Uptake of relebactam into human OAT1, OAT3 and OCT2 stably transfected cells. Time-dependent uptake of relebactam (2 μM) into MDCKII and MDCKII-OAT1 cells (a), MDCKII and MDCKII-OAT3 cells (b), and CHO-K1 and CHO-K1-OCT2 cells (c). Positive controls: uptake of [<sup>3</sup>H]PAH (1 μM) (d), [<sup>3</sup>H]ES (1 μM) (e) and [<sup>14</sup>C]TEA (1 μM) (f) for OAT1, OAT3 and OCT2, respectively, measured at 7 min. Values shown are mean ± SEM of experiments performed in triplicate. **P < 0.01; *P < 0.05. ES, estrone sulphate; PAH, p-aminohippuric acid; SEM, standard error of the mean; TEA, tetraethylammonium.

Figure 2. Uptake of relebactam into human OAT4 transiently transfected HEK293 cells. Time-dependent uptake of ... Figure 2. Uptake of relebactam into human OAT4 transiently transfected HEK293 cells. Time-dependent uptake of [<sup>14</sup>C]relebactam (10 μM) into HEK293 and HEK293-OAT4 cells pretreated with (a) or without 5 mM glutaric acid (d). Uptake in the transfected cell line was significantly different from the parental cell line (P < 0.01). Uptake of [<sup>14</sup>C]relebactam (10 μM) into HEK293 and HEK293-OAT4 cells, pretreated with (b) or without 5 mM glutaric acid (e), in the presence and the absence of probenecid (1 mM) at 15 min. Positive controls: uptake of [<sup>3</sup>H]ES (1 μM) into HEK293 and HEK293-OAT4 cells, pretreated with (c) or without 5 mM glutaric acid (f), in the presence and the absence of probenecid (1 mM) at 15 min. Values shown are mean ± SEM of experiments performed in triplicate. ES, estrone sulphate; SEM, standard error of the mean.

Uptake of [<sup>14</sup>C]relebactam into human MATE1 and MATE2K stably transfected CHO-K1 and MDCKII cells. Time-dependent uptake of [<sup>14</sup>C]relebactam (10 μM) into CHO-K1 and CHO-K1-MATE1 cells (a), and MDCKII and MDCKII-MATE2K cells (d). Uptake in the transfected cell line was significantly different from that in the parental cell line (P < 0.05). Uptake of [<sup>14</sup>C]relebactam (10 μM) into CHO-K1 and CHO-K1-MATE1 cells in the presence and the absence of control inhibitor quinidine (100 μM) (b), and MDCKII and MDCKII-MATE2K cells in the presence and the absence of control inhibitor pyrimethamine (5 μM) (e) at 20 min. Positive controls: uptake of [<sup>14</sup>C]metformin (5 μM) into CHO-K1 and CHO-K1-MATE1 cells in the presence and the absence of control inhibitor quinidine (100 μM) (c), and MDCKII and MDCKII-MATE2K cells in the presence and the absence of control inhibitor pyrimethamine (5 μM) (f) at 20 min.
