found to suppress the synthesis of the cyclopropane-containing fatty acid dihydrosterculic acid (9,10-methyleneoctadecanoic acid) at micromolar concentrations in the growth medium, and all but the 9-thiastearate were found to inhibit the growth of the protozoa at concentrations. The most potent inhibitor, 8-thiastearic acid (I50 for growth = 0.8 microM; I50 dihydrosterculate synthesis = 0.4 microM), was
研究了其中一个亚甲基被一个硫原子取代的硬脂酸的各种类似物,作为锥虫的原生动物Crisidia fasciculata中生长和脂肪酸生物合成的抑制剂。发现8、9、10、11和11-硫代硬脂酸可抑制生长培养基中微摩尔浓度的含环丙烷的脂肪酸二氢硬脂酸(9,10-亚甲基十八碳烯酸)的合成,除发现9-thiastearate在一定浓度下能抑制原生动物的生长。还观察到最有效的抑制剂8-硫代硬脂酸(生长的I50 = 0.8 microM; I50的二氢硬脂酸酯合成= 0.4 microM),以相似的浓度抑制了γ-亚麻酸的合成。
