CYCLIC N,N'-DIARYLTHIOUREAS AND N,N'-DIARYLUREAS AS ANDROGEN RECEPTOR ANTAGONISTS, ANTI-CANCER AGENT, METHOD FOR PRODUCING AND USING SAME

摘要

The present invention relates to novel cyclic N,N'-diarylureas and N,N'-diarylthioureas - androgen receptor antagonists, anti-cancer agent, pharmaceutical composition, medicament, and method for treatment of cancerous diseases, among them prostate cancer. Cyclic N,N' -diarylthioureas or N,N' -diarylureas of the general formula 1, their optical (R)- and (S)- isomers and pharmaceutically acceptable salts thereof exhibiting properties of androgen receptor antagonists have been proposed, wherein: X represents oxygen or sulfur; m = 0 or 1; R1 represents C 1 -C 3 alkyl; R2 and R3 represent hydrogen; or R2 and R3 together with C-atom they are attached to form C = O group; R4 and R5 represent hydrogen; or R4 represents hydrogen, R5 represents methyl; or R4 represents methyl, R5 represents CH 2 R6 group in which R6 represents C 1 -C 3 alkoxycarbonyl, carboxyl, hydroxyl group optionally substituted with methyl or benzyl; or R4 and R5 together with C-atom they are attached to form 5- or 6- membered heterocycle comprising at least one oxygen atom or nitrogen atom optionally substitutd with methyl; or R4 and R5 together with C-atom they are attached to form NH group.
