Abstract

Bz BZ H activity between 11 and 24 corresponds to a 1.68 kcal/mol increase in binding energy, which may support a specific hydrophobic interaction between the aromatic ring and the receptor protein. 6 Separation of the carboxamide moiety from the piperidine ring by alkyl or alkoxyalkyl bridges of varying lengths (26-30) had only minor influence on a,- adrenoceptor activity.
