Rhodium(III)/Amine Synergistically Catalyzed Enantioselective Alkylation of Aldehydes with alpha,beta-Unsaturated 2-Acyl Imidazoles

A synergistic catalysis combination of chiral-at-metal rhodium complex and amine catalyst was developed for enantioselective alkylation of aldehydes with alpha,beta-unsaturated 2-acyl imidazoles. The corresponding adducts were obtained in good yields with excellent enantioselectivities (up to 99% ee).

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.Recommanded Product: 137076-22-3, you can also check out more blogs about137076-22-3

Discovery and Optimization of 1-Phenoxy-2-aminoindanes as Potent, Selective, and Orally Bioavailable Inhibitors of the Na+/H+ Exchanger Type 3 (NHE3)

The design, synthesis, and structure-activity relationship of 1-phenoxy-2-aminoindanes as inhibitors of the Na+/H+ exchanger type 3 (NHE3) are described based on a hit from high-throughput screening (HTS). The chemical optimization resulted in the discovery of potent, selective, and orally bioavailable NHE3 inhibitors with 13d as best compound, showing high in vitro permeability and lacking CYP2D6 inhibition as main optimization parameters. Aligning 1-phenoxy-2-aminoindanes onto the X-ray structure of 13d then provided 3D-QSAR models for NHE3 inhibition capturing guidelines for optimization. These models showed good correlation coefficients and allowed for activity estimation. In silico ADMET models for Caco-2 permeability and CYP2D6 inhibition were also successfully applied for this series. Moreover, docking into the CYP2D6 X-ray structure provided a reliable alignment for 3D-QSAR models. Finally 13d, renamed as SAR197, was characterized in vitro and by in vivo pharmacokinetic (PK) and pharmacological studies to unveil its potential for reduction of obstructive sleep apneas.

Effective removal of Pb(II) using magnetic Co0.6Fe2.4O4 micro-particles as the adsorbent: Synthesis and study on the kinetic and thermodynamic behaviors for its adsorption

Magnetically separable adsorbent composed of Co0.6Fe2.4O4 micro-particles were successfully prepared by thermal decomposition of the Co0.6Fe2.4C2O4¡¤2H2O. The as-prepared samples were characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), X-ray energy dispersive spectroscopy (EDS). The specific surface area of the sample is determined to be 97.155m2g-1, with uniform pore size distribution centering at about 7.432nm. The as-obtained Co0.6Fe2.4O4 micro-particles exhibits ferromagnetic behavior at room temperature, which makes it magnetically separable under external magnetic field. The as-obtained magnetic Co0.6Fe2.4O4 micro-particles exhibits excellent adsorption capacity and high adsorption rate for the removal of Pb(II) in aqueous solution. The maximum adsorption capacity of Pb(II) is up to 80.32mgg-1 and 88% of the Pb(II) can be removed within the initial 30min of contact time. The effects of contact time, initial pH, ionic strength and temperature on the adsorption behavior of Pb(II) were systematically investigated. The kinetics of the adsorption process follows the pseudo-second-order model and is controlled by the film diffusion process. The equilibrium data can be fitted well using the Langmuir isotherm model, suggesting that the uptake of Pb(II) ions is a mono-layer adsorption process. Meanwhile, the mean free energy E calculated by D-R isotherm model demonstrates that the adsorption process is implemented via the chemical ion-exchange mechanism. The thermodynamic studies illustrate that the adsorption process is endothermic and spontaneous in nature.

A facile one-pot synthesis of 3-imidazolyl 1,2,4-triazoles and 1,2,4-oxa-diazolones

5-(5-Aminoimidazol-4-yl)-1,2,4-triazol-3-ones were obtained under mild experimental conditions from 5-amino-4-(N-ethoxycarbonyl) cyanoformimidoyl imidazoles and hydrazine in a rapid one-pot reaction. When hydroxylamine hydrochloride was used, in the presence of base, the corresponding 1,2,4-oxadiazol-5-ones were isolated. An equally fast reaction occurred when 5-amino-4-(N-acetyl/benzoyl) cyanoformimidoyl imidazoles were combined with hydrazine to give 5-(5-aminoimidazol-4-yl)-1,2,4-triazoles.

