been prepared by the Pinner method from the corresponding triazole dinitriles. Copper‐catalyzed “click chemistry” was used for the synthesis of 1,4‐ and 4,5‐substituted triazoles, aryl magnesium acetylide reagents for the 1,5‐substituted triazoles, with a thermal dipolar addition reaction employed for the 2,4‐substituted triazoles. In vitro antimalarial activity against two different PfCRT‐modified
通过Pinner方法由相应的三唑二腈制备了四个不同系列的三唑二am。铜催化的“点击化学”被用于合成1,4和4,5取代的三唑,1,5取代的三唑的芳基乙酰化镁试剂,以及2,4的热偶极加成反应取代的三唑。在针对两种不同株Pfcrt改性寄生虫线(体外抗疟活性科学 2002年,298的,210-213)恶性疟原虫确定每种化合物的血红蛋白生成抑制和抑制。鉴定了具有强纳摩尔抗疟活性的几种二am,并重新合成了选定的分子作为其二mid肟三唑的前药。这些前药之一OB216被证明在体内具有很高的效力,ED 50值为5 mg kg -1(po),观察到的100%治愈率(CD 100)仅为10 mg kg -1(口服) )在感染了文氏疟原虫的小鼠中施用。
