The title compound, [Ir(C10H5F2N2)2(C5H7O2)], has a distorted octa-hedral coordination geometry around the Ir(III) atom, retaining the cis-C,C/trans-N,N chelate disposition in two 2,6-di-fluoro-3-(pyridin-2-yl-κN)pyridin-4-yl ligands which are nearly mutually perpendicular [dihedral angle = 82.75 (15)°]. The mol-ecular structure is stabilized by weak C-H⋯O and C-H⋯F hydrogen-bond inter-actions....

Δ(9)-Tetrahydrocannbinol (THC), the primary active constituent of Cannabis sativa, has long been known to reduce opioid withdrawal symptoms. Although THC produces most of its pharmacological actions through the activation of CB(1) and CB(2) cannabinoid receptors, the role these receptors play in reducing the variety of opioid withdrawal symptoms remains unknown. The endogenous cannabinoids, N-a...

Copper(II) complexes of benzimidazole are known to exhibit biological activity that makes them of inter-est for chemotherapeutic and other pharmaceutical uses. The complex bis-(acetato-κO){5,6-dimethyl-2-(pyridin-2-yl)-1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-κ2N2,N3}copper(II), has been prepared. The absorption spectrum has features attributed to intra-ligand and ligand-field transitions and...

pathogenic infections and inflammation are very common ailments humans suffer. upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. in line with these developments the synthesis of n-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4h-1...

Use of single-handed dynamic helical macromolecules as nucleophilic catalysts in asymmetric Steglich-type O-to-C aryloxycarbonyl rearrangement 3-substituted indol-2-yl aryl carbonates is demonstrated. Among several poly(quinoxaline-2,3-diyl) copolymers (PQXap) bearing achiral 4-aminopyridin-3-yl groups at the 5-position quinoxaline rings, PQXmdpp and PQXapy, containing N-methylpyrrolidine-fused...

Compounds with excellent receptor engagement displaying ?2-AR antagonist activity are useful not only for therapeutic purposes (e.g. antidepressants), but also to help in the crystallization of this particular GPCR. Therefore, based on our broad experience topic, we have prepared eighteen di-aryl (phenyl and/or pyridin-2-yl) mono- or di-substituted guanidines and 2-aminoimidazolines. The vitro ...

Single crystals of the title compound, C19H16N2O4, were obtained under hydro-thermal conditions by an unintended recrystallization of the employed microcrystalline starting material. The [(pyridin-4-yl)meth-oxy]benzoic acid unit is nearly planar, with a maximum deviation from the least-squares plane of 0.194 (2) Å. This plane is inclined by 35.82 (6)° to that defined by the second (pyridin-4-yl...

The asymmetric unit of the title compound, [Co(C(9)H(7)O(4))(2)(C(12)H(10)N(2))(2)(H(2)O)(2)], consists of one Co(2+) ion, one mono-deprotonated 2-(4-carboxyl-atophen-yl)acetate carboxylic acid, one 1,2-bis-(pyridin-4-yl)ethane mol-ecule and one water mol-ecule. The Co(II) atom is situated on a crystallographic center of inversion and is octa-hedrally coordinated by two O atoms from two anions,...
