A series of new 2-[3-(2-alkyloxy-ethyl)-adamantan-1-yl]-ethoxy substituted ether phospholipids was synthesized and their antileishmanial activity was evaluated against Leishmania infantum amastigotes. The majority of the new analogues were significantly less cytotoxic than miltefosine while, antiparasitic activity depended on the length of the 2-alkyloxy substituent. The most potent compounds were
合成了一系列新的2- [3-(2-烷氧基-乙基)-
金刚烷-1-基]-乙氧基取代的醚
磷脂,并评估了其对婴儿利什曼原虫amastigotes的抗疟原虫活性。大多数新的类似物的细胞毒性明显低于米替福辛,而抗寄生虫活性则取决于2-烷氧基取代基的长度。最有效的化合物是2 - [[[3-(2-己氧基乙基)-adamant -1-基] -乙氧基] hydroxyphosphinyloxy]乙基} - Ν,Ν,Ν -三甲基-
铵内盐(5B)和2 - [[[3-(2-辛氧基乙基)-adamant -1-基] -乙氧基] hydroxyphosphinyloxy]乙基} -Ν,Ν,Ν -三甲基-
铵内盐(5c)。
