Evaluation of hit compounds. (a) 17 hit compounds obtained from SPR screening was evaluated by RNP assays. The highest non-cytotoxic concentration (in μM) of each compound is shown in bracket. Compounds 221 and 283 showed significant attenuation of RNP. Nucleozin was included as a positive control. (b) Compound 221 and (c) compound 283 elicited dose dependent inhibition of influenza RNP activity. (d) Compound 221 and (e) compound 283 showed dose dependent inhibition of influenza A/WSN/33 at MOI 0.01. Bar chart represents viral yield while XY curve represents cell viability. Results were obtained from three independent experiments.
