Schematic representation of the hydrophobic interaction between (a) Toddanol and human immunodeficiency virus-1-reverse transcriptase (b) Toddanone and human immunodeficiency virus-1-reverse transcriptase and (c) Toddalenone and human immunodeficiency virus-1-reverse transcriptase generated using the Ligplot program. Hydrophobic bonds are indicated by an arc with spokes radiating toward the ligand atoms they contact. The interacting atoms are those with their spokes radiating back
