Major P-gp-mediated efflux pump modifiers are formononetin, amorphigenin, rotenone and chrysin, while MRP-mediated efflux pump modifiers are formononetin, afrormosin, robinin, kaempferol and epigallocatechin.

Moreover, known inhibitors of ETC, rotenone and antimycin A which cause an increase in reactive oxygen species, synergized with verapamil-induced collateral sensitivity leading to increased cell death as determined by MTT cell survival assay.

Epirubicin, an antineoplastic drug, is considered to be taken up by tumor cells via a common carrier by facilitated diffusion and is then pumped out in an energy-dependent manner because epirubicin is a substrate for P-glycoprotein (P-gp).
The uptake of epirubicin at a clinical concentration (7.5 x 10 (-7) M) was significantly reduced at 4 degrees C and significantly inhibited when pretreated with metabolic inhibitors (carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP), rotenone and sodium azide) by nearly 25%.

The effect of active transport was investigated using cells expressing P-glycoprotein (CEM (VBL)) and cells expressing multidrug resistance-associated protein 1 (MRP1; CEM (E1000)).
Incubations were also carried out at 4 degrees C and in the presence of 2-deoxyglucose plus rotenone to examine the effect of inhibiting active transport.

The uptake of TEL by NR8383 was inhibited by rotenone and FCCP, ATP depletors and was temperature-dependent.
These data suggest that the high distribution of TEL to AMs is due to the sustained distribution to ELF via MDR1 as well as the high uptake by AMs themselves via active transport mechanisms.

Interestingly, the effect of compound 3 was specific and irreversible to human colon adenocarcinoma SW480 cells, which overexpress the transmembrane P-glycoprotein often related to chemoresistance.
Furthermore, analysis of cellular extracts after incubation with the test compounds and rotenone (positive uptake control) demonstrated the intracellular accumulation of 1, 2, 3, and 5.

Due to the necessity of overcoming the blood-brain barrier in the treatment of brain tumours, we investigated if the new monastrol analogues are modulators or substrates of the p-glycoprotein (p-gp) 170 by a flow cytometric calcein-AM efflux assay.

Five annonaceous acetogenins, rolliniastatin-1 [structure: see text], rolliniastatin-2 [structure: see text], laherradurin [structure: see text], squamocin [structure: see text], annonacin [structure: see text], and rotenone as a reference, differing in their NADH oxidase inhibition activity, have been evaluated for antifeedant, insecticidal, trypanocidal and cytotoxic effects on insect, mammalian and tumor cells.
All the test compounds were toxic to Leptinotarsa decemlineata, demonstrated selective cytotoxicity to insect Sf9 cells and a panel of tumor cell lines with the multidrug-resistant SW480 (P-glycoprotein+, Pgp+) being the most sensitive one.

In general, these flavonoids were more effective than three classical substrates of multidrug resistance protein 1 (MK-571, indomethacin, and verapamil).
Prototypic flavonoids (2',5'-DHC and chrysin) were subsequently tested for their abilities to potentiate the toxicities of prooxidants (etoposide, rotenone, 2-methoxyestradiol, and curcumin).

Interestingly, the metabolic inhibitors, 2,4-dinitrophenol, oligomycin, rotenone, and sodium azide, markedly decreased 59Fe mobilization mediated by PIH, but had either no effect or much less effect on 59Fe release by 311.
Considering that an ATP-dependent process was involved in 59Fe release by PIH, further studies examined 4 widely used inhibitors of the multi-drug efflux pump P-glycoprotein (P-gp).

Compared with parental GC3/c1 human colon adenocarcinoma cells, which are diarylsulfonylurea (DSU)-sensitive cells, the DSU-resistant clone LYC5 demonstrates 4.2-, 12.8-, and 5.3- fold increase in sensitivity to the mitochondrial toxins rotenone, antimycin, and oligomycin, respectively.
