The S_RN1 reaction has been used as a powerful tool for the synthesis of heterocycles, and only a few studies about photoinduced intramol. cyclization to generate a new C-O bond by a radical pathway have been reported. This work introduces two strategies for the synthesis of substituted dibenzofurans by electron transfer (eT) reactions. The first one is a three-step process that comprises bromination of o-arylphenols, Suzuki-Miyaura cross-coupling and photoinduced cyclization in order to obtain the above-mentioned products. The second one is a metal-free procedure and does not require any photocatalyst. Different solvents were tested, and the yields ranged from low to moderate. A comparison was established between both methodologies, showing that the second one is the most suitable for the synthesis of dibenzofurans.

Presa, Andreu published the artcilePhotoswitching the Cytotoxic Properties of Platinum(II) Compounds, Formula: C15H14Cl2S2, the publication is Angewandte Chemie, International Edition (2015), 54(15), 4561-4565, database is CAplus and MEDLINE.

The photoactivation of potential anticancer metal complexes is a hot topic of current research as it may lead to the development of more selective drugs. Photoactivated chemotherapy (PACT) with coordination compounds is usually based on a (photo)chem. reaction taking place at the metal center. Herein, a new strategy is exploited that consists of “photomodifying” a ligand coordinated to metal ions. Platinum(II) complexes from photoswitchable 1,2-dithienylethene-containing ligands have been prepared, which exhibit two interconvertible photoisomeric forms that present distinct DNA-interacting properties and cytotoxic behaviors.

Ranjitkar, Pratistha published the artcileAffinity reagents that target a specific inactive form of protein kinases, SDS of cas: 6313-54-8, the publication is Chemistry & Biology (Cambridge, MA, United States) (2010), 17(2), 195-206, database is CAplus and MEDLINE.

A number of small-mol. inhibitors have been developed that target the catalytic domains of protein kinases that are not in an active conformation. An inactive form that has been observed in several kinases is the DFG-out conformation. This conformation is characterized by an almost 180° rotation of the conserved Asp-Phe-Gly (DFG) motif in the ATP-binding cleft relative to the active form. However, the sequence and structural determinants that allow a kinase to stably adopt the DFG-out conformation are not known. Here, we characterize a series of inhibitors based on a general pharmacophore for this inactive form. We demonstrate that modified versions of these inhibitors can be used to study the thermodn. and kinetics of ligand binding to DFG-out-adopting kinases and for enriching these kinases from complex protein mixtures

Deltour, G. published the artcileDetermination of carnitine in biologic media, HPLC of Formula: 6249-56-5, the publication is Clinica Chimica Acta (1960), 181-5, database is CAplus and MEDLINE.

Carnitine, after extraction by appropriate solvents or liberation from biol. materials by acid hydrolysis, is separated electrophoretically. Separation is carried out on Whatman 3 MM paper at 400 v. by means of buffer prepared by adding pyridine to 0.3M AcOH to give a final pH of 4.1. Position of the carnitine spot is located with I vapor; the spot is cut out and eluted with HCl-EtOH, and carnitine is estimated by the method of Friedman (CA 52, 12978a) in which the ethyl ester is complexed in alk. medium with bromophenol blue. The procedure gives an error of the order of 10%. Application of the method to several betaines and the results are described.

As part of a program to develop a small mol. inhibitor of LIMK, a series of aminothiazole inhibitors were discovered by high throughput screening. Scaffold hopping and subsequent SAR directed development led to a series of low nanomolar inhibitors of LIMK1 and LIMK2 that also inhibited the direct biomarker p-cofilin in cells and inhibited the invasion of MDA MB-231-luc cells in a matrigel inverse invasion assay.

Yuen, Tsz Ying published the artcileSynthesis of chiral alkenyl cyclopropane amino acids for incorporation into stapled peptides, Quality Control of 5034-06-0, the publication is Journal of Organic Chemistry (2020), 85(3), 1556-1566, database is CAplus and MEDLINE.

