Physicochemical Properties of the Original Antidepressant GSB-106 and Development of a Method for the Analysis of GSB-106 Substance

Abstract

Studies at the V. V. Zakusov Science Research Institute of Pharmacology have worked on the basis of the β-pleated structure of loop 4 of brain-derived neurotrophic factor (BDNF) to construct its dimeric peptide mimetic - GSB-106, bis-(N-monosuccinyl-L-serine-L-lysine) hexamethylenediamide. GSB-106 is being developed as an antidepressant with a BDNF-ergic mechanism of action. We report here studies of the physicochemical properties of GSB-106 and development of a method for analysis of GSB-106 substance. The main pharmacopeia quality indicators were determined and IR and NMR spectra were obtained from samples of substance. A method was developed for detecting contaminants in substance using TLC and HPLC.
