Taking into consideration of the biological activity of betulinic acid derivatives containing a oxadiazole ring, the semisynthetic betulinic acid-1,2,4-oxadiazole esters (14–25) were synthesized starting from betulinic acid (1) and 5-(bromomethyl)-3-aryl-1,2,4-oxadiazoles (2–13) and final compounds were tested for cytotoxic activity on three human cancer cell lines in vitro. All tested compounds showed
考虑到含有恶二唑环的桦木酸衍生物的生物活性,从桦木酸(1)和5-(溴甲基)-开始合成半合成的桦木酸-1,2,4-恶二唑酯(14-25)。 3-芳基-1,2,4-恶二唑(2-13)和最终化合物细胞毒活性进行了测试在三个人类癌细胞系的体外。所有测试的化合物均显示出良好的细胞毒性活性。基于红外(IR),核磁共振(NMR)和质谱法建立合成的化合物的结构。
