The present invention relates to novel enolamide type compounds, pharmaceutical compositions, and methods of use thereof, useful in the treatment of diseases in which products of lipoxygenase enzyme activity or the action of leukotrienes contribute to the pathological condition.
Anti-inflammatory effects of liver X receptor (LXR) ligands are thought to be largely due to LXR-mediated transrepression, whereas side effects are caused by activation of LXR-responsive gene expression (transactivation). Therefore, selective LXR modulators that preferentially exhibit transrepression activity should exhibit anti-inflammatory properties with fewer side effects. Here, we synthesized a series of styrylphenylphthalirnide analogues and evaluated their structure activity relationships focusing on LXRs-transactivating-agonistic/antagonistic activities and transrepressional activity. Among the compounds examined, 171 showed potent LXR-transrepressional activity with high selectivity over transactivating activity and did not show characteristic side effects of LXR-transactivating agonists in cells. This representative compound, 171, was confirmed to have LXR-dependent transrepressional activity and to bind directly to LXR beta. Compound 171 should be useful not only as a chemical tool for studying the biological functions of LXRs transrepression but also as a candidate for a safer agent to treat inflammatory diseases.
Separation of α-glucosidase-inhibitory and liver X receptor-antagonistic activities of phenethylphenyl phthalimide analogs and generation of LXRα-selective antagonists
Liver X receptor (LXR) alpha/beta dual agonists are candidate medicaments for the treatment of metabolic syndrome, because their biological actions include increasing cholesterol efflux mediated by LXR beta. However, their clinical application is currently limited by their enhancing effect on triglyceride (TG) synthesis mediated by LXR alpha. Combination of an LXR alpha-selective antagonist with an LXR alpha/beta dual agonist may overcome this disadvantage. In the present work, structural development studies of phenethylphenyl phthalimide 9, which possesses LXR alpha/beta dual-antagonistic activity and alpha-glucosidase-inhibitory activity, led to the LXR alpha-selective antagonist 23f. Specific alpha-glucosidase inhibitors were also obtained. (C) 2009 Elsevier Ltd. All rights reserved.
