Abstract:
Derivatives of carbamic acid have been known to
be poisonous to mammals since long time ago.
Physostigmine, currently in use as medicine, is an
alkaloid compound of carbamic acid origin, being
known as adversely affecting cholin esterase.
In the plant, MlPC (2-isopropylphenyl-n-methylcarbamate)
with the structure similar to BPMC is also
manufactured and is white crystalline powder or flake.
