"Benzylaminopurine (6\u2013BAP),as the derivative of adenine,is involved among cytokinins (CKs).CKs are phytohormones which participate in regulation of growth and development processes of plants. Methoxy and chlorine derivatives of 6-BAP show antitumor activity (inhibitors of cyclin\u2013dependent kinases) and due to this effect may be considered as potential cytostatics.The aim of this contribution is the determination of protonation constants of 6\u2013BAP and its derivatives by potentiometric method for the different experimental conditions,such as methanol content (2.5-20 v/v percentages),temperature (5-37C) and ionic strength (I=0.1-1M NaCl).To determine the thermodynamic parameters deltaH and deltaS the temperature dependence of pKa was employed.The effect of the position of methoxy and chlorine group (X is Cl or OCH3) in 2',3'and 4'on benzene ring of 6\u2013BAP was studied,too." .