Multitarget-Directed Ligands Combining Cholinesterase and Monoamine Oxidase Inhibition with Histamine H3R Antagonism for Neurodegenerative Diseases

The therapy of complex neurodegenerative diseases requires the development of multitarget-directed drugs (MTDs). Novel indole derivatives with inhibitory activity towards acetyl/butyrylcholinesterases and monoamine oxidases A/B as well as the histamine H3 receptor (H3R) were obtained by optimization of the neuroprotectant ASS234 by incorporating generally accepted H3R pharmacophore motifs. These small-molecule hits demonstrated balanced activities at the targets, mostly in the nanomolar concentration range. Additional in vitro studies showed antioxidative neuroprotective effects as well as the ability to penetrate the blood?brain barrier. With this promising in vitro profile, contilisant (at 1 mg kg?1 i.p.) also significantly improved lipopolysaccharide-induced cognitive deficits.

Sulfide Analogues of Flupirtine and Retigabine with Nanomolar KV7.2/KV7.3 Channel Opening Activity

The potassium channel openers flupirtine and retigabine have proven to be valuable analgesics or antiepileptics. Their recent withdrawal due to occasional hepatotoxicity and tissue discoloration, respectively, leaves a therapeutic niche unfilled. Metabolic oxidation of both drugs gives rise to the formation of electrophilic quinones. These elusive, highly reactive metabolites may induce liver injury in the case of flupirtine and blue tissue discoloration after prolonged intake of retigabine. We examined which structural features can be altered to avoid the detrimental oxidation of the aromatic ring and shift oxidation toward the formation of more benign metabolites. Structure?activity relationship studies were performed to evaluate the KV7.2/3 channel opening activity of 45 derivatives. Sulfide analogues were identified that are devoid of the risk of quinone formation, but possess potent KV7.2/3 opening activity. For example, flupirtine analogue 3-(3,5-difluorophenyl)-N-(6-(isobutylthio)-2-(pyrrolidin-1-yl)pyridin-3-yl)propanamide (48) has 100-fold enhanced activity (EC50=1.4 nm), a vastly improved toxicity/activity ratio, and the same efficacy as retigabine in vitro.

Covalent docking modelling-based discovery of tripeptidyl epoxyketone proteasome inhibitors composed of aliphatic-heterocycles

The potential of specific proteasome inhibitors to act as anti-cancer agents has attracted intensive investigations. The proteasome can be covalently inhibited by epoxyketone derivatives via a two-step reaction. Several computational approaches have been developed to mimic the covalent binding event. Compound 1 composed of a six-membered heterocyclic ring was designed by using covalent docking. With a possible different binding mode from the clinical compound Carfilzomib, it occupied the S5 pocket of 20S proteasome and showed favorable inhibitory activity. Subsequently optimization and evaluation were taken place. Among these compounds, 11h demonstrated extraordinary in vitro inhibitory activity and selectivity, and good in vivo proteasome inhibitory activity, a favorable pharmacokinetic profile and xenograft tumor inhibition. The possible binding pattern of compound 11h against proteasome was further fully explored via calculations, providing a theoretical basis for finding potent proteasome inhibitors.

4-Hydroxy-1,2,3-triazole moiety as bioisostere of the carboxylic acid function: a novel scaffold to probe the orthosteric gamma-aminobutyric acid receptor binding site

The correct application of bio(iso)steric replacement, a potent tool for the design of optimized compounds, requires the continuous development of new isosters able to respond to specific target requirements. Among carboxylic acid isosters, as the hydroxylated pentatomic heterocyclic systems, the hydroxy-1,2,3-triazole represents one of the most versatile but less investigated. With the purpose to enlarge its bioisosteric application, we report the results of a study devoted to obtain potential biomimetics of the gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system (CNS). A series of N1- and N2- functionalized 4-hydroxy-1,2,3-triazole analogues of the previous reported GABAAR ligands, including muscimol, 4-PIOL, and 4-PHP has been synthesized and characterized pharmacologically. Furthermore, this study led to development of straightforward chemical strategies directed to decorate the hydroxytriazole core scaffold, opening for further elaborative studies based on this system. The unsubstituted N1- and N2-piperidin-4-yl-4-hydroxy-1,2,3-triazole analogues (3a, 4a) of 4-PIOL and 4-PHP showed weak affinity (high to medium micromolar range), whereas substituting the 5-position of the triazole core with a 2-naphthylmethyl or 3,3-diphenylpropyl led to binding affinities in the low micromolar range. Based on electrostatic analysis and docking studies using a alpha1beta2gamma2 GABAAR homology model we were able to rationalize the observed divergence in SAR for the series of N1- and N2- piperidin-4-yl-4-hydroxy-1,2,3-triazole analogues, offering more detailed insight into the orthosteric GABAAR binding site.
