Science & Ingredients
Comprehensive molecular analysis of Nutravir's™ pan-protease defense technology. A detailed examination of bioactive compounds, mechanisms of action, and synergistic interactions supporting immune function during viral challenges.
Molecular Mechanisms of Action
Understanding how Nutravir's™ botanical compounds interact with viral proteases and immune signaling pathways at the molecular level to support natural defense mechanisms.
3CL Protease Inhibition
Baicalin and baicalein demonstrate direct binding affinity to viral 3CL proteases through hydrogen bonding and π-π stacking interactions. Crystal structure studies reveal multiple binding sites within the enzyme active site pocket.
RNA Polymerase Modulation
Baicalein exhibits inhibitory activity against viral RNA-dependent RNA polymerase (RdRp) through allosteric binding mechanisms, disrupting viral replication machinery across multiple virus families.
NLRP3 Inflammasome Regulation
Black rice anthocyanins (C3G and P3G) modulate NLRP3 inflammasome activation through ASC oligomerization inhibition and caspase-1 activity regulation, supporting balanced inflammatory responses.
