The preparation and the pharmacological evaluation of the R- and S-isomers of 3-(2-butylamino)-4H-pyrido[4,3-e]-1,2,4-thiadiazine 1,1-dioxide (BPDZ 42) and 3-(3-methyl-2-butylamino)-4H-pyrido[4,3-e]-1,2,4-thiadiazine 1,1-dioxide (BPDZ 44), two potassium channel openers, is described. Their optical purity was estimated by means of capillary electrophoresis (R- and S-BPDZ 42) and chiral HPLC (R- and
3-(2-丁基氨基)-4H-吡啶并[4,3-e] -1,2,4-噻二嗪1,1-二氧化物(BPDZ 42)的R和S异构体的制备和药理学评估描述了两个钾通道开放剂和3-(3-甲基-2-丁基氨基)-4H-吡啶并[4,3-e] -1,2,4-噻二嗪1,1-二氧化物(BPDZ 44)。通过毛细管电泳(R-和S-BPDZ 42)和手性HPLC(R-和S-BPDZ 44)估计它们的光学纯度。BPDZ 44的每个异构体的绝对构型均从晶体学数据推论得出。用BPDZ 44的R和S异构体进行的药理分析表明,它们对胰腺B细胞的活性仅有轻微差异,但对血管平滑肌细胞的活性却具有显着差异:R异构体的效力比其对应的S强6倍-异构体。在内分泌胰腺上,BPDZ 42的R-异构体比其相应的S-异构体更有效。发现S-BPDZ 44以及R-和S-BPDZ 42对胰腺和血管平滑肌组织表现出组织选择性。
