(+/-)-2,3,5,6-Tetrahydro-6-phenylimidazo[2,1-b]selenazole (1-selenotetramisole) was prepared from 2-aminoselenazoline in a three-step synthetic sequence. Resolution with d-10-camphorsulfonic acid yielded the optical isomers which were compared with (+)- and (-)-tetramisole as inhibitors of alkaline phosphatase isoenzymes. At 8.7 X 10(-5) M the (-) isomer of both tetramisole and 1-selenotetramisole
(3-)-2,3,5,6-四氢-6-苯基咪唑并[2,1-b]硒唑(1-硒代四咪唑)是由2-氨基硒唑啉按三步合成顺序制备的。用d-10-樟脑磺酸拆分得到光学异构体,将其与(+)-和(-)-四咪唑作为碱性磷酸酶同工酶抑制剂比较。在8.7 X 10(-5)M时,四咪唑和1-硒代四咪唑的(-)异构体对牛肝和胎盘同工酶产生了显着的抑制作用,但对牛肠或人胎盘同工酶却没有产生抑制作用。(+)异构体在这些浓度下均未显示抑制作用。
