Heterogeneously catalysed carbonylative coupling reactions such as aminocarbonylation and Suzuki-carbonylation are reported using Pd nanoparticles supported on ZIF-8 for efficient and environmentally attractive synthesis of Weinreb amides and ketones from aryl bromides or iodides. The catalyst is air stable, offers high activity with very low palladium leaching and is recyclable. The presence of a phosphine ligand was required when aryl bromides were used as substrates, while no ligand was necessary when aryl iodides were used. the Partner Organisations 2014.

experimental part, p. 7869 - 7873 (2011/01/12)
A series of compounds was designed as dual inhibitors of the H3 receptor and the norepinephrine transporter. Compound 5 (rNET Ki = 14 nM; rH3R Ki = 37 nM) was found to be efficacious in a rat model of osteoarthritic pain.

A novel class of biphenyl analogues containing a benzoic acid moiety based on lead compound 8i have been identified as potent and selective human β3 adrenergic receptor (β3-AR) agonists with good oral bioavailability and long plasma half-life. After further substituent effects were investigated at the terminal phenyl ring of lead compound 8i, we have discovered that more lipophilic substitution at the R position improved potency and selectivity. As a result of these studies, 10a and 10e were identified as the leading candidates with the best balance of potency, selectivity, and pharmacokinetic profiles. In addition, compounds 10a and 10e were evaluated to be efficacious for a carbachol-induced increase of intravesical pressure, such as an overactive bladder model in anesthetized dogs. This represents the first demonstrated result dealing with β3- AR agonists.
4-(2-[2-(2(R)-Methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile and related 2-aminoethylbenzofuran H3 receptor antagonists potently enhance cognition and attention

H3 receptor antagonists based on a 2-aminoethylbenzofuran skeleton have been discovered, which are potent in vitro at human and rat H 3 receptors, with Ki values of 0.1-5.8 nM. Analogues were discovered with potent (0.01-1 mg/kg) cognition and attention enhancing properties in animal models. One compound in particular, 4-(2-[2-(2(R)- methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile (ABT-239), combined potent and selective H3 receptor antagonism and excellent pharmacokinetic and metabolic properties across species, with full efficacy in two behavioral models: a five-trial inhibitory avoidance acquisition model in rat pups at 0.1 mg/kg and a social recognition memory model in adult rats at 0.01 mg/kg. Furthermore, this compound did not stimulate locomotor activity and showed high selectivity for the induction of behavioral efficacy versus central nervous system based side effects. The potency and selectivity of this compound and of analogues from this class support the potential of H3 receptor antagonists for the treatment of cognitive dysfunction.

SAR studies for novel non-imidazole containing H3 receptor antagonists with high potency and selectivity for rat H3 receptors are described. A high throughput screening lead, A-923, was further elaborated in a systematic manner to clarify a pharmacophore for this class of aryloxyalkyl piperazine based compounds.
