Two isomeric ligands Htzpya and Hpytza (Htzpya≤3-(5-tetrazolyl)pyridine-1-acetic acid, Hpytza≤5-(3-pyridyl)tetrazole-2-acetic acid) have been selected to react with DyCl3·6H2O or PrCl3·6H2O under hydrothermal conditions, resulting in the formation of four new coordination compounds, mononuclear [Dy(tzpya)2(H2O)5]Cl·4H2O (1), dinuclear [Pr2(tzpya)2(H2O)12]Cl4·2H2O (2), and two one-dimensional polymers [Dy(pytza)2Cl(H2O)2]n (3) and [Pr(pytza)2Cl(H2O)2]n (4), whose structures are controlled by the different positions of the carboxylate group. These compounds were characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. Compounds 1-4 are self-assembled to form three-dimensional network structures by hydrogen bonding interactions. Furthermore, the luminescence properties were also investigated at room temperature in the solid state.

The present study describes the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-ylacetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, we identified a tetrazole scaffold that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, we evaluated the compounds in Tier 1 DMPK assays and have identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.
