This chapter gives a summary of the book in the form of list of rules and propositions. Reading the summary, the reader can easily determine how much the book matter is fitted to her interests. All rules and propositions relate to the development of novel medicinal drugs selectively acting on neuroreceptors. The rules are derived from the two main concepts: 1) The principal problem in molecular recognition research lay with elucidation of mechanisms protecting medicinal drugs from non-specific binding in an organism. 2) Formation of a drug complex with the specific receptor is the final step of molecular recognition process.
