2-[(1R,2R)-2-(2,4-Difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2, 4-triazol-1-yl)propyl]-4-[4-(2,2,3,3,tetrafluoropropoxy) phenyl]-3(2H, 4H)-1,2,4-triazolone [(1R,2R)-1: TAK-187] is a new antifungal agent selected as a candidate for clinical trials. The three stereoisomers [(1S,2S)-, (1R,2S)- and (1S,2R)-1] of this compound were prepared to clarify the relationship between the stereochemistry and the
2-[((1R,2R)-2-(2,4-二氟苯基)-2-羟基-1-甲基-3-(1H-1,2,4-三唑-1-基)丙基] -4- [ 4-(2,2,3,3,四氟丙氧基)苯基] -3(2H,4H)-1,2,4-三唑酮[(1R,2R)-1:TAK-187]是一种新的抗真菌药,被选作临床试验的候选人。制备了该化合物的三种立体异构体[(1S,2S)-,(1R,2S)-和(1S,2R)-1],以阐明立体化学与生物学活性之间的关系。体外和体内抗真菌活性测定表明,TAK-187 [(1R,2R)-1]是四种立体异构体中最有效的。此外,发现TAK-187与白色念珠菌相比,对白色念珠菌的甾醇合成具有强而选择性的抑制作用。
