Bioactivity

• Target IC50:
  HepG2 cells:108.6 µg/ml|COX-2:25.8 μM|COX-1:113.7 μM|MCF-7 cells:108.4 µg/ml|COX-3:64 μM
• In Vivo:
  METHODS: To detect hepatotoxicity in vivo, Acetaminophen was administered intraperitoneally to mice (300 mg/kg) and rats (1 g/kg). RESULTS: Extensive liver necrosis was observed in mice, but little damage was observed in rat samples. The rats were highly resistant to Acetaminophen-induced liver injury. METHODS: To test for in vivo hepatotoxicity, Acetaminophen was administered to aged and weakened mice acutely (300 mg/kg by gavage), chronically (100 mg/kg by diet once daily for six weeks), or subacutely (250 mg/kg by gavage three times daily for three days). RESULTS: There was no overall increase in Acetaminophen hepatotoxicity with age or frailty in mice, despite changes in certain pathways that would be expected to affect susceptibility to Acetaminophen toxicity.

• In Vitro:
  METHODS: Non-melanoma and melanoma cell lines were treated with Acetaminophen (100 µM) for 48 h and cell viability was measured using MTT Assay. RESULTS: Acetaminophen showed considerable toxicity in melanoma cell lines SK-MEL-5, MeWo, B16-F0 and B16-F10, resulting in 40±3%, 45±7%, 66±8% and 60±5% cytotoxicity, respectively. Acetaminophen showed negligible toxicity at 100 μM in the non-melanoma cell lines PC-3, BJ, Saos-2 and SW-620 cells. METHODS: Neuroblastoma cells SH-SY5Y were treated with Acetaminophen (2 mM) for 24-48 h, and the expression levels of target proteins were detected using Western Blot. RESULTS: Acetaminophen induced cytochrome c release from mitochondria in a time-dependent manner, reaching a maximum level after 48 h of treatment. In addition, immunoblot analysis of cytoplasmic and mitochondrial fractions showed that Acetaminophen was able to induce the accumulation of Bax into mitochondria at 24 h after treatment.

• Cell Research:
  Cells are exposed to Acetaminophen for 48 hours. Cell viability is determined by the trypan blue exclusion method. Intracellular GSH is measured by recording the disulfide, GS-TNB and 5-thio-nitrobenzoic acid (TNB), the yellow colored compound formed by the reaction between GSH with DTNB.(Only for Reference)
