The four 2,2,5-regioisomer counterparts of SCH 51048 were synthesized and evaluated. As with the parent series, only the two cis isomers possessed any in vitro activity, and only the activity of the isomer with the R-configuration at the tetrahydrofuran 2-carbon was significant. The activity data suggests that oxygen at only one of the two possible ring positions benzylic to the difluorobenzene participates
合成并评估了SCH 51048的四个2,2,5-区域异构体。与母体系列一样,只有两个顺式异构体具有任何体外活性,并且只有具有R-构型的异构体在四氢呋喃2-碳上的活性显着。活性数据表明,在二氟苯苄基的两个可能的环位置中只有一个的氧可有效地参与活性位点的结合。
