Five sparsomycin analogs (9-13) were prepared and examined for their ability to inhibit deoxyribonucleic acid (DNA) synthesis in L5178Y lymphoma cells. All of the compounds showed significant activity in the DNA synthesis assay. The compounds having RC configuration exhibited almost the same activities independently of the configuration at the sulfoxide sulfur atom. Among the SC isomers, the RS configuration was advantageous for the appearance of activity.
制备了五种稀疏霉素类似物 (9-13),并检查了它们抑制 L5178Y 淋巴瘤细胞中
脱氧核糖核酸 (DNA) 合成的能力。所有化合物在 DNA 合成测定中都显示出显着的活性。具有RC构型的化合物表现出几乎相同的活性,而与亚砜
硫原子的构型无关。在SC异构体中,RS构型有利于活性的出现。
