human histamine H3 receptor inverse agonists. After systematic modification of lead 1a, the potent and selective histamine H3 inverse agonist 1-(3-4-[(2S,3S)-8-methoxy-3-methyl-4,4-dioxido-2,3-dihydro-1,4-benzoxathiin-2-yl]phenoxy}propyl)pyrrolidine (5k) was identified. Compound 5k showed good pharmacokinetic profiles and brain penetrability in laboratory animals. After 3 mg/kg oral administration of
合成了一系列新颖的二氢苯并黄嘌呤衍生物,并将其评价为有效的人组胺H 3受体反向激动剂。铅1a的系统修饰后,有效的选择性组胺H 3反向激动剂1-(3- 4-[(2 S,3 S)-8-甲氧基-3-甲基-4,4-dioxido-2,3鉴定出了-二氢-1,4-苯并噻吨-2-基]苯氧基}丙基)吡咯烷(5k)。化合物5k在实验动物中显示出良好的药代动力学特征和脑穿透性。口服3k / kg的5k后,在大脑H 3含量较高的大鼠中观察到脑组胺水平显着升高 受体完全被占用。
