Abstract: Neprilysin due to its peptidase activity is involved in several physiological and pathological processes. Recently our group has reported the association of neprilysin with angiotensin-converting enzyme 2 (ACE2) network proteins which facilitate the entry of SARS-COV2 virus. The potential role of neprilysin beyond its peptidase activity is not known. Using the established sequence analysis and molecular docking tools, this study evaluated the molecular profile of neprilysin interaction with SARS-COV2 virus proteins. Human neprilysin protein showed a significant sequence similarity with SARS-COV2 spike protein, which was further confirmed by observation of considerable interaction in the molecular docking. Human neprilysin protein was also found to additionally interact with SARS-COV2 proteins facilitating virus replication. The potential of neprilysin inhibitors (Sacubitril and Sacubitrilat) to interfere with neprilysin and SARS-COV2 proteins interactions was assessed. The neprilysin inhibitors showed binding efficacy within therapeutically feasible concentration range (1 to 150 uM). This study while reporting a novel role of neprilysin as potential receptor for SARS-COV2 virus, highlights the merit in assessing clinical efficacy of neprilysin inhibitors for the management of SARS-COV2 infection.
