At end of ACL, what means "inactive"?

Hi.

ACE...

access-list ENTERPRISE_DMZ_IN extended permit ip host 172.16.1.1 host 172.16.1.5 inactive

At end of this ACL, what does the command "inactive" do?

Thank you!

meaning you add it and it inactive, 
usually this keyword is add if you have new FW and you need to complete the config then active the ACL.

I run small lab 
the R2 connect to OUT (0 level ) 
the R1 connect to IN (100 level)
you can see access-list with inactive disable the ACL and R2 can not ping R1 inside. 
immediate after I remove inactive the R2 can ping R1.

i guess you are talking about config of ASA. this happens when you deactivate the ACL via ASDM or CLI. even that available in config, it will not actively do anything in operations.
