Structure of common phytoconstituents of Ayurvedic formulations.

Chemical structures of compounds, arranged by the target binding proteing, are shown. Compounds that bind to SARS-CoV-2 spike (S) protein (A), large protease Mpro (B), nucleocapsid (N) protein (C), Nonstructural protein Nsp15 (D), Nsp9 (E) are shown. Compounds that bind to ACE2 receptor are shown in (G). Compounds that bind to more than one relevant target are shown in F, H, I, J, K, L, M. TMPRSS2 is a co-receptor for SARS-CoV-2.
