title: Inhibition of cholinesterase by dialkylcarbamates.
abstract: The pI50 index and separation coefficients of chosen 3-N,N-diethylaminophenyl-N',N'-dialkylcarbamates were determined. Index pL50 (pI50 = negative logarithm of molar concentration of inhibitor inhibiting the enzyme activity by 50%) describes the effectiveness of the inhibitor. The rate of ability of the inhibitor to pass the blood-brain barrier is usually described by the separation coefficient in a system n-octanol/water (K(ow)). Obtained results were compared with pL50 and K(ow) of Exelon, the commercially used drug against the Alzheimer's disease.
