Organophosphorus compounds (OPs) are widely used as pesticides, insecticides, and chemical
warfare agents (CWAs) [1-3]. These neurotoxic compounds irreversibly inhibit the enzyme acetyl-
cholinesterase (AChE), essential for central nervous system function in humans and insects,
resulting in the buildup of the neurotransmitter acetylcholine that interferes with muscular
responses, produces serious symptoms in vital organs, and eventually causes death [1-5].
