Synthesis and in vitro and in vivo characterization of highly beta1-selective beta-adrenoceptor partial agonists

beta-Adrenoceptor antagonists boast a 50-year use for symptomatic control in numerous cardiovascular diseases. One might expect highly selective antagonists are available for the human beta-adrenoceptor subtype involved in these diseases, yet few truly beta1-selective molecules exist. To address this clinical need, we re-evaluated LK 204-545 (1),(1) a selective beta1-adrenoceptor antagonist, and discovered it possessed significant partial agonism. Removal of 1’s aromatic nitrile afforded 19, a ligand with similar beta1-adrenoceptor selectivity and partial agonism (log KD of -7.75 and -5.15 as an antagonist of functional beta1- and beta2-mediated responses, respectively, and 34% of the maximal response of isoprenaline (beta1)). In vitro beta-adrenoceptor selectivity and partial agonism of 19 were mirrored in vivo. We designed analogues of 19 to improve affinity, selectivity, and partial agonism. Although partial agonism could not be fully attenuated, SAR suggests that an extended alkoxyalkoxy side chain, alongside substituents at the meta- or para-positions of the phenylurea, increases ligand affinity and beta1-selectivity.

Iron-Catalysed Remote C(sp3)?H Azidation of O-Acyl Oximes and N-Acyloxy Imidates Enabled by 1,5-Hydrogen Atom Transfer of Iminyl and Imidate Radicals: Synthesis of gamma-Azido Ketones and beta-Azido Alcohols

In the presence of a catalytic amount of iron(III) acetylacetonate [Fe(acac)3], the reaction of structurally diverse ketoxime esters with trimethylsilyl azide (TMSN3) afforded gamma-azido ketones in good to excellent yields. This unprecedented distal gamma-C(sp3)?H bond azidation reaction went through a sequence of reductive generation of an iminyl radical, 1,5-hydrogen atom transfer (1,5-HAT) and iron-mediated redox azido transfer to the translocated carbon radical. TMSN3 served not only as a nitrogen source to functionalise the unactivated C(sp3)?H bond, but also as a reductant to generate the catalytically active FeII species in situ. Based on the same principle, a novel beta-C(sp3)?H functionalisation of alcohols via N-acyloxy imidates was subsequently realised, leading, after hydrolysis of the resulting ester, to beta-azido alcohols, which are important building blocks in organic and medicinal chemistry.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 214894-89-0 is helpful to your research. Synthetic Route of 214894-89-0

Facile Access to Challenging ortho-Terphenyls via Merging Two Multi-Step Domino Reactions in One-Pot: A Joint Experimental/Theoretical Study

ortho-Terphenyls are of high interest for medicinal chemistry and materials science, but they are difficult to access. Herein, we demonstrate a straightforward and sustainable synthesis of highly functionalized ortho-terphenyls via joining an organocatalyzed two-step domino reaction (Knoevenagel/vinylogous Michael) with a DABCO/CuBr2 co-catalyzed three-step domino reaction (cyclization/tautomerization/aromatization) in a one-pot process. Overcoming necessity to isolate intermediate products leads to a reduction of energy, costs and waste for a broad scope of reactions. DFT calculations have been performed to investigate the thermodynamics of this one-pot process towards ortho-terphenyls and to study the reaction profile of the vinylogous Michael reaction under inclusion of solvent effects. Role of London dispersion forces in this transformation has been elucidated. It is shown that reaction kinetics and thermodynamics are slightly influenced by dispersion interactions. Furthermore, the addition of dispersion energy donors leads to small changes of reaction energies in some cases.

Structural requirements for factor Xa inhibition by 3-oxybenzamides with neutral P1 substituents: Combining X-ray crystallography, 3D-QSAR, and tailored scoring functions

The design, synthesis, and structure-activity relationship of 3-oxybenzamides as potent inhibitors of the coagulation protease factor Xa are described on the basis of X-ray structures, privileged structure motifs, and SAR information. A total of six X-ray structures of fXa/inhibitor complexes led us to identify the major protein-ligand interactions. The binding mode is characterized by a lipophilic dichlorophenyl substituent interacting with Tyr228 in the protease S1 pocket, while polar parts are accommodated in S4. This alignment in combination with docking allowed derivation of 3D-QSAR models and tailored scoring functions to rationalize biological affinity and provide guidelines for optimization. The resulting models showed good correlation coefficients and predictions of external test sets. Furthermore, they correspond to binding site topologies in terms of steric, electrostatic, and hydrophobic complementarity. Two approaches to derive tailored scoring functions combining binding site and ligand information led to predictive models with acceptable predictions of the external set. Good correlations to experimental affinities were obtained for both AFMoC (adaptation of fields for molecular comparison) and the novel TScore function. The SAR information from 3D-QSAR and tailored scoring functions agrees with all experimental data and provides guidelines and reasonable activity estimations for novel fXa inhibitors.

Photochemical Transformation of O-(beta-Arylethyl) Arylimidates into 2,4-Diaryl-5-iodoxazoles with 1,3-Diiodo-5,5-dimethylhydantoin

Treatment of O-(beta-arylethyl) arylimidates with 1,3-diiodo-5,5-dimethylhydantoin (DIH) under irradiation with a tungsten lamp in 1,2-dichloroethane gave the corresponding 2,4-diaryl-5-iodoxazoles and 2,4-diaryloxazoles in good to moderate yields, respectively, depending on the aryl group. It was proposed that the reactions proceeded through the formation of N-iodoimidates by the reaction of O-(beta-arylethyl) arylimidates with DIH, followed by the formation of iminyl radicals via homolytic N?I bond cleavage, the 1,5-H shift by the iminyl radicals, the C?I bond formation of the formed carbon-centered radicals with iodine, the nucleophilic cyclization by the imino groups to form 2,4-diaryloxazolines, the oxidation of the formed 2,4-diaryloxazolines to 2,4-diaryloxazoles, and the iodination of the formed 2,4-diaryloxazoles to 2,4-diaryl-5-iodoxazoles with DIH.
