Design and synthesis of copper(ii) and nickel(ii) complexes as potential inhibitors against SARS-CoV-2 viral RNA binding protein and Omicron RBD protein

Two bis-Schiff base metal( ii ) complexes [Cu(L) 2 ](1) and [Ni(L) 2 ](2) were designed and synthesized as potential inhibitors for the development of new anti-SARS-CoV-2 Omicron and anti-HIV drugs.
