Eleven compounds were obtained from L., including two novel ketone alkaloids, (, ), 4-hydroxy-3-methoxybenzamide () (isolated for the first time), β-adenosine (), oleracrylimide A and B (, ), oleracein H, C, D, Q and A (-). The two novel ketone alkaloids were identified as 5-acetyl-5-methylcyclopent-2-ene-1-carboxamide (), named oleraciamide H, and (2 R,3S,4R,5R)-5-((R)-1,2-dihydroxyethyl)-3,4-dihydroxytetrahydrofuran-2-yl glycinate (), named oleracone Q by spectroscopic methods, including 1D, 2D NMR and compound fingerprints. Additionally, their anti-inflammatory activities were tested RAW 264.7 cells induced by LPS and found that they could significantly inhibit the release of IL-1 and TNF-.

Lipid metabolic remodeling delays senescence of T cells to potentiate their immunity against solid tumors.

Background: Tumor cells can drive the senescence of effector T cells by unbalancing their lipid metabolism, thereby limiting adoptive T cell therapy and contributing to tumor immune evasion. Our objective is to provide a feasible strategy for enhancing T cell treatment efficacy against solid tumors.
Methods: In this study, liposomal arachidonyl trifluoromethyl ketone (ATK) was anchored onto the adoptive T cell surface via bioorthogonal reactions, aiming to specifically inhibit the group IVA cytosolic phospholipase Aα (cPLAα), a key enzyme facilitating phospholipid metabolism and senescent state of T cells.
Dearomative Addition-Hydrogen Autotransfer for Branch-Selective -Heteroaryl C-H Functionalization via Ruthenium-Catalyzed C-C Couplings of Diene Pronucleophiles.

A novel mechanism for -heteroaryl C-H functionalization via dearomative addition-hydrogen autotransfer is described. Upon exposure to the catalyst derived from RuHCl(CO)(PPh) and Xantphos, dienes - suffer hydroruthenation to form allylruthenium nucleophiles that engage in -heteroaryl addition-β-hydride elimination to furnish branched products of C-C coupling - and -. Oxidative cleavage of isoprene adducts , , , and followed by ruthenium-catalyzed dynamic kinetic asymmetric ketone reduction provides enantiomerically enriched -heteroarylethyl alcohols - and, therefrom, -heteroarylethyl amines -.

We introduce mechanochemical deracemization (MCDR) as a novel strategy for obtaining enantiopure compounds. This study demonstrates the successful transposition of six archetypical deracemization reactions from a solvent-based to a solvent-minimized ball milling environment. The scope includes a ketone, isoindolinones, imines, an ester, and an inorganic compound, all of which deracemized successfully.

Background: Chalcones have been described in the literature as promising antineoplastic compounds.
Objectives: Therefore, the objective of this study was to analyze the cytotoxic effect of 23 synthetic chalcones on human acute leukemia (AL) cell lines (Jurkat and K562).
Methods: Cytotoxicity assessment was performed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method.
Microtubule acetylation and PERK activation facilitate eribulin-induced mitochondrial calcium accumulation and cell death.

Over the past few decades, microtubules have been targeted by various anticancer drugs, including paclitaxel and eribulin. Despite their promising effects, the development of drug resistance remains a challenge. We aimed to define a novel cell death mechanism that targets microtubules using eribulin and to assess its potential in overcoming eribulin resistance.
