(SAR) study from the (S,E)-eicos-4-en-1-yl-3-ol natural reference 1, the (S)-dialkynylcarbinol unit of the non-natural dehydro derivative 2 emerged as an unprecedented anti-tumoral pharmacophore. An extended study of lipidic alkynylcarbinol pharmacophores is presented, addressing additional structural parameters: Z→E isomerization of the alkenyl carbinol substituent of 1, variation of the lipidic chain
通常在天然海产品中发现的手性炔基甲醇基因其药效学特性,特别是对肿瘤细胞系的细胞毒性而成为研究热点。在从化学合成驱动四参数结构-活性关系(SAR)研究(小号,ê)-eicos -4-烯-1-基-3-醇自然参考1中,(小号的)-dialkynylcarbinol单元非天然脱氢衍生物2成为一个前所未有的抗肿瘤药效。脂质alkynylcarbinol药效的扩展研究提出,寻址附加结构参数:ž→Ë的链烯基甲醇取代基的异构化1,的脂质链长度的变异2(C 3N,Ñ = 3,4,6),氧化或的甲醇单元的取代2(以酮,叔苯基甲基甲醇,或甲基醚)中,双键的cyclomethylenation 1。这些类似物的合成所描述的,包括使用用于锌-介导的另外的(三烷基甲硅烷基)乙炔基片到ynals在存在改性Carreira的过程对映体富集的手性alkynylcarbinol衍生物的制备( - ) -或(+) - ñ -甲基麻黄碱。的12个新产品针对HCT
