ABSTRACT
Tumor necrosis factor receptor-associated factor 6 (TRAF6) is an E3 ligase which takes part in different cellular pathways. TRAF6 is seen to be highly expressed in various cancers and most importantly is known to drive cancer metastasis. This makes TRAF6 a potential therapeutic target. In our previous studies, we observed that the C-terminal domain of TRAF6 forms a mushroom shaped trimer structure. Lys340 and Glu345 were identified to be the most critical residues in the trimer interface. In this current work, we screened for more than 14000 small molecules derived from various natural sources and they were screened against TRAF6 C-terminal trimer interaction interface to prevent the formation of the interface. All the obtained molecules were tested for their drug-likeliness properties. The ligands which qualified the filter were considered for protein-ligand docking or structure based virtual screening in GOLD 5.2. Pose selection was carried out on the basis of GoldScore and ChemScore function of GOLD 5.2. Top 20 molecules binding the TRAF6 trimeric interface were tested for their ADME properties. From the top 20 molecules, top 3 ligands were chosen based on their abilities to pass the maximum numbers of ADME filters.
