In Vitro Triclopyr (3 mM; 48 hours) treatment exhibits cytotoxicity against N2a cells[1]. Cell Cytotoxicity Assay[1] Cell Line: Mouse neuroblastoma (N2a) cells Concentration: 3 mM Incubation Time: 48 hours Result: Decreased significantly for cell viability (P < 0.0001) compared to the untreated N2a cells.
In Vivo Pharmacokinetic Analysis Triclopyr exhibits moderate half-lives (dog 25 h and monkey 6.3 h) due to plasma clearance (18 mL/h/kg, 26 mL/h/kg respectively) following oral gavage (3 male beagle dogs ;0.5 mg/kg, 5 mg/kg and 20 mg/kg) and intravenous administration (1 male rhesus monkey; 30 mg/kg) [2]. Animal Model: 3 male beagle dogs(7.2 - 7.9 kg), 1 male rhesus monkey [2] Dosage: 0.5 mg/kg, 5 mg/kg, 20 mg/kg (beagle dog); 30 mg/kg (rhesus monkey) Administration: Oral gavage (beagle dog); intravenous (rhesus monkey) Result: T1/2s of 25 and 6.3 h for dogs and a monkey, respectively.
