PF-543 is a non-sphingosine analogue with inhibitory effect against SK1, based on a Ki of 4.3 nM and 130-fold selectivity for SK1 over SK2. Since the development of PF-543, animal studies demonstrated its valuable role in multiple sclerosis, myocardial infarction, and colorectal cancer. We synthesized labeled PF-543 for biochemical studies involving SK1. Overall, the 8-step synthetic route used 3,5-dimethylphenol
PF-543是一种非鞘
氨醇类似物,对SK1具有抑制作用,其Ki为4.3 nM,对SK1的选择性是SK2的130倍。自PF-543的发展以来,动物研究证明了其在多发性硬化症,心肌梗塞和结直肠癌中的重要作用。我们合成了标记的PF-543,用于涉及SK1的生化研究。总的来说,八步合成路线使用
3,5-二甲基苯酚作为起始原料。对SK1和SK1抑制活性的对接研究证实了合成的Dansyl-PF-543和PF-543之间的结构相似性。我们还提供了Dansyl-PF-543的荧光光谱。
