Viability of human CNS cell lines exposed to UCB, LR, BOX A and BOX B for 4 h.

Cell line	Ctrl	UCB	LR	BOX A	BOX B
SH-SY5Y	100 ± 2.2%	93.0 ± 3.4%	109.3 ± 9.8%	108.9 ± 9.7%	105.3 ± 9.0%
HMC3	100 ± 0.8%	90.5 ± 5.8%*	104.0 ± 4.0%	101.3 ± 6.5%	101.2 ± 3.6%
U-87	100 ± 1.0%	103.8 ± 10.6%	119.6 ± 9.7%*	114.5 ± 15.1%	107.4 ± 12.4%

Cell viability was evaluated by MTT assay. Concentration of tested compounds = 25 μmol/L. Ctrl, control; UCB, unconjugated bilirubin; LR, lumirubin.

*p < 0.05 vs. Ctrl.
