that the natural small - molecular compounds specifically targeted the 3CL pro of FIPV
Structural modification of these compounds may generate a higher anti - viral potency for the further development of a novel therapy against FIP .
These results indicated that the natural small - molecular compounds specifically targeted the 3CL pro of FIPV and inhibited its replication .
