A novel method for the partial synthesis of the rare triterpenoid, 3-epihydroxy lup-20(29)-en-19(28)-olide, and 1 from betulinic acid is reported. The binding efficiency, mode of binding for different compounds to the central catalytic domain of topoisomerase IIα, was calculated from a complete 3D molecular docking study on the crystal structure of the enzyme (1bgw, pdb). The compounds 1, 2b, and 2d
报道了一种新的方法,可从桦木酸中部分合成稀有的三萜类化合物,3-表羟基lup-20(29)-en-19(28)-olide和1。结合效率,即不同化合物与拓扑异构酶IIα的中央催化结构域的结合方式,是通过对该酶晶体结构(1bgw,pdb)的完整3D分子对接研究计算得出的。化合物1,图2b,和2d中显示拓扑异构酶II的催化活性的剂量依赖性抑制α。
