Fig. 5From: 3D-QSAR study of steroidal and azaheterocyclic human aromatase inhibitors using quantitative profile of protein–ligand interactionsComparison of experimental pIC50 values of 2-n-alkyl 1,4-androstadiene-3,7,17-trione (a) and 6-n-alkyl 4,6-androstadiene-3,17-dione (b) with computational values. The pIC50 values were calculated with (blue) or without (orange) the hydrophobic contact of the n-alkyl chain. n is the number of carbon in alkyl chainsBack to article page
