and has low anticancer activity in some types of cancer cells. Therefore, the development of other PF-543 derivatives is needed. Methods: We designed a structurally simplified derivative of PF-543. To primarily demonstrate that the designed structure was biologically active, 8 derivatives were synthesized by a 2-step method using the commercial starting material, and their biological activities were
背景:鞘脂即使在极低剂量下也能调节各种生理功能。特别是,免疫细胞和癌细胞可能受鞘氨醇-1-磷酸酯(S1P)水平变化的控制,并且作为一种新药物开发的主要目标,人们已经对S1P进行了长期的研究。鞘氨醇激酶(SK)使鞘氨醇磷酸化以产生S1P。S1P水平的增加促进癌细胞的生长。SK有两个同工型,SK1和SK2,它们都参与癌细胞的生长。 目的:PF-543已开发为SK1抑制剂,其非脂质结构不同于一般的SK抑制剂。PF-543具有有效的SK1抑制作用,并且在某些类型的癌细胞中具有较低的抗癌活性。因此,需要开发其他PF-543衍生物。 方法:我们设计了结构简化的PF-543衍生物。为了初步证明所设计的结构具有生物活性,使用市售起始原料通过两步法合成了8种衍生物,并对其生物活性进行了评估。 结果:合成衍生物的SK1抑制作用不高于PF-543。但是,尽管这些衍生物是通过对PF-543的简单修饰而制得的,但其抗癌活性和凋亡作用与PF-543相似。
