Atom-Economic Synthesis of Fully Substituted 2-Aminopyrroles via Gold-Catalyzed Formal [3+2] Cycloaddition between Ynamides and Isoxazoles

A concise and flexible synthesis of fully substituted 2-aminopyrroles via gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles has been developed. Under mild reaction conditions, various 2-aminopyrrole derivatives were obtained in good to excellent yields, thus providing an efficient and atom-economic way for the construction of fully substituted 2-aminopyrroles. It was all very formal: A novel gold-catalyzed formal [3+2] cycloaddition between ynamides and isoxazoles has been developed, allowing the concise and flexible synthesis of fully substituted 2-aminopyrroles. Importantly, this strategy provides new mechanistic insights and offers an atom-economic way for the construction of fully substituted 2-aminopyrroles.

Synthesis and anticancer activity of CDDO and CDDO-me, two derivatives of natural triterpenoids

Triterpenoids are natural compounds synthesized by plants through cyclization of squalene, known for their weak anti-inflammatory activity. 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO), and its C28 modified derivative, methyl-ester (CDDO-Me, also known as bardoxolone methyl), are two synthetic derivatives of oleanolic acid, synthesized more than 20 years ago, in an attempt to enhance the anti-inflammatory behavior of the natural compound. These molecules have been extensively investigated for their strong ability to exert antiproliferative, antiangiogenic, and antimetastatic activities, and to induce apoptosis and differentiation in cancer cells. Here, we discuss the chemical properties of natural triterpenoids, the pathways of synthesis and the biological effects of CDDO and its derivative CDDO-Me. At nanomolar doses, CDDO and CDDO-Me have been shown to protect cells and tissues from oxidative stress by increasing the transcriptional activity of the nuclear factor (erythroid-derived 2)-like 2 (Nrf2). At doses higher than 100 nM, CDDO and CDDO-Me are able to modulate the differentiation of a variety of cell types, both tumor cell lines or primary culture cell, while at micromolar doses these compounds exert an anticancer effect in multiple manners; by inducing extrinsic or intrinsic apoptotic pathways, or autophagic cell death, by inhibiting telomerase activity, by disrupting mitochondrial functions through Lon protease inhibition, and by blocking the deubiquitylating enzyme USP7. CDDO-Me demonstrated its efficacy as anticancer drugs in different mouse models, and versus several types of cancer. Several clinical trials have been started in humans for evaluating CDDO-Me efficacy as anticancer and anti-inflammatory drug; despite promising results, significant increase in heart failure events represented an obstacle for the clinical use of CDDO-Me.

In silico exploration of aryl sulfonamide analogs as voltage-gated sodium channel 1.7 inhibitors by using 3D-QSAR, molecular docking study, and molecular dynamics simulations

It has been demonstrated by human genetics that the voltage-gated sodium channel Nav1.7 is currently a promising target for the treatment of pain. In this research, we performed molecular simulation works on a series of classic aryl sulfonamide Nav1.7 inhibitors using three-dimensional quantitative structure-activity relationships (3D-QSAR), molecular docking and molecular dynamics (MD) simulations for the first time to explore the correlation between their structures and activities. The results of the relevant statistical parameters of comparative molecular field analyses (CoMFA) and comparative molecular similarity indices analyses (CoMSIA) had been verified to be reasonable, and the deep relationship between the structures and activities of these inhibitors was obtained by analyzing the contour maps. The generated 3D-QSAR model showed a good predictive ability and provided valuable clues for the rational modification of molecules. The interactions between compounds and proteins were modeled by molecular docking studies. Finally, accuracy of the docking results and stability of the complexes were verified by 100 ns MD simulations. Detailed information on the key residues at the binding site and the types of interactions they participate in involved was obtained. The van der Waals energy contributed the most in the molecular binding process according to the calculation of binding free energy. All research results provided a good basis for further research on novel and effective Nav1.7 inhibitors.

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.category: Isoxazoles, you can also check out more blogs about288-14-2

C1-Galactopyranosyl Heterocycle Structure Guides Selectivity: Triazoles Prefer Galectin-1 and Oxazoles Prefer Galectin-3

Galectins are carbohydrate-recognizing proteins involved in many different pathological processes, including cancer and immune-related disorders. Inhibitors of galectins have evolved from natural oligosaccharides toward more drug-like truncated galactoside scaffolds that only retain key specific interactions of the galactose scaffolds with the galectin carbohydrate recognition domains. In this context, C1-galactosides are attractive and stable scaffolds, and this work reports that the synthesis of novel C1-galactopyranosyl heteroaryl derivatives as galectin inhibitors, in which galectin selectivity is governed by the composition of the heterocycle and affinity, is driven by the structure of the aryl substituent to give compounds selective for either galectin-1 or galectin-3. The affinities are close to or better than those of lactose and other natural galectin-binding disaccharides, selectivities induced by the C1-heteroaryl groups are superior to lactose, and compound hydrolytic stabilities and drug-like properties are potentially better than those of natural saccharides. Hence, C1-galactopyranosyl heteroaryls constitute a class of promising starting scaffolds for galectin inhibition, in which a natural ligand pyranose has been replaced by more than fivefold selectivity-inducing heteroaryl rings leading to affinities of 90 muM toward galectin-3 for a C1-galactopyranosyl naphthyloxazole and 170 muM toward galectin-1 for a C1-galactopyranosyl 2-fluorophenyltriazole.

Selective access to dipyrazolo-fused pyridines: Via formal [3 + 2 + 1] heteroannulation of methyl ketones with pyrazol-5-amines

A fascinating new form of the Hantzsch reaction with methyl ketones and pyrazol-5-amines for the selective synthesis of dipyrazolo-fused pyridines has been discovered. This special [3 + 2 + 1] heteroannulation was accomplished via the domino generation of two C-C bonds and one C-N bond. Preliminary mechanistic studies indicated that the I2/DMSO system realized the oxidative carbonylation of Csp3-H of methyl ketones, while Cu(OTf)2 acted as a relay reagent to accelerate this transformation.

Iron-Catalyzed Transfer Hydrogenation in Aged N-Methyl-2-pyrrolidone: Reductive Ring-Opening of 3,5-Disubstituted Isoxazoles and Isoxazolines

3,5-Disubstituted isoxazoles and isoxazolines undergo an iron-catalyzed reductive ring-opening in aged N-methyl-2-pyrrolidone (NMP). 5-Hydroxy-N-methyl-2-pyrrolidone generated in situ via a simple activation of commercial NMP acts as the hydrogen donor in the iron-catalyzed transfer hydrogenation reaction. It is the first example employing a combination of an iron catalyst and 5-hydroxy-N-methyl-2-pyrrolidone as reducing agents in a transfer hydrogenation reaction. The protocol is highly efficient for the synthesis of beta-enaminones and 1,3-diketones, providing a versatile route for the preparation of these 1,3-difunctional compounds bearing diversified substitution patterns.
