Description:

WARNING: This product is for research use only, not for human or veterinary use.

Ac-FLTD-CMK is a potent and selective inhibitor of caspases 1, 5 and 4. Ac-FLTD-CMK administration significantly downregulated caspase-1 p20, caspase-11 p20, GSDMD N-terminal, IL-1β, and IL-18 expression; reduced LDH release; alleviated neuronal death; attenuated brain edema and blood-brain barrier damage; and improved neurobehavioral function in mice following traumatic brain injury.
