FIGURE 16.
(A) Binding mode of 95 docked into microtubule (green ribbon representation, PDB code: 1SA0). 95 is represented in stick model, carbons in 95 are colored wheat. Hydrogen bonds are presented as green dash lines. π-sigma interaction is presented as a white dash line. (B) Binding mode of 95 docked into Top IIα (green ribbon representation, PDB code: 5 gwk). 95 is represented in stick model, carbons in 95 are colored wheat. Hydrogen bonds are presented as green dash lines. π-π interactions are presented as white dash lines. (C) The structure and bioactivity of the representative compound 95 as microtubule and Top II dual inhibitor.
