Source Pathogens 2020 Aug. Figure 5. N-acetyl-l-cysteine (Abmole Bioscience Inc, Houston, TX, USA)
Method Cell Viability Assay
Cell Lines Caco-2 cells
Concentrations 10 mM/well
Incubation Time 6 h
Results It was shown in Figure 5A that pre-incubation of Caco-2 cells with NAC for 3 h before exposure to trophozoites could block the release of Cyt-c. The activation of CASP3 was diminished by NAC in trophozoites-treated cells

Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
