  • Title: Kinetics of the intramolecular cyclization of bis(2-chlorethyl)aminoethyl esters of carboxylic acids.
    Author: Natcheva R, Manolov I, Golovinsky EV.
    Journal: Pharmazie; 1986 Sep; 41(9):642-4. PubMed ID: 3797454.
    Abstract:
    Using a direct protentiometric method the kinetics of the intramolecular cyclization of 12 synthesized bis(2-chlorethyl)-aminoethyl esters of carboxylic acids has been studied. To determine the rate constants of hydrolysis (in 50% water-ethanol medium) the model of successive reactions of first order A----B----C has been used. An attempt has been made to relate the values obtained for the rate constants with the chemical structures of the compounds studied. The kinetic characteristics have been compared to the data of the antileucemic activity of the compounds against tumor models in vivo.
