{Abstract}: The miRNA binds to AGO's seed region, prompting the exploration of small molecules that can offset miRNA repression of target mRNA. This miRNA-181c-5p was found to be upregulated in the chronic traumatic encephalopathy, a prevalent neurodegenerative disease in contact sports and military personals. The research aimed to identify compounds that disrupt the AGO-assisted loop formation between miRNA-181c-5p and ATM, consequently repressing the translation of ATM. Target genes from commonly three databases (DIANA-microT-CDS, miRDB, RNA22 and TargetScan) were subjected to functional annotation and clustering analysis using DAVID bioinformatics tool. Haddock server were employed to make miRNA-181c-5p:ATM-AGO complex. A total of 2594 small molecules were screened using Glide XP based on their highest binding affinity towards the complex, through a three-phase docking approach. The top 5 compounds (DB00674-Galantamine, DB00371-Meprobamate, DB00694-Daunorubicin, DB00837-Progabide, and DB00851-Dacarbazine) were further analyzed for stability in the miRNA-181c-5p:ATM-AGO-ligand complex interaction using GROMACS (version 2023.2). Hence, these findings suggest that these molecules hold potential for facilitating AGO-assisted repression of ATM gene translation.
