between the chemical structure and cytotoxic activity of betulinic acid (1) derivatives were investigated. Eight lupane derivatives (1-8), one of them new (6), five diosphenols (9-13), four of them new (10-13), two new norderivatives (14 and 15), five seco derivatives (16-20), four of them new (16, 17, 19, and 20), and three new seco-anhydrides (21-23) were synthesized from 1, and their activities were
在这项研究中,研究了桦木酸(1)衍生物的化学结构与细胞毒性活性之间的关系。八个卢烷衍生物(1-8),其中一个是新的(6),五个二酚(9-13),其中四个是新的(10-13),两个新的正衍生物(14和15),五个山高的衍生物(16- 20),从1合成了其中的四个新化合物(16、17、19和20),以及三个新的癸二酸酐(21-23),并将它们的活性与已知化合物的活性进行了比较。取代对28位羧基的A环和羧基酯化的影响对细胞毒性具有特别的意义。在二酚9和13(TCS(50)4和5 micromol / L)和癸酸酐22和23(TCS(50)7和6 micromol / L)中发现了针对T淋巴细胞白血病细胞系CEM的显着细胞毒性活性。 。