α,α’-Disubstituted amino acids serve as important non-proteinogenic amino acids in the construction of stabilized helical peptides. To expand the repertoire of α,α’-disubstituted amino acids, chiral alkenyl-containing cyclopropane amino acids were synthesized via a two-step olefination and cyclopropanation procedure. Herein, we report the first example of the use of alkenyl cyclopropane building blocks to constrain MDM2-targeting helical peptides. The increased potency and efficacy associated with C-terminal cyclopropane substitution is postulated to be driven by a combined effect of net hydrophobicity and enhanced protein association rates.

Guin, Avishek published the artcileTransition-Metal-Free C2-Functionalization of Pyridines through Aryne Three-Component Coupling, Product Details of C8H4ClF3O, the publication is Chemistry – A European Journal (2021), 27(55), 13864-13869, database is CAplus and MEDLINE.

The direct C2-functionalization of pyridines I (R = H, Me, Cl, pyrrolidin-1-yl, etc.) through a transition-metal-free protocol by using arynes 2-Si(CH₃)₃-3-R¹-4-R²-5-R³-6-R⁴C₆OS(O)₂CF₃ (R¹ = H, Me, OMe; R² = H, Me, F, Cl; R¹R² = -(CH₂)₄-, -CH=CH-CH=CH-; R³ = H, Me, F; R²R³ = -OCH₂O-, -(CH₂)₂-, -CH=CH-CH=CH-; R⁴ = H, Me) multicomponent coupling is demonstrated. The reaction allowed a broad-scope synthesis of C2-substituted pyridine derivatives bearing the -CF₃ group II in good yields with α,α,α-trifluoroacetophenones ArC(O)CF₃ (Ar = Ph, pyren-1-yl, 1-benzothiophen-3-yl, etc.) as the third component. Activated keto esters could also be employed as the third component in this formal 1,2-di(hetero)arylation of ketones. Performing the reaction under dilute conditions inhibited the competing pyridine-aryne polymerization pathway. Nucleophilic attack by the initially generated pyridylidene intermediate on the carbonyl followed by an S_NAr process resembling the Smiles rearrangement affords the desired products.

Onder, Seda published the artcileThe kinetics of inhibition of human acetylcholinesterase and butyrylcholinesterase by methylene violet 3RAX, Computed Properties of 4569-86-2, the publication is Chemico-Biological Interactions (2019), 108845, database is CAplus and MEDLINE.

Phenazines, naturally produced by bacteria and archaeal Methanosarcina species are nitrogen-containing tricyclic mols. with antibiotic, antitumoral, and antiparasitic activities. Phenazines are used as electron acceptors-donors in wide range of fields including environmental biosensors. In this study, the inhibitory effects of a synthetic phenazine dye, methylene violet 3RAX (also known as di-Et safranine) on human erythrocyte AChE and human plasma BChE were tested and also its inhibitory mechanisms for both enzymes were studied in detail. Kinetic anal. showed that methylene violet 3RAX acts as a hyperbolic noncompetitive inhibitor of AChE with K_i value of 1.58 ± 0.36μM; α = 1; β = 0.12 ± 0.0003. On the other hand, it caused linear competitive inhibition of BChE with K_i value of 0.51 ± 0.006μM; α = ∞. In conclusion, methylene violet 3RAX which is a highly effective inhibitor of both human AChE and human BChE with K_i values in low micromolar range may be a promising candidate for the treatment of Alzheimer’s disease.

An enantioselective hydroxyalkylation of indoles and 7-azaindole with trifluoromethyl ketones was found to be effectively promoted under high-pressure conditions with a low loading of Cinchona alkaloids (e.g., 1-3 mol% of cinchonidine). Chiral tertiary alcs. containing a trifluoromethyl group were obtained at 9 kbar with good yield and enantioselectivity up to 89%, whereas usually merely traces of products were detected at atm. pressure.

Inhibition of diacylglycerol acetyl transferase 1 is of great interest in the treatment of diabetes, obesity and other diseases that constitute the metabolic syndrome. Small mol. inhibitors of the enzyme are often dogged with physicochem. property-related problems such as poor solubility Herein, the optimization of a series of biphenyl acetic acid inhibitors is reported. Focus on ligand efficiency and ligand lipophilicity efficiency and a strategy based on conformational restriction led to compounds with excellent potency and ADMET properties, culminating in the discovery of AZD2353.
