我们鉴定出疏螺旋体素(大环内酯类抗生素的成员)是芽殖酵母细胞周期蛋白依赖性激酶 Cdc28/Cln2 的抑制剂。疏螺旋体素对 Cdc28/Cln2 的 50% 抑制浓度 (IC50) 为 24 microM。此外,疏螺旋体素将单倍体和二倍体细胞阻滞在 G1 期,与 α 交配信息素无法区分,浓度不影响总蛋白质合成。尽管 CDK 活性的抑制可能不是 G1 期停滞的唯一原因,但我们的结果表明疏螺旋体素是开发高等真核生物新型 CDK 抑制剂的潜在先导化合物。
We identified borrrelidin, a member of macrolide antibiotic, as an inhibitor of a cyclin-dependent kinase of the budding yeast, Cdc28/Cln2. A 50% inhibition concentration (IC50) of borrelidin for Cdc28/Cln2 was 24 microM. In addition, borrelidin arrests both haploid and diploid cells in G1 phase at the point indistinguishable from that of alpha-mating pheromone, at concentrations not affecting the gross protein synthesis. Although the inhibition of CDK activity may not be a solo cause of the G1 arrest, our results indicate that borrelidin is a potential lead compound for developing novel CDK inhibitors of higher eukaryotes.
