The molecular network analysis using Cytoscape further highlighted the protein–protein interaction of the 7 core targets, including solute carrier family 6 member 3 (SLC6A3), gamma-aminobutyric acid receptor subunit pi (GABRP), butyrylcholinesterase (BCHE), cytochrome P450 3A4 (CYP3A4), 17-beta-hydroxysteroid dehydrogenase type 2 (HSD17B2), progesterone receptor (PGR), and gamma-aminobutyric acid receptor subunit delta (GABRD) of curcumol against COVID-19 and COAD (Figure 1C; Supplementary Table 1). This evidence concerns the gene SLC6A3 and COVID-19.
