Comparison of binding poses of 3,4-dihydroisocoumarins in P-gp obtained by molecular docking. (A) Binding poses of compounds carrying a TBS group in the side chain [(R)-19, (S)-19] versus compounds in which the TBS group was removed [(R)-19a, (S)-19a]. (B) Binding poses of compounds that carry a hydroxy group at position 8 [(R)-16, (S)-16] versus compounds that carry a methoxy group at position 8 [(R)-16a, (S)-16a]. (C) Binding modes of compounds 3, 4, 14, 14a, and 21 in comparison to (R)-19 and (S)-19.
