“…Three complexes Mo-1 to Mo-3 ( Fig. 4 ), were synthesized, characterized, and investigated against peptidase, 3CLpro, and PLpro protein targets of SARS coronavirus, under docking mode [ 65 ]. The binding free energy ( ΔG ) of these molecules with different target proteins was calculated and obtained in the range between −7.86 and −5.09 kcal/mol for Mo-1 , -8.48 to −6.18 kcal/molfor Mo-2 , and -8.43 to −5.29 kcal/molfor Mo-3 .…”
