Repositioning application of polyoxyethylene (20) sorbitan monooleate on ocular drug resistance and cancer multi-drug resistance by inhibiting the ATPase activity of human multidrug resistance protein 1 and P-glycoprotein was written by Teng, Yu-Ning;Chen, Li-Hung;Chen, Yi-Hung. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2022.Name: 2,2′,2”,2”’-(((3′,6′-Dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)bis(methylene))bis(azanetriyl))tetraacetic acid This article mentions the following:
Drug efflux transporters were highly related to the clin. drug resistance issues, such as cancer multi-drug resistance (MDR) and ocular drug resistance. In the present study, with the focus on human multi-drug resistance protein 1 (MRP1) and P-glycoprotein (P-gp), the inhibitory kinetics of polyoxyethylene (20) sorbitan monooleate (Tween 80) on both drug binding sites and ATPase were in-depth evaluated. We used the stable-cloned ABCB1/Flp-In-293 and ABCC1/Flp-In-293 cell lines, and inside-out membrane vesicles for underlying mechanisms investigation while used the drug induced cancer MDR cell line KB/VIN and human retinal pigmented epithelium cell line ARPE-19 for efficacy evaluation. Results showed that Tween 80 exhibited non-competitive inhibition on the doxorubicin efflux of P-gp and MRP1, with the inhibitory affinity 0.00195% (14.89μM) and 0.00245% (18.7μM), resp. Tween 80 inhibited the basal ATPase activity of P-gp and MRP1 in a dose-dependent manner (0.0002-0.02%) and demonstrated significant reversing effects on the doxorubicin, paclitaxel, and vincristine resistance at the concentration of 0.001% (7.63μM). This was the first thorough study revealing the interactions between Tween 80 and P-gp or MRP1 at a mol. level and these findings suggested that Tween 80 was a potential candidate for future combinatorial regimens applied in the drug resistance issue. In the experiment, the researchers used many compounds, for example, 2,2′,2”,2”’-(((3′,6′-Dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)bis(methylene))bis(azanetriyl))tetraacetic acid (cas: 1461-15-0Name: 2,2′,2”,2”’-(((3′,6′-Dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)bis(methylene))bis(azanetriyl))tetraacetic acid).
