Synthesis and Structure–Activity Relationship of (E)-Phenoxyacrylic Amide Derivatives as Hypoxia-Inducible Factor (HIF) 1α Inhibitors
摘要:
A series of (E)-phenoxyacrylic amide derivatives were synthesized and evaluated as hypoxia inducible factor (HIF) la inhibitors. The present structure activity relationship study on this series identified the morpholinoethyl containing ester 4p as a potent inhibitor of HIF-1 alpha under hypoxic conditions (IC50 = 0.12 mu M in a cell-based HRE reporter assay) in HCT116 cells. The representative compound 4p suppressed hypoxia-induced HIF-1 alpha accumulation and targeted gene expression in a dose-dependent manner. The effect of HIF-l alpha inhibition by 4p was further demonstrated by its inhibitory activity on in vitro tube formation and migration of cells, which may be valuable for development of novel therapeutics for cancer and tumor angiogenesis.
A novel and highly efficient approach for the synthesis of aryl amides in high yields by the reaction of carboxylic acids and isocyanides in methanol at ambient temperature is reported.

The impact of various secondary and tertiary pharmacophores on in vitro potency of soluble epoxide hydrolase (sEH) inhibitors based on the unsymmetrical urea scaffold 1 is discussed. N,N'-Diaryl urea inhibitors of soluble epoxide hydrolase exhibit subtle variations in inhibitory potency depending on the secondary pharmacophore but tolerate considerable structural variation in the second linker/tertiary pharmacophore fragment.
