SELECTIVE INHIBITORS AND ALLOSTERIC ACTIVATORS OF SPHINGOSINE KINASE

Page/Page column 83-84, (2014/08/19)
Sphingosine 1-phosphate (S1P) is involved in hyper-proliferative diseases, such as cancer and vascular remodeling in pulmonary arterial hypertension. Inhibitors of sphingosine kinase 1 and 2 (SK1 and SK2), which catalyze the synthesis of S1P, may be useful anti- proliferative agents. We have synthesized a series of sphingosine-based inhibitors of SK and SK2. Also provided in this invention are compounds that activate SK1 which can be used in diseases such as fibrosis, where intracellular S1P is anti-fibrotic.

The design, synthesis, and evaluation of the potency of new isoform-selective inhibitors of sphingosine kinases 1 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 SK1. 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.
Synthesis of aminopyridines via an unprecedented nucleophilic aromatic substitution of cyanopyridines

The direct reaction of 2- and 4-cyanopyridines with lithium amides affords good yields of the corresponding aminopyridines via displacement of cyanide. Addition of CsF accelerates the reaction and can lead to significantly higher yields.
