Pe values were the mean of PAMPA measurements (n = 3–4) with ± SD.
Percent recovery (R%) measures mass retention of compounds trapped inside the PAMPA membrane.
PAMPA permeability classification: high (Pe > 1.5 × 10−6 cm/s), medium (1.0 × 10−6cm/s ≤ Pe ≤ 1.5 × 10−6 cm/s), low (Pe < 1.0 × 10−6 cm/s).
The measured Pe values are comparable to the data in ref 36.
