N3-Substituted derivatives of 2',3'-O-isopropylideneuridine (1) were synthesized and their pharmacological effects on the central nervous system (CNS) examined using mice. Methyl (2), ethyl (3), propyl (4), butyl (5), allyl (6), benzyl (7), o-, m-, p-xylyls (8, 9, 10), and alpha-phenylethyl (11) derivatives of 1 were administered to mice by intracerebroventricular (i.c.v.) injection for evaluating
合成了N3取代的2',3'-O-异丙基亚氨基尿苷(1)衍生物,并使用小鼠检查了它们对中枢神经系统(CNS)的药理作用。甲基(2),乙基(3),丙基(4),丁基(5),烯丙基(6),苄基(7),邻,间,对二甲苯基(8、9、10)和α-通过脑室内(icv)注射将1的苯乙基(11)衍生物施用于小鼠,以评估催眠活性,戊巴比妥诱导的睡眠时间延长和自发活动作为指标。通过ICV注射以2.0μmol/小鼠的剂量,只有3个具有催眠活性。化合物3、4和10与巴比妥酸盐有明显的协同作用,表明该衍生物具有一定的中枢神经系统抑制作用。而且,即使在低剂量下,3和4也会引起小鼠的自发活动降低。
