Story summary

Researchers from the University of São Paulo and Egyptian teams isolated galloylquinic acids from Copaifera lucens that blocked SARS-CoV-2 in lab assays.
The compounds interfered with the spike protein, inhibited papain-like protease and halted RNA polymerase, while also showing anti-inflammatory and immunomodulatory effects.
Scientists warn deforestation for luxury hotels threatens these antiviral reservoirs and say human and animal trials are needed before therapeutic use.
