to eliminate the activity or effectiveness of an agent or substance.

To make inactive or inert, esp. the alteration or destruction of a biologically active agent such as pathogenic microorganisms or antigens so as to render them harmless.

to make inactive; as, boiling will inactivate most enzymes; acetylation of the antibiotic inactivated it.

Stable persistence of identity-critical structure or information in the absence of life functions. While biostasis preserves a person's original physical form in a static state, being inactivate involves someone persisting in the form of stored information specifying the structure of the person's body (or just their brain) without that body persisting.

make inactive; "they deactivated the file"
