The title compounds were synthesized by replacing the thiophene moiety of A-86929(2a) with variously substituted pyridines. Dopamine D-1 and D-2 binding and adenylate cyclase assays indicate that 4,6-diaza compounds 15 are potent and selective full D1 agonists when R1 is H or a small substituent and R2=H, with D1 binding affinity and adenylate cyclase functional potency equivalent to that of A-86929(2a).
One-pot homo- and cross-coupling of diazanaphthalenes via C-H substitution: Synthesis of Bis- and Tris-diazanaphthalenes
Ucar, Sefa,Dastan, Arif
supporting information, p. 4013 - 4022 (2020/09/21)
The transition metal-free coupling reactions of unactivated diazanaphthalenes were studied using only lithium tetramethylpiperidine (LiTMP) reagent. Symmetrical and nonsymmetrical bis-diazanaphthalenes were synthesized in moderate to high yield by homo- and cross-coupling of related monomers. In addition, the single-step synthesis of diquinoxalino [2,3-a: 2', 3'c] phenazine and 2,2': 3', 2″ - terquinoxaline using the appropriate equivalent amount of LiTMP was performed. The products were characterized by means of NMR spectroscopy and HRMS spectrometry.

Synthesis and σ receptor affinity of regioisomeric spirocyclic furopyridines
Miyata, Kengo,Schepmann, Dirk,Wünsch, Bernhard
, p. 709 - 716 (2014/07/22)
In order to investigate systematically the effect of the position of the pyridine N-atom on the σ1 receptor affinity four regioisomeric furopyridines 2a-d were synthesized and pharmacologically evaluated. The key steps of the synthesis comprise bromine/lithium exchange at regioisomeric bromopyridinecarbaldehyde acetals 7a-d, subsequent addition to 1-benzylpiperidin-4-one and cyclization. The regioisomeric acetals 7a-d were obtained either by o-metalation of bromopyridines 5b and 5c or by oxidation of bromopicolines 3a and 3d. In radioligand binding studies the regioisomeric furopyridines 2a-d showed 7- to 12-fold lower σ1 affinity than the benzofuran analog 1. The reduced σ1 affinity of the furopyridines 2a-d is explained with the reduced electron density of the pyridine ring. Since the four regioisomeric furopyridines show almost the same σ1 affinity (Ki = 4.9-10 nM), a directed interaction of the pyridine N-atom with the receptor protein can be excluded.

Given its role in the mediation of energy and glucose homeostasis, the G-protein-coupled bile acid receptor1 (TGR5) is considered a potential target for the treatment of type2 diabetes mellitus and other metabolic disorders. By thorough analysis of diverse structures of published TGR5 agonists, a hypothetical ligand-based pharmacophore model was built, and a new class of potent TGR5 agonists, based on the novel 3,4,5-trisubstituted 4,5-dihydro-1,2,4-oxadiazole core, was discovered by rational design. Three distinct synthetic methods for constructing 4,5-dihydro-1,2,4-oxadiazoles and extensive structure-activity relationship studies are reported herein. Compound (R)-54n, the structure of which was determined by single-crystal X-ray diffraction and quantum chemical solid-state TDDFT-ECD calculations, showed the best potency, with an EC50 value of 1.4nM toward hTGR5. Its favorable properties invitro warrant further investigation.

Synthesis of 1-phenyl- and 1-pyridyl-3-pyridoazepines by reductive cyclization of diarylacetonitriles

scheme or table, p. 3653 - 3658 (2009/09/08)
Several pyrido[2,3-d]azepines and pyrido[3,4-d]azepines, novel aza analogs of the pharmacologically relevant 1-aryl-3-benzazepines, were synthesized by assembling the azepine ring by reductive cyclization of (2-methoxyvinyl)pyridinyl(aryl)acetonitrile derivatives, which were easily derived from contiguously substituted bromo(2-methoxyvinyl)pyridines and the corresponding arylacetonitriles.
