  Structure–activity relationship studies with (±)-nantenine derivatives for α1-adrenoceptor antagonist activity

  摘要：

  A series of (+/-)-nantenine derivatives of the natural aporphine alkaloids was synthesized and examined for a blocking action on a, adrenoceptors in rat aorta and A10-cells. The potency of these derivatives was compared with that of an aporphine-related compounds (+)boldine, an alpha(1)-adrenoceptor antagonist. Among nine (+/-)-nantenine derivatives having different substituents at N-6, C-1, or C-4 of the aporphine skeleton, (+/-)-domesticine had the most powerful ot alpha(1) -adrenoceptor-blocking action. The order of pA(2) values was (+/-)-domesticine (8.06 +/- 0.06)>(+/-)-nordomesticine (7.34 +/- 0.03)>(+/-)-nantenine(7.03 +/- 0.03)>(+)-boldine(6.91 +/- 0.02)> other derivatives. Study of the structure -activity relationships showed that the replacement of a methoxy moiety at C-1 position of (+/-)-nantenine with a hydroxyl group increased affinity for the receptor. In contrast, replacement of a methyl group with a hydrogen atom or an ethyl group at N-6 position in the (+/-)-nantenine structure decreased affinity for the receptor. These results suggest that a hydroxyl group at the C-1 position and a methyl group at the N-6 position in the (+/-)-nantenine structure are essential for the enhancement of affinity for the alpha(1)-adrenoceptor.

• Affinity of aporphines for the human 5-HT2A receptor: Insights from homology modeling and molecular docking studies

  Analogs of nantenine were docked into a modeled structure of the human 5-HT2A receptor using ICM Pro, GLIDE, and GOLD docking methods. The resultant docking scores were used to correlate with observed in vitro apparent affinity (K-e) data. The GOLD docking algorithm when used with a homology model of 5-HT2A, based on a bovine rhodopsin template and built by the program MODELLER, gives results which are most in agreement with the in vitro results. Further analysis of the docking poses among members of a C1 alkyl series of nantenine analogs, indicate that they bind to the receptor in a similar orientation, but differently than nantenine. Besides an important interaction between the protonated nitrogen of the C1 alkyl analogs and residue Asp155, we identified Ser242, Phe234, and Gly238 as key residues responsible for the affinity of these compounds for the 5-HT2A receptor. Specifically, the ability of some of these analogs to establish a H-bond with Ser242 and hydrophobic interactions with Phe234 and Gly238 appears to explain their enhanced affinity as compared to nantenine.
