Abstract: An expert computer system was developed to analyze the effects of regulatory peptides (RPs) and some other biologically active compounds. The database includes information on their structures and physiological and inductive effects taking in account the method of administration, doses, and types of organisms. The developed method of vector representation of RP effects and the software modules provide for the estimation of the role of single RPs and their combinations in the regulatory system of organism. The expert system was used for solving the following tasks: (1) an analysis of the structural and functional organization of the RP continuum and a search for effective RP combinations regulating the levels of anxiety, depression, cognitive processes, etc; (2) design of a network of complicated cross inductive connections of major members of RP families; and (3) an analysis of the peculiar features of functioning of numerous internal reward factors.

Key words: anxiety, biologically active substances, depression, expert system, regulatory peptides, internal reward factor
