γ 磷酸从 ATP 转移到鞘氨醇 (Sph),生成小信号分子 1-磷酸鞘氨醇 (S1P),该过程由鞘氨醇激酶 (SphK) 催化,鞘氨醇激酶以两种同工型 SphK1 和 SphK2 存在。 SphK 是 S1P 和 S1P:Sph/神经酰胺比率的关键调节因子。 S1P 水平升高与镰状细胞病、癌症和纤维化等疾病有关。因此,SphK 是药物发现的潜在靶点。然而,目前验证这些酶作为药物靶点所需的化学生物学工具包还不够。通过这次综述,我们调查了体内活性 SphK 抑制剂,并强调开发更有效和选择性抑制剂的必要性。
The transfer of the gamma phosphate from ATP to sphingosine (Sph) to generate a small signaling molecule, sphingosine 1-phosphate (S1P), is catalyzed by sphingosine kinases (SphK), which exist as two isoforms, SphK1 and SphK2. SphK is a key regulator of S1P and the S1P:Sph/ceramide ratio. Increases in S1P levels have been linked to diseases including sickle cell disease, cancer, and fibrosis. Therefore, SphKs are potential targets for drug discovery. However, the current chemical biology toolkit needed to validate these enzymes as drug targets is inadequate. With this review, we survey in vivo active SphK inhibitors and highlight the need for developing more potent and selective inhibitors.
