Crystal Structure of Sphingosine Kinase 1 with PF-543.
ACS Med Chem Lett. 2014 Oct 27;5(12):1329-33. doi: 10.1021/ml5004074. eCollection, 2014 Dec 11.
The most potent inhibitor of Sphingosine Kinase 1 (SPHK1) so far identified is PF-543. The crystal structure of SPHK1 in complex with inhibitor PF-543 to 1.8 A resolution reveals the inhibitor bound in a bent conformation analogous to that expected of a bound sphingosine substrate but with a rotated head group. The structural data presented will aid in the design of SPHK1 and SPHK2 inhibitors with improved properties.
