Heme-regulated inhibitor (HRI), an eukaryotic translation initiation factor 2 alpha (eIF2α) kinase, plays critical roles in cell proliferation, differentiation, adaptation to stress, and hemoglobin disorders. HRI phosphorylates eIF2α, which couples cellular signals, including endoplasmic reticulum (ER) stress, to translation. We previously identified 1,3-diarylureas and 1-((1,4-trans)-4-aryloxycyclohexyl)-3-arylureas (cHAUs) as specific activators of HRI that trigger the eIF2α phosphorylation arm of ER stress response as molecular probes for studying HRI biology and its potential as a druggable target. To develop drug-like cHAUs needed for in vivo studies, we undertook bioassay-guided structure-activity relationship studies and tested them in the surrogate eIF2α phosphorylation and cell proliferation assays. We further evaluated some of these cHAUs in endogenous eIF2α phosphorylation and in the expression of the transcription factor C/EBP homologous protein (CHOP) and its mRNA, demonstrating significantly improved solubility and/or potencies. These cHAUs are excellent candidates for lead optimization for development of investigational new drugs that potently and specifically activate HRI.

To reduce the pro-angiogenic effects of sEH inhibition, a structure-activity relationship (SAR) study was performed by incorporating structural features of the anti-angiogenic multi-kinase inhibitor sorafenib into soluble epoxide hydrolase (sEH) inhibitors. The structural modifications of this series of molecules enabled the altering of selectivity towards the pro-angiogenic kinases C-RAF and vascular endothelial growth factor receptor-2 (VEGFR-2), while retaining their sEH inhibition. As a result, sEH inhibitors with greater potency against C-RAF and VEGFR-2 were obtained. Compound 4 (t-CUPM) possesses inhibition potency higher than sorafenib towards sEH but similar against C-RAF and VEGFR-2. Compound 7 (t-CUCB) selectively inhibits sEH, while inhibiting HUVEC cell proliferation, a potential anti-angiogenic property, without liver cancer cell cytotoxicity. The data presented suggest a potential rational approach to control the angiogenic responses stemming from sEH inhibition.
