Figure 5. Compound AY4 directly binds to the JCPyV VP1 pentamer.

Figure 5

The direct interaction between the VP1 pentamer and AY4 was ascertained via saturation transfer difference NMR. (left) top: reference spectrum with off-resonance saturation showing the AY4 1H aromatic region resonances; bottom: difference spectrum resulting from saturation transfer to the aromatic protons of AY4. (right) the STD effect was quantified and mapped onto the structure of AY4.
