Topographical Mapping of Isoform-Selectivity Determinants for J-Channel-Binding Inhibitors of Sphingosine Kinases 1 and 2

Sphingosine kinase enzymes (SK1 and SK2) catalyze the conversion of sphingosine into sphingosine 1-phosphate and play a key role in lipid signaling and cellular responses. Mapping of isoform amino acid sequence differences for SK2 onto the recently available crystal structures of SK1 suggests that subtle structural differences exist in the foot of the lipid-binding "J-channel" in SK2, the structure of which has yet to be defined by structural biology techniques. We have probed these isoform differences with a ligand series derived from the potent SK1-selective inhibitor, PF-543. Here we show how it is possible, even with relatively conservative changes in compound structure, to systematically tune the activity profile of a ligand from ca. 100-fold SK1-selective inhibition, through equipotent SK1/SK2 inhibition, to reversed 100-fold SK2 selectivity, with retention of nanomolar potency.

Synthesis and biological evaluation of kresoxim-methyl analogues as novel inhibitors of hypoxia-inducible factor (HIF)-1 accumulation in cancer cells

We designed and synthesized strobilurin analogues as hypoxia-inducible factor (HIF) inhibitors based on the molecular structure of kresoxim-methyl. Biological evaluation in human colorectal cancer HCT116 cells showed that most of the synthesized kresoxim-methyl analogues possessed moderate to potent inhibitory activity against hypoxia-induced HIF-1 transcriptional activation. Three candidates, compounds 11b, 11c, and 11d were identified as potent inhibitors against HIF-1 activation with IC50 values of 0.60–0.94?μM. Under hypoxic condition, compounds 11b, 11c, and 11d increased the intracellular oxygen contents, thereby attenuating the hypoxia-induced accumulation of HIF-1α protein.

Design, synthesis, and biological evaluation of a series of alkoxy-3-indolylacetic acids as peroxisome proliferator-activated receptor γ/δ agonists We dedicate this article to Professor Young-Ger Suh on the occasion of his retirement.

Abstract A series of alkoxy-3-indolylacetic acid analogs has been discovered as peroxisome proliferator-activated receptor (PPAR) agonists. Structure-activity relationship study indicated that PPARα/γ/δ activities were dependent on the nature of the hydrophobic group, the attachment position of the alkoxy linker to the indole ring, and N-alkylation of indole nitrogen. Some compounds presented significant PPARγ/δ activity and molecular modeling suggested their putative binding modes in the ligand binding domain of PPARγ. Of these, compound 51 was selected for in vivo study via an evaluation of microsomal stability in mouse and human liver. Compound 51 lowered the levels of fasting blood glucose, insulin, and HbA1c without gain in body weight in db/db mice. When compound 51 was treated, hepatic triglycerides level and the size of adipocytes in white adipose tissue of db/db mice were also reduced as opposed to treatment with rosiglitazone. Taken together, compound 51 shows high potential warranting further studies in models for diabetes and related metabolic disorders and may be in use as a chemical tool for the understanding of PPAR biology.
