  1,3-Dioxolane-based ligands incorporating a lactam or imide moiety: Structure–affinity/activity relationship at α1-adrenoceptor subtypes and at 5-HT1A receptors

  摘要：

  A series of 1,3-dioxolane-based compounds incorporating a lactam (2-4) or imide (5-7) moiety was synthesized and the pharmacological profile at alpha(1)-adrenoceptor subtypes and 5-HT1A receptor was assessed through binding and functional experiments. Starting from the 2,2-diphenyl-1,3-dioxolane derivative 1, previously shown to be a selective alpha(1a(A))/alpha(1d(D))-adrenoceptor subtype antagonist, over alpha(1b(B)) subtype and 5-HT1A receptor, and replacing one phenyl ring with lactam or imide moiety a reduction of alpha(1)/5-H-1A selectivity is observed, mainly due to the increase in 5-H-1A affinity. In functional experiments lactam derivatives seems to favour 5-HT1A receptor antagonism (pKb = 7.20-7.80) and alpha(1B)-adrenoceptor antagonist selectivity (alpha(1B)/alpha(1A) and alpha(1B)/alpha(1D) of about 10-fold). The most interesting of the various imide derivatives is compound 7t, which is a selective alpha(1D)-adrenoceptor antagonist (pKb = 8.1 and alpha(1D)/alpha(1A) and alpha(1D)/alpha(1B) selectivity ratios of 16 and 11 respectively) whereas at 5-HT1A receptor it is a potent partial agonist (pD2 = 7.98, E-max = 60%).]. Given that as and trans diastereomer pairs for 2-7 are possible, a computational strategy based on molecular docking studies was used to elucidate the atomic details of the 5-HT1A/agonist and 5-HT1A/antagonist interaction.
