Effect of NAPA on cell viability. Cellular viability was assessed by MTT (3- [4,5-dimethylthiazol-2-yl]-2,5-di-phenyltetrazolium bromide) method after 24, 48 and 96 hours, with different concentrations of NAPA as indicated. NAPA, 2-(N-Acetyl)-L-phenylalanylamido-2-deoxy-β-D-glucose; OD, optical density.
