This invention relates to compounds which have activity as 5-HT1A agonists and antagonists which may be useful for the treatment of anxiety, depression, cognitive deficits, and prostate cancer, having the formula
wherein:
X is a moiety selected from the group of:
n is selected from the integers 1 through 5; R1 is optionally substituted aryl or mono or bicyclic heteroaryl, with a proviso that heteroaryl is not thiadiazole; R2 is H or alkyl; R3 is H, COR5, COOR5, and CONR5R6; R4 is H, alkyl, alkenyl, alkynyl, aryl, mono or bicyclic heteroaryl, aralkyl, and mono or bicyclic heteroaralkyl, wherein the aryl or heteroaryl groups are optionally substituted; R5 and R6 are H, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, adamantyl, and noradamantyl or R5 and R6 taken together may form a 5-7 membered azacyclic ring, optionally containing an additional heteroatom selected from O, S, or NR4; when R5 or R6 are chosen from cycloalkyl or cycloalkenyl, the cyclic group may optionally be substituted at the 1-position with a C1-C3 alkyl group;
or an optical isomer; or a pharmaceutically acceptable salt thereof.
本发明涉及具有5-HT1A激动剂和拮抗剂活性的化合物,可用于治疗焦虑、抑郁、认知缺陷和前列腺癌,其化学式为:其中:X是从以下组中选择的基团:n是选自1至5的整数;R1是可选取代的芳基或单环或双环杂环芳基,但杂环芳基不是噻二唑;R2是氢或烷基;R3是氢、COR5、COOR5和CONR5R6;R4是氢、烷基、烯基、炔基、芳基、单环或双环杂环芳基、芳基烷基和单环或双环杂环芳基烷基,其中芳基或杂环芳基基团可选取代;R5和R6是氢、烷基、烯基、炔基、环烷基、环烯基、金刚烷基和去甲金刚烷基,或R5和R6共同形成一个5-7成员的杂氮环,可选包含O、S或NR4等额外杂原子;当R5或R6选择自环烷基或环烯基时,该环状基团可在1-位上可选地被一个C1-C3烷基取代;或其光学异构体;或其药学上可接受的盐。
