1-6-alkyl can be substituted with a group selected from -OH, -O(C1-6-alkyl),-CONH2, -CONH(C1-6-alkyl), -CON(C1-6-alkyl)2, -NH2, -NH(C1-6-alkyl) and -N(C1-6-alkyl)2); Sus denotes a C3-C7 saturated or a C5-C10 unsaturated hydrocarbon ring or a nitrogen-containing C3-C7 heterocyclic ring containing 1-4 nitrogen atoms or containing an additional O, S atom; said C1-6 alkylene in groups A and B can be substituted in positions 1-3 with a -N(C1-6- alkyl)2 group, values of radicals R1, A1, T, B and Q are given in the claim. The invention also relates to a pharmaceutical composition containing said compounds, a PI3K inhibitor and a medicinal agent having PI3K inhibitor properties against a proliferative diseases such as a malignant tumour.
EFFECT: high efficiency of using the compounds.
