In Vitro	Butibufen (0.1 μM-0.1 M; 60 min) affects cell viability and cell attachment with a high dose[2]. Butibufen (1 μM; 48 h) causes a 100% cell death after 48 h exposure[2]. Butibufen (2 μM-1 mM; 6 h) affects synthesis of albumin in hepatocytes[2]. Butibufen (0.2-0.4 mM; 6 h) impaires gluconeogenesis from lactate and significantly inhibited ureogenesis[2]. Cell Viability Assay[2] Cell Line: Hepatocytes from Sprague-Dawley male rats Concentration: 0.1 μM-0.1 M Incubation Time: 60 min Result: Showed no cell viability effects under the dose of 200 μM, but dose- and time-dependently affected cell viability with higher concentrations.
In Vivo	Butibufen (50 and 250 mg/kg; p.o. 8 and 3 h before sacrifice) affects acid phosphatase activity[3]. Animal Model: Sprague-Dawley rats[3] Dosage: 50 and 250 mg/kg Administration: Oral gavage; 50 and 250 mg/kg; 8 and 3 h before sacrifice Result: Reduced acid phosphatase activity but showed no effect on the stabilization of lysosomal membrane.
