Novel conformationally restricted diamine derivatives containing imidazolidinylidene propanedinitrile were synthesized and evaluated for human and rat histamine H(3) receptor (H(3)R) binding affinities. Among them, compounds 2b, 2c, 2j, 2k and 2m were found to be potent ligands for both H(3)Rs with K(i) values in the sub-nanomolar range, and showed potent H(3) receptor antagonism.
合成新型构象受限的二胺衍生物,含咪唑烷基亚吡喃丙烷,并对人和大鼠组胺H(3)受体(H(3)R)的结合亲和力进行评估。其中,化合物2b,2c,2j,2k和2m被发现是两个H(3)Rs的有效配体,其K(i)值均在亚纳摩尔范围内,并显示出有效的H(3)受体拮抗作用。
