antifungal effect of fluconazole against Candida albicans. A diastereomer of this compound was synthesized, along with various analogues. Many of the compounds were shown to enhance the antifungal effect of fluconazole against C. albicans, some with exquisite potency. One spirocyclic piperazine derivative, which we have named synazo‐1, was found to enhance the effect of fluconazole with an EC50 value
甲spiroindolinone,(1小号,3 - [R,3α [R,6α小号)-1-苄基-6'-氯-5-(4-氟苯基)-7'-甲基螺[1,2,3一个,6一个-tetrahydropyrrolo [3,4- c ]吡咯-3,3'-1 H-吲哚] -2',4,6-三酮以前被报道可增强氟康唑对白色念珠菌的抗真菌作用。合成了该化合物的非对映异构体以及各种类似物。已显示许多化合物可增强氟康唑对白色念珠菌的抗真菌作用。s,有些具有精美的效能。发现一种螺环哌嗪衍生物,我们称为synazo-1,可增强氟康唑对敏感白念珠菌的EC 50值为300 p M的作用,对某些抗性菌株的作用低至2 n M。Synazo-1与氟康唑具有真正的协同作用,在测试菌株中FIC指数低于0.5。与抗真菌协同作用所需的浓度相比,Synazo-1在哺乳动物细胞中的毒性较低。
