A novel bonding mode of a deprotonated synanti 2,2?-dipyridylamine ligand to dimethyl aluminium and dimethyl gallium. Synthesis, characterization and X-ray crystal structure of Me2Ga(DPA) (DPA = 2,2?-dipyridylamine)

The reaction of 2,2?-dipyridylamine with R3M (R = CH3, M = Ga, Al) gave the Lewis acid-base adducts Me2Ga(dpa) and Me2Al(dpa) (where dpa is 2,2?dipyridylamide). X-ray analysis showed an unusual structure of dpa- in the formation of a new anti-anti complex Me2Ga(dpa) with extremely short bond distances Ga-N(1) [1.976(3) A] and Ga-N(2) [1.978(3) A]. The gallium atom is in a tetrahedral environment, coordinated to the deprotonated chelating ligand and two methyl groups. The bond distances N(3)-C(5) [1.345(4) A] and N(3)-C(6) [1.347(4) A] are almost identical. The bond angle N(1)-Ga-N(2) [92.0(1)] is 17 smaller than, and C(12)-Ga-N(1) [109.5(2)] is almost equal to, normal tetrahedral angles. These adducts are much less air- and moisture-sensitive than the metal trialkyl. The compounds were characterized by elemental analysis, NMR and mass spectroscopy. The conformation of the dipyridylamide ligand in the bidentate chelate complex is significantly different from that observed for other dipyridylamine complexes. Copyright

Functionalized 6-(piperidin-1-yl)-8,9-diphenyl purines as inverse agonists of the CB1 receptor ? SAR efforts towards selectivity and peripheralization

Antagonists of type 1 cannabinoid receptors (CB1) may be useful in treating diabetes, hepatic disorders, and fibrosis. Otenabant (1) is a potent and selective CB1 inverse agonist that was under investigation as an anti-obesity agent, but its development was halted once adverse effects associated with another marketed inverse agonist rimonabant (2) became known. Non-tissue selective antagonists of CB1 that have high levels of brain penetration produce adverse effects in a small subset of patients including anxiety, depression and suicidal ideation. Currently, efforts are underway to produce compounds that have limited brain penetration. In this report, novel analogs of 1 are explored to develop and test strategies for peripheralization. The piperidine of 1 is studied as a linker, which is functionalized with alkyl, heteroalkyl, aryl and heteroaryl groups using a connector in the form of an amine, amide, sulfonamide, sulfamide, carbamate, oxime, amidine, or guanidine. We also report more polar replacements for the 4-chlorophenyl group in the 9-position of the purine core, which improve calculated physical properties of the molecules. These studies resulted in compounds such as 75 that are potent inverse agonists of hCB1 with exceptional selectivity for hCB1 over hCB2. SAR studies revealed ways to adjust physical properties to limit brain exposure.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 2081-44-9, you can also check out more blogs about2081-44-9

The structure and magnetic properties of a 3D pillared-layer polymer and two helical chains constructed from flexible ligands

Three novel coordination polymers of CoII and CuII with flexible ligands, namely [Co(oba)(dpa)]n (1), [Cu(oba)(dpa)]n (2) and [Cu(oba)(bpy)1/2]n (3) [H2oba = 4,4?-oxybis(benzoic acid), dpa = 2,2?-dipyridylamine, bpy = 4,4?-bipyridine] were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analyses, elemental analysis and IR spectroscopy.

These chains are further assembled into 3D supramolecular edifice via aromatic pi-pi stacking interactions and intermolecular hydrogen bonding. The CuII ions in complex 3 are linked by the carboxylate groups oba to form an eight-membered ring chains, the connectivity between the corner-shared eight-membered ring chains are further bridged by the bent oba ligands to produce 2D helical layer containing the right-handed helical chains. Furthermore, the adjacent helical layers are connected by bpy pillars to form a novel 3D framework with an unprecedented topology of (315¡¤420¡¤58¡¤62).

Electrophoretically mediated microscale reaction of glycosidases: Kinetic analysis of some glycosidases at the nanoliter scale

Capillary electrophoresis (CE) is one of the extremely important analytical techniques known for its high sensitivity and resolution. We have investigated electrophoretically mediated microanalysis (EMMA) for the assay of some native glycosidases. Under optimized conditions, the enzymatic reactions of alpha-glucosidase, beta-galactosidase and beta-N-acetylglucosaminidase were carried out, and the Michaelis constants were obtained. The current method may have advantages over traditional assay methods, especially in terms of the amount of enzyme and substrate required for a reaction.

Aqueous dehydration, hydrogenation, and hydrodeoxygenation reactions of bio-based mucic acid over ni, nimo, pt, rh, and ru on neutral or acidic catalyst supports

Hydrotreatment of mucic acid (also known as galactaric acid, an glucaric acid enantiomer), one of the most promising bio-based platform chemicals, was systematically investigated in aqueous media over alumina, silica, or carbon-supported transition (nickel and nickel-molybdenum) or noble (platinum, ruthenium and rhodium) metals. Mucic acid was only converted into mucic-1,4-lactone under non-catalytic reaction conditions in N2 atmosphere, while the 5 MPa gaseous H2 addition triggers hydrogenation in the bulk phase, resulting in formation of galacturonic and galactonic acid. However, dehydroxylation, hydrogenation, decarbonylation, decarboxylation, and cyclization occurred during catalytic hydrotreatment, forming various partially and completely deoxygenated products with a chain length of 3-6 C atoms. Characterization results of tested catalysts were correlated with their activity and selectivity. Insufficient pore diameter of microporous supports completely hindered the mass transfer of reactants to the active sites, resulting in negligible conversion of mucic acid. A comprehensive reaction pathway network was proposed and several industrially interesting compounds were formed, including levulinic acid, furoic acid, and adipic acid. However, selectivity towards adipic acid, a bio-based nylon 6,6 precursor, was low (up to 5 mol%) in aqueous media and elevated temperatures.
