In Silico study showing that andrographolide binds strongly to the SARS-CoV-2 spike protein receptor-binding domain (RBD). Authors used molecular docking and dynamics simulations to demonstrate that andrographolide forms stable non-covalent interactions with the RBD, leading to conformational changes that stabilize the complex. The ligand-bound RBD showed reduced conformational fluctuations compared to the unbound form, suggesting potential interference with ACE2 receptor binding and viral entry.
22 preclinical studies support the efficacy of andrographolide for COVID-19:
Bhattarai et al., 10 Feb 2023, peer-reviewed, 3 authors.
In Silico studies are an important part of preclinical research, however results may be very different in vivo.
