由于现有抗真菌药物的疗效有限,治疗威胁生命的隐球菌性脑膜炎 (CM) 极具挑战性。抗抑郁药舍曲林 (SER) 已被提议作为 CM 的潜在抗真菌剂。然而,临床研究表明SER未能达到预期的治疗效果。在此,通过支架跳跃设计了新型 SER 衍生物,它们在体外和体内均显示出改善的抗隐球菌活性。特别是,化合物D16被鉴定为具有新的抗真菌作用模式的有前途的抗 CM 剂。它的作用是通过抑制 Δ 5,6来阻断麦角甾醇的生物合成-去饱和酶。该研究为CM治疗提供了一个新的靶点和类药物候选者。

The present invention relates to a class of pyridazinones of formula I, which comprises 6-[3-(trifluoromethyl)phenyl]pyridazin-3(2H)-one as a mother nucleus, the preparation method thereof and the use thereof in manufacturing medicaments against tumors, especially liver cancer.
An unprecedented tandem trifluoromethylsilylation/intramolecular SN2 substitution sequence was realized by using bifunctional reagent Me2(CH2Cl)SiCF3, allowing efficient construction of valuable trifluoromethylated oxasilacyclohexanes that are difficult to access by known methods. Initial attempts into developing asymmetric variant reveal that using cinchonine-derived dimeric PTC catalyst could afford
通过使用双功能试剂 Me 2 (CH 2 Cl)SiCF 3实现了前所未有的串联三氟甲基硅烷化/分子内 S N 2 取代序列,从而可以高效构建已知方法难以获得的有价值的三氟甲基化硅氧烷环己烷。开发不对称变体的初步尝试表明,使用辛可宁衍生的二聚 PTC 催化剂可以提供高达 92% 对映体过量的手性硅氧烷环己烷。
