Fig. 3From: Anti-rheumatic colchicine phytochemical exhibits potent antiviral activities against avian and seasonal Influenza A viruses (IAVs) via targeting different stages of IAV replication cycleHalf-maximal cytotoxic concentrations (CC50) in MDCK cells and half-maximal anti-H1N1 concentrations (IC50) for the tested nitrogenous alkaloids. The CC50 and IC50 of the investigated compounds were assessed by simply plotting log inhibitor versus normalized response (variable slope) and applying the nonlinear regression analyses using GraphPad Prism 5.01 softwareBack to article page
