A Selectfluor-mediated approach for the synthesis of β-acyl allyl sulfones/β-acyl allyl benzotriazoles with excellent atom economy from readily available acetophenones/aryl acetylenes, aryl sulfinates/benzotriazoles, and dimethyl sulfoxide (DMSO) is described. In this protocol, DMSO acts as a dual-carbon synthon, resulting in a transition-metal-free construction of two C-C and one C-S or two C-C and one C-N bonds in one pot. This approach is extended to generate chemically diverse compounds. Additionally, β-acyl allyl sulfones/β-acyl allyl benzotriazoles were prepared from acetylenes instead of acetophenones.

Putative Transformation Mechanism of γ-l-Glutamyl-S-Allyl-l-Cysteine during the Processing of Black Garlic.

γ-l-Glutamyl-S-allyl-l-cysteine (GSAC) is renowned for its flavor-modifying effects and beneficial biological activities. However, the level of GSAC decreases significantly during the processing of black garlic, and the pathways and degradation products resulting from this decline remain unclear. To investigate the potential transformation mechanisms of GSAC in black garlic, simulation systems for thermal decomposition, Maillard reactions, and enzymatic hydrolysis were established.

The synthesis of ()-1-(1,3-diphenylallyl)-1-1,2,4-triazoles and related compounds as anti-mitotic agents with activity in breast cancer was investigated. These compounds were designed as hybrids of the microtubule-targeting chalcones, indanones, and the aromatase inhibitor letrozole. : A panel of 29 compounds was synthesized and examined by a preliminary screening in estrogen receptor (ER) and progesterone receptor (PR)-positive MCF-7 breast cancer cells together with cell cycle analysis and tubulin polymerization inhibition.

A straightforward synthetic route towards DAB-1 scaffolded dimeric iminosugars is described here, starting from readily available bis-glycosylamines. The method allows the integration of a variety of linkages (aryl, alkyl, polyethyleneglycol chains) between both iminosugars through the choice of the bis-amine used in the first step. Moreover, an additional substituent (allyl, ethynyl) may be inserted into the structure via nucleophilic addition of an organometallic reagent to the starting bis-glycosylamine.

Glucosinolates are chemically stable compounds that exhibit biological activity in the body following hydrolysis catalyzed by the enzyme myrosinase. While existing and studies suggest that the hydrolysis products of glucosinolates predominantly exert beneficial effects in both human and animal organisms, some studies have found that the excessive consumption of glucosinolates may lead to toxic and anti-nutritional effects. Given that glucosinolates are primarily ingested in the human diet through dietary supplements and commercially available cruciferous vegetables, we investigated the effects of the glucosinolate sinigrin on molecular markers in the myocardia of healthy Swiss mice.

Multi-drug-resistant (MDR) pathogens represent a critical global health threat, necessitating the development of novel antimicrobial agents with broad-spectrum activity and minimal toxicity. This study investigates the antimicrobial and anti-biofilm properties of 4-Allyl-2-methoxyphenol (eugenol, EU) and (E)-3-Phenylprop-2-enal (cinnamaldehyde, CN) against 19 clinically significant pathogens through a combination of in-vitro assays and in-silico analyses. EU displayed remarkable activity, particularly against Aspergillus niger (20.
