pursuit to understand Mincle/ligand relationships and improve the pharmacologic properties of the ligands has expanded and continues to reveal new and exciting structure activity relationships. Herein we report the synthesis of novel bi-aryl trehalose derivatives in good to excellent yields. These compounds were evaluated for their ability to engage the human Mincle receptor and tested for the induction

The present invention pertains to a method for identifying a compound that can be used in mitigating and/or the treatment of a disease associated with abnormal astrocytic function, said method comprising: (i) providing a compound; (ii) determining whether said compound is a ligand for the GPR81 receptor by determining said compound's binding energy with the GPR81 receptor using molecular dynamics (MD) simulations and comparing said binding energy to the binding energy determined for a reference compound (such as L-lactate) with the GPR81 receptor; and (iii) if said compound is determined to be a ligand for the GPR81 receptor, bringing said compound in contact with a living astrocyte and determining the cAMP level in said astrocyte contacted with said compound. The present invention further pertains to an agent elevating the cAMP level in astrocytes for use in mitigating and/or in the treatment of a disease associated with abnormal astrocytic function.

Bromodomains are key transcriptional regulators that are thought to be druggable epigenetic targets for cancer, inflammation, diabetes and cardiovascular therapeutics. Of particular importance is the first of two bromodomains in bromodomain containing 4 protein (BRD4(1)). Protein-ligand docking in BRD4(1) was used to purchase a small, focused screening set of compounds possessing a large variety of core structures. Within this set, a small number of weak hits each contained a dihydroquinoxalinone ring system. We purchased other analogs with this ring system and further validated the new hit series and obtained improvement in binding inhibition. Limited exploration by new analog synthesis showed that the binding inhibition in a FRET assay could be improved to the low mu M level making this new core a potential hit-to-lead series. Additionally, the predicted geometries of the initial hit and an improved analog were confirmed by X-ray co-crystallography with BRD4(1). (C) 2015 Elsevier Ltd. All rights reserved.
