INCB 3284

Animal experiment:

Mice[2]Male C57Bl/6 mice (20 to 25 g) are given free access to water and rodent chow and are housed in constant temperature, humidity, and 12 h light-dark cycling. Acute liver failure is induced via a single intraperitoneal (ip) injection of 100 mg/kg of azoxymethane (AOM). In parallel, systemic inhibition of CCR2 and CCR4 activity is accomplished via pretreatment with INCB 3284 (1 mg/kg/day ip) or C021 (1 mg/kg/day ip) for 3 days prior to injection of AOM. Following injection, mice are placed on heating pads adjusted to 37°C and monitored frequently for signs of neurological decline. To reduce the impacts of hypoglycemia and dehydration, cage floors are supplied with hydrogel and rodent chow and after 12 h, and every subsequent 4 h, mice are injected subcutaneously with 5% dextrose in 250 μL of saline. If mice undergo a 20% or greater weight loss they are removed from the study[2].
