文献摘要

1-苯磺酰基-5-甲氧基-N,N-二甲基色胺(3;Ki=2.3 nM)是5-HT6受体拮抗剂,去掉5-甲氧基(即6;Ki=4.1 nM)对受体亲和力影响不大。在本研究中,6的氨甲基部分可以缩短为谷氨酰胺类似物10a(Ki=3.1 nM);相关的skatole衍生物11b(ki=12 nM)也以高亲和力结合,表明色胺的氨乙基部分不是结合所必需的。化合物10a和11b代表了新型5-HT6拮抗剂的成员。
1-Benzenesulfonyl-5-methoxy-N,N-dimethyltryptamine (3; Ki=2.3 nM) is a 5-HT6receptor antagonist; removal of the 5-methoxy group (i.e., 6; Ki=4.1 nM) has little impact on receptor affinity. In the present study, it is shown that the aminomethyl portion of 6 can be shortened to gramine analogue 10a (Ki=3.1 nM); a related skatole derivative 11b (Ki=12 nM) also binds with high affinity indicating that the aminoethyl portion of the tryptamines is not required for binding. Compounds 10a and 11b represent members of novel classes of 5-HT6antagonists.
