structure-activity relationships of our study into a series of thiosemicarbazone derivatives of madurahydroxylactone as potential nonsteroidal inhibitors of the enzyme estrone sulfatase. The most active compound, the cyclohexylthiosemicarbazone, was shown to be a non-competitive inhibitor with a K(i) of 0.35microM. This compound is devoid of estrogenic properties and showed low acute toxicity in the hen's
马杜拉羟基内酯(MHL)是土壤细菌野紫菜(Nonomuria rubra)产生的次生代谢产物,属于苯并[a]萘并醌类。我们报告的初步结果和我们的研究成一系列的马杜拉羟基内酯的硫半脲衍生物作为潜在的非甾体类雌激素硫酸酯酶抑制剂的结构活性关系。活性最高的化合物,环己基硫代半脲,显示为非竞争性抑制剂,K(i)为0.35microM。该化合物缺乏雌激素特性,在母鸡的可育卵筛查试验中显示出较低的急性毒性。
