(Upper layer) CLSM pictures of NR8383 and Caco-2 cells after 24 h exposure to a non-toxic concentration of 1 μg/ml of different PNP 90 ex  = 488 nm and λ em  = 543 nm) with phase contrast figures given as inserts. (Lower layer) Relative cellular uptake of different PNP45[4] and PNP90 in NR8383 and Caco-2 cells after 24 h exposure with the PNP45-NH2 (1 μg/ml) values taken as 100 % (n = 5). The * sign signifies p < 0.05 when compared to the data for PNP45-NH2. The “†” sign signifies p < 0.05 when compared between the PNP45 and PNP90.
