We report the use of DOTA as a chelator for titanium. The resulting complex is fully characterised and stability studies reveal its high kinetic inertness against transmetallation and transchelation. The radiolabeling of DOTA with Ti, a guaiacol-based liquid-liquid extraction method, leads to a high radiochemical conversion up to 98%.

Introduction: The development of efficient and sustainable catalytic methodolo-gies has garnered considerable attention in contemporary organic synthesis.
Methods: Herein, we present a novel approach employing the Cu@DPP-SPION catalyst for the synthesis of ethyl 4-(aryl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate derivatives. This versatile catalytic system incorporates copper nanoparticles supported on 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)benzoic acid-functionalized superparamagnetic iron oxide nanoparticles (SPIONs).

The EGFR-driven angiogenesis is crucial in solid tumors, particularly through the delivery of biomolecules via extracellular vesicles (EVs), but the mechanism by which EGFR regulates EV cargo is still unclear. First, cell co-culture and murine tumor models were employed to examine the impact of EGFR overexpression on the pro-angiogenic properties of small EVs (sEVs) derived from oral squamous cell carcinoma (OSCC). Small RNA sequencing was then used to compare the miRNA profiles of OSCC-sEVs with and without EGFR overexpression, followed by functional enrichment and motif analyses of the differentially expressed miRNAs.

Purpose: Mastoparan-M (Mast-M) has cytotoxic effects on various tumor cells in vitro, including liver cancer and colorectal cancer. However, the anti-tumor mechanism of Mast-M remains unclear and its potential for anti-tumor therapy has not been investigated. Herein, we aimed to develop a novel phytosome formulation loaded with Mast-M and evaluate its efficacy against breast cancer both in vitro and in vivo.

Poor aqueous solubility and bioavailability limit the translation of new drug candidates into clinical applications. Nanocrystal formulations offer a promising approach for improving the dissolution rate and saturation solubility. These formulations are applicable for various routes of administration, with each presenting unique opportunities and challenges posed by the physiological barriers.

Background: Pancreatic adenocarcinoma (PAAD) is one of the most malignancy diseases. Lysine β-hydroxybutyrylation (Kbhb) has been reported to involve various metabolism and cancer progression.
Methods: Data from online databases (TCGA and GEO) were retrieved for the selection of differential expressed Kbhb site genes (DTRGs).
