CNS depressants of the formulae IA and IB: ##STR1## in which n and p are each 0 or 1, Z.sup.- is an anion and R.sub.1, R'.sub.1, R.sub.2, R'.sub.2, R.sub.3 and R.sub.4 are optional substituents. Compounds IB may be prepared by reducing compounds IA which may be made by reacting a N-(.omega.-haloalkyl) isatoic anhydride with a cyclic pseudothiourea such as a 2-organomercapto-4,5-dihydroimidazole. Compounds IB may be also prepared by cyclizing a 1-(.omega.-haloalkyl)-2,3-dihydro-imidazo[2,1-b]quinazolin-1H-5-one. The compounds are anti-inflammatory, analgesic and immunosuppressant agents.
公式IA和IB的CNS抑制剂:##STR1##其中n和p各为0或1,Z.sup.-是阴离子,R.sub.1,R'.sub.1,R.sub.2,R'.sub.2,R.sub.3和R.sub.4是可选的取代基。化合物IB可以通过还原化合物IA制备,化合物IA可以通过将N-(ω-卤代烷基)异噁唑酸酐与环状伪硫脲(例如2-有机硫代-4,5-二氢咪唑)反应制备。化合物IB也可以通过环化1-(ω-卤代烷基)-2,3-二氢咪唑[2,1-b]喹唑啉-1H-5-酮制备。这些化合物是抗炎、镇痛和免疫抑制剂。
