Through research, I have a further understanding and discovery of Methyl 3-phenylpropionate

Fluorine-containing organic molecules, particularly those that bear (sp(3))C-F bonds, are rapidly gaining prominence in modern chemical synthesis. Although extensive studies have been devoted to the preparation of secondary and tertiary fluorides, crucial shortcomings remain: for example, lengthy substrate synthesis, contrived installation of difficult-to-remove directing/activating units, excessive waste generation and/or limited functional group compatibility. Here, we show that readily accessible alpha-onofluoro carboxylic acids, which are conventionally difficult substrates for cross-coupling, undergo direct decarboxylative crosscoupling with sp(2-) and sp(3-)hybridized organohalides to afford a wide assortment of fluorinated products. Reactions are typically promoted by a combination of 1 mol % of an Ir-based photocatalyst and 2-15 mol % of a bipyridine-Ni complex, delivering products in up to 86% yield under blue LED light irradiation. Concise synthesis of key therapeutic candidates underscores utility, complementarity, and distinct advantages compared with existing methods. DFT calculations are used to rationalize the distinct reactivity of alpha-fluoro carboxylic acid substrates (vs nonfluorinated parent acids) under decarboxylation conditions.

The reactivity of ortho-functionalized N-heterocycle-substituted iodoarenes (NHIAs) as organocatalysts in iodine(I/III)-mediated oxidations was systematically investigated in the alpha-tosyloxylation of ketones as the model reaction. During a systematic catalyst evolution, it was found that NH-triazoles and benzoxazoles have the most significant positive influence on the reactivity of the central iodine atom. A further catalyst improvement which focused on the substitution pattern of the arene revealed a remarkable ortho-effect. By introduction of an o-OMe group we were able to generate a novel NHIA with a so far unseen catalytic efficiency. This new catalyst is not only easy to synthesize but also enabled the alpha-tosyloxylation of carbonyl compounds at the lowest reported catalyst loading of only 1 mol%. Finally, the performance of this iodine(I) catalyst was successfully demonstrated in intramolecular oxidative couplings of biphenyls and oxidative rearrangements.

Using thianthrene S-oxide (TTSO) as a transient mediator, para-arylation and alkenylation of mono-substituted arenes have been demonstrated via a para-selective thianthrenation/Pd-catalyzed thio-Suzuki-Miyaura coupling sequence under mild conditions. This reaction features a broad substrate scope, and functional group and heterocycle tolerance. The versatility of this approach was further demonstrated by late-stage functionalization of complex bioactive scaffolds, and direct synthesis of some pharmaceuticals, including Tetriprofen, Ibuprofen, Bifonazole, and LJ570.

In this research, the antibacterial activity and the interaction mechanisms of the major chemical constituent present in the Alpinia galanga rhizomes essential oil (AGREO) were investigated. Ethyl cinnamate, methyl cinnamate and n-pentadecane were the major components of AGREO. The antibacterial mechanism of AGREO on Enterohemorrhagic Escherichia coli O157:H7 (EHEC O157) was evaluated and the results proved that the potent antibacterial activity of AGREO was due to higher passive permeability of bacterial cell membrane, followed by crucial intracellular components efflux. Additionally, AGREO disrupted the intracellular physiological metabolism of EHEC O157, including inhibition of P-type ATPases activity and down-regulation expression of four virulence genes associated with EHEC infections. Notably, molecular docking studies suggested that ethyl cinnamate probably competed with the structural NAD(P)(+) for the binding sites of glucose-6-phosphate dehydrogenase (G6PD), resulting in a decrease in G6PD activity with subsequent suppression of respiratory metabolism. The spectroscopic techniques and molecular docking studies proved that the AGREO major components were prone to bind to the minor groove of DNA.

The presence of different aldehydes is found to have a significant influence on the catalytic performance when using PN(H)P type ligands for dehydrogenation of alcohols. Accordingly, hybrid multi-dentate ligands were discovered based on an oxygen-transfer alkylation of PNP ligands by aldehydes. The relevant Ru-PNN(PO) system provided the desired unsymmetrical esters in good yields via acceptorless dehydrogenation of alcohols. Hydrogen bonding interactions between the phosphine oxide moieties and alcohol substrates likely assisted the observed high chemoselectivity.

In the present study, several decursin analogues (KC1-3) were synthesized and evaluated in terms of their antiseptic activities on high mobility group box 1 (HMGB1)-mediated septic responses and survival rate in a mouse model of sepsis. KC1 and KC3, but not KC2, significantly reduced HMGB1 release in lipopolysaccharide (LPS)-activated human umbilical vein endothelial cells (HUVECs) and attenuated the cecal ligation and puncture (CLP)-induced release of HMGB1. Additionally, in vitro analyses revealed that KC1 and KC3 both alleviated HMGB1-mediated vascular disruptions and inhibited hyperpermeability in mice, and in vivo analyses revealed that KC1 and KC3 reduced sepsis-related mortality and tissue injury. Taken together, the present results suggest that KC1 and KC3 both reduced HMGB1 release and septic mortality and, thus, may be useful for the treatment of sepsis.

The antigen-antibody interaction determines the sensitivity and specificity of competitive immunoassay for hapten detection. In this paper, the specificity of a monoclonal antibody against alternariol-like compounds was evaluated through indirect competitive ELISA. The results showed that the antibody had cross-reactivity with 33 compounds with the binding affinity (expressed by IC50) ranging from 9.4 ng/mL to 12.0 mu g/mL. All the 33 compounds contained a common moiety and similar substituents. To understand how this common moiety and substituents affected the recognition ability of the antibody, a three-dimensional quantitative structure-activity relationship (3D-QSAR) between the antibody and the 33 alternariol-like compounds was constructed using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) methods. The q(2) values of the CoMFA and CoMSIA models were 0.785 and 0.782, respectively, and the r(2) values were 0.911 and 0.988, respectively, indicating that the models had good predictive ability. The results of 3D-QSAR showed that the most important factor affecting antibody recognition was the hydrogen bond mainly formed by the hydroxyl group of alternariol, followed by the hydrophobic force mainly formed by the methyl group. This study provides a reference for the design of new hapten and the mechanisms for antibody recognition.

The aim of this work was to undertake a detailed analysis on chemical constituents of brown propolis, originating from four different states (Bahia, Minas Gerais, Parana and Sergipe) of Brazil. The volatile profile was determined by using HS-SPME-GC-MS along with the determination of total phenolic compounds content, flavonoids and antioxidant activity. A total of 315 volatile compounds were identified, however, several of them have not been reported so far in the Brazilian brown propolis. The terpenes represented the major class with 40.92-84.66% of the total area in the chromatograms. PCA analysis of the majority of compounds successfully indicated the volatile profile of each propolis sample according to their geographical origin. The analysis of volatile compounds and its characterization also varied significantly and confirmed that these depended on the geographical area of collection of propolis. The data generated in this work may help in establishing criteria for quality control and tracking the specific region of propolis production in different states of Brazil.

An unprecedented approach for assembling a broad range of 1,2-diarylethane derivatives with fluorine-containing fully substituted carbon centers was developed. The protocol features straightforward operation, proceeds under metal-free condition, and accommodates a large variety of synthetically useful functionalities. The critical aspect to the success of this novel transformation lies in using aryldiazonium salts as both aryl radical progenitor and also as single electron acceptor which elegantly enables a radical-polar crossover manifold.
