Abstract
OBJECTIVE: In this study, we develop and apply a high-throughput screening protocol to investigate the activity of non-ionic surfactants, with a broad range of hydrophilic-lipophilic balance values, against ABCB1-mediated efflux transport and ABCC2-mediated efflux transport.
METHODS: Caco-2 cells were grown for 7 days in 96-well plates, then washed and incubated with the test materials for 2 h in the presence of 2.5 μm of either rhodamine 123 (R-123) or 5(6)-Carboxy-2',7' dichlorofluorescein diacetate as probes of ABCB1 and ABCC2, respectively.
KEY FINDINGS: Of the surfactants tested, no activity against ABCC2 was detected and all surfactants showing efficacy against ABCB1 had a HLB value of 22 or below. Inhibition of ABCB1 was seen in the order of efficacy to be poloxamer 335 > poloxamer 40 > Crovol A-70 > Myrj S-40 > poloxamer 184 > poloxamer 182 > Etocas 40 > Tween 20 > Etocas 29 > Tween 80 > Acconon C-44 > Span 20. With regard to this inhibition, the distribution of hydrophilic regions is more important than the HLB value.
CONCLUSION: This work demonstrates a high-throughput protocol for detecting materials that can modulate ABCB1-mediated efflux. These surfactants could be exploited to improve oral delivery of drugs prone to efflux.
