BD-AcAc2
Based on 1 Customer Validation
BD-AcAc2 (R,S-1,3-Butanediol acetoacetate diester) is an orally active, CNS-penetrant antiepileptic agent. BD-AcAc2 inhibits NF-κB, NLRP3 inflammasome, caspase-1/3, pyroptosis, apoptosis, and enhances autophagy. BD-AcAc2 exhibits antioxidant activity by modulating ROS, MDA, SOD, and GSH levels, and alleviates oxidative stress. BD-AcAc2 mitigates chronic colitis, counteracts Dextran Sodium Sulfate (DSS)-induced pathology, protects against central nervous system oxygen toxicity and acute lung injury, and exhibits anti-seizure efficacy. BD-AcAc2 can be used for the research of colitis, sarcopenia, acute lung injury, seizure, and obesity.

Biological Activity

NLRP3 inflammasome |
BD-AcAc2 (4% w/w; p.o.; 24 days) induces nutritional ketosis in healthy rats without altering normal colonic structure[1].
BD-AcAc2 (25% of dietary kcals; dietary; 9 weeks) prevents age-related increases in fat mass in mice[2].
BD-AcAc2 (2.5-10 g/kg; p.o.; single dose) protects mice from central nervous system oxygen toxicity and concomitant acute lung injury in a dose-dependent manner[3].
BD-AcAc2 (4 g/kg; i.g.; single dose) significantly increases blood βHB levels and raises the PTZ seizure threshold in rats[4].
BD-AcAc2 (30% of dietary energy; p.o.; 12 weeks) reduces body weight and adiposity in HFD-induced obese mice[5].
