Abstract
Pancreatic cancer, is an aggressive type of cancer and the most common malignancy with a poor prognosis regarding metastatic disease (survival < 10 %). The development of Novel chemotherapeutic drugs holds significant prospects for practical applications. Here, this work focuses on the interaction between two lanthanide complexes, Yb-BZA and Er-BZA, with DNA, as well as their anticancer activity against pancreatic cancer. The relationship between complexes and DNA is revealed by fluorescence, absorption spectral titration, cyclic voltammetric (CV) experiments, indicating that the Yb-BZA and Er-BZA interact with FS-DNA by bind groove. Moreover, molecular docking technology was utilized to confirm the binding of Yb-BZA and Er-BZA with 1BNA and 4AV1. The cytotoxic effects of Yb-BZA and Er-BZA on cancer cells BxPC-3 were evaluated, Yb-BZA (IC50 = 6.459 μg/mL) is more effective than oxaliplatin (IC50 = 16.46 μg/mL) evaluated using cytotoxicity assay. Yb-BZA and Er-BZA has the potential to become a chemotherapy drug for pancreatic cancer cells.

Int J Biol Macromol 2023; 253:126716. [PMID: 37673158 DOI: 10.1016/j.ijbiomac.2023.126716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 08/29/2023] [Accepted: 09/03/2023] [Indexed: 09/08/2023]
Abstract
This research seeks to optimize a chitosan-stabilized Pickering emulsion (PE) containing 5-fluorouracil (5-FU) as a potential Squamous Cell Carcinoma therapy. The 5-Fluorouracil was also thoroughly analysed using UV spectrophotometry and RP-HPLC, demonstrating exceptional linearity, sensitivity, precision, and robustness. The techniques of characterization revealed Pickering emulsion (PE) morphology, solid-like gel properties, successful encapsulation, and promising anticancer effects. FTIR was used to validate the efficacy of encapsulation, and DSC was used to confirm the post-encapsulation drug stability. The 0.6 % chitosan-stabilized PE showed exceptional stability and drug loading efficiency. Anti-EGFR-5-FU-CS-PE gel was developed for sustained drug release in the treatment of Squamous Cell Carcinoma. Anti-EGFR-5-FU-CS-PE demonstrated potent anticancer effects in vitro, with a lower IC50 than 5-FU and 5-FU-CS-PE. Anti-EGFR-5-FU-PE Pickering emulsions based on chitosan were investigated for their rheological properties, cellular interactions, and therapeutic potential. Both emulsions and gel exhibited sustained in vitro drug release after successful encapsulation. Anti-EGFR-5-FU-CS-PE induced apoptosis, decreased mitochondrial membrane potential, and inhibited the migration of cancer cells. Wistar mice were tested for safety and tumour growth inhibition. All formulations exhibited exceptional six-month stability. Anti-EGFR-5-FU-CS-PE emerges as a viable therapeutic option, necessitating additional research.

Abstract
Heterometallic {Eu2Cd2} complexes [Eu2(NO3)2Cd2(Phen)2(2,4-Nbz)8]n·2nMeCN (I) and [Eu2(MeCN)2Cd2(Phen)2(3,5-Nbz)10] (II) with the 2,4-dinitrobenzoate (2,4-Nbz) and 3,5-dinitrobenzoate (3,5-Nbz) anions and 1,10-phenanthroline were synthesized. The compounds obtained were characterized by X-ray single-crystal analysis, powder X-ray diffraction analysis, IR spectroscopy, and elemental analysis. Moreover, the thermal stability of the complexes was also studied. Analysis of the crystal packing showed that where 1,10-phenanthroline is combined with various isomers of dinitrobenzoate anions, different arrangements of non-covalent interactions are observed in the complex structures. In the case of the compound with the 2,4-dinitrobenzoate anion, these interactions lead to a significant distortion of the metal core geometry and formation of a polymeric structure, while the complex with the 3,5-dinitrobenzoate anion has a structure that is typical of similar systems. The absence of europium metal-centered luminescence at 270 nm wavelength was shown. For all the reported compounds, a thermal stability study was carried out that showed that the compounds decomposed with a significant thermal effect.
