of the novel family of polyketides with potent cytotoxicity, antitumoral, and other biological activities. The preliminary screenings show that the IC(50) values of 2 were 1.6 x 10(-3) and 8 x 10(-2) microg/mL against HT-29 and HCT-8, respectively. A remarkable enhancement effect was observed by the activity comparison of 1c and its (4R)-hydroxylated analogue 2.
在天然存在的非丙酮生乙酸原素bulatacin的基础上,设计并合成了结构相似的非乙酸产乙酸原素的(4R)-羟基化类似物,该化合物被发现为具有强大细胞毒性,抗肿瘤和其他作用的新型聚酮化合物家族的典型成员。生物活动。初步筛选显示,针对HT-29和HCT-8的IC(50)值为2,分别为1.6 x 10(-3)和8 x 10(-2)microg / mL。通过1c及其(4R)-羟基化类似物2的活性比较,观察到了显着的增强作用。
