TL;DR: Docking studies on both COX-1 andCOX-2 protein structures revealed that hydroxylated but not methoxylated resveratrol analogues are able to bind to the previously identified binding sites of the enzymes.

TL;DR: A set of propafenonetype substrate photoaffinity ligands has been used in this study in conjunction with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to define the substrate binding domain(s) of P-gp in more detail, and binding at domain interfaces may be a general feature of polyspecific drug efflux pumps.

TL;DR: Docking studies of selected analogues into a homology model of P-glycoprotein suggest that benzophenones show an interaction pattern similar to that previously identified for propafenone-type inhibitors.

TL;DR: This review highlights concepts for identification and optimization of new inhibitors of P-glycoprotein, which represents a promising approach for treatment of multidrug resistant tumours.

TL;DR: Inverse changes in the reactivity of TM segments 5 and 6 suggest that substrate binding and release involves a repositioning of these helices during the catalytic cycle, suggesting substrate-binding at the monomer/monomer interface.
