  Synthesis and structure-activity studies of a series of spirooxazolidine-2,4-diones: 4-oxa-analogs of the muscarinic agonist 2-ethyl-8-methyl-2,8-diazaspiro[4.5]decane-1,3-dione

  摘要：

  A series of spirooxazolidine-2,4-dione derivatives related to the putative M, agonist 2-ethyl-8-methyl-2,8-diazaspiro[4.5]decane-1,3-dione (RS86; 1) were synthesized. The compounds were evaluated as cholinergic agents in in vitro binding assays and in in vivo pharmacological tests including antiamnesic effects using scopolamine-treated mice, hypothermia, and salivation in mice. Four compounds (5a,c,f and 17a) exhibited affinity for cortical M1 receptors and reversed scopolamine-induced impairment of mouse passive avoidance tasks, as did 1. Among these compounds, only 5a exhibited M1-receptor stimulating activity in pithed rats. Structural requirements for muscarinic activity in this series of spirooxazolidine-2,4-dione derivatives were as strict as those reported for spirosuccinimide derivatives including 1. The antiamnesic dose of 3-ethyl-8-methyl-1-oxa-3,8-diazaspiro[4.5]decane-2,4-dione (5a) was 2 orders of magnitude lower than the doses inducing hypothermia and salivation, in contrast to 1 for which the former dose was only 5-10-fold lower than the latter. These results suggest that the 8-azaspiro[4.5]decane skeleton represents a useful template for designing new muscarinic agonists as antidementia drugs.

  A series of 3, 8-disubstituted-1-oxa-3, 8-diazaspiro [4, 5] decan-2, 4-diones (XI) were synthesized for pharmacological testing. 3-Substituted-8-benzyl compounds (IIIb-h), the intermediates of XI, were prepared by the following three methods : 1) condensation of methyl 1-benzyl-4-hydroxyisonipecotate (II) with urea, followed by alkylation, 2) treatment of II with isocyanates and 3) reaction of 1-benzyl-4-cyano-4-piperidinol (I) with isocyanates followed by hydrolysis. The last method was inferior to the other two methods. Reductive debenzylation of III followed by condensation with appropriate halides afforded XI. Among the compounds (XI) synthesized, 8-[3-(2-chlorophenothiazin-10-yl) propyl]-3-methyl compound (XIa) had excellent central nervous system depressing activities.
