FIGURE 1.
Inhibition of total transporter‐mediated uptake of [3H]uridine by unlabeled uridine, NBMPR, or nirmatrelvir in HeLa S3‐ENT1 or HeLa S3‐ENT2 cells. Cellular accumulation of [3H]uridine was measured after 2 min in all experiments. Data are represented as mean ± SD. Significance is indicated as *p ≤ 0.05 and ****p ≤ 0.0001.
