Structure–Activity Relationships and Molecular Modeling of Sphingosine Kinase Inhibitors
摘要:
The design, synthesis, and evaluation of the potency of new isoform-selective inhibitors of sphingosine kinases I and 2 (SK1 and SK2), the enzyme that catalyzes the phosphorylation of D-erythro-sphingosine to produce the key signaling lipid, sphingosine 1-phosphate, are described. Recently, we reported that 1-(4-octylphenethyl)piperidin-4-ol (RB-005) is a selective inhibitor of SK1. Here we report the synthesis of 43 new analogues of RB-005, in which the lipophilic tail, polar headgroup, and linker region were modified to extend the structure-activity relationship profile for this lead compound, which we explain using modeling studies with the recently published crystal structure of SKI. We provide a basis for the key residues targeted by our profiled series and provide further evidence for the ability to discriminate between the two isoforms using pharmacological intervention.
