AI Article Synopsis

  • Chronic inflammation from inflammatory bowel disease can lead to colitis-associated colorectal cancer (CACRC), which is linked to oxidative stress and inflammation.
  • A study tested a series of gold(III) complexes (TGS 121, 404, 512, 701, 702, and 703) on both cancerous and normal colon cell lines, as well as in a mouse model of CACRC.
  • TGS 121, 404, and 702 showed the most promise for reducing tumors and inflammation, suggesting their potential as new treatments for colorectal cancer.

Article Abstract

Background: Chronic inflammation in the course of inflammatory bowel disease may result in colon cancer, or colitis-associated colorectal cancer (CACRC). It is well established that CACRC is associated with oxidative stress and secretion of multiple pro-inflammatory cytokines, e.g. tumor necrosis factor-α. Recently, we proved that the administration of gold(III) complexes resulted in the alleviation of acute colitis in mice. The aim of the current study was to assess the antitumor effect of a novel series of gold(III) complexes: TGS 121, 404, 512, 701, 702, and 703.

Materials: Analyzed gold(III) complexes were screened in the in vitro studies using colorectal cancer and normal colon epithelium cell lines, SW480, HT-29, and CCD 841 CoN, and in vivo, in the CACRC mouse model.

Results: Of all tested complexes, TGS 121, 404, and 702 exhibited the strongest anti-tumor effect in in vitro viability assay of colon cancer cell lines and in in vivo CACRC model, in which these complexes decreased the total number of colonic tumors and macroscopic score. We also evidenced that the mechanism of action was linked to the enzymatic antioxidant system and inflammatory cytokines.

Conclusions: TGS 121, 404, and 702 present anti-tumor potential and are an attractive therapeutic option for colorectal cancer.

Rationalizing the impact of oxidation states of Au-based complexes on function require synthetic strategies that allow for conserved molecular formula in Au(I) and their Au(III) counterparts. Oftentimes achieving Au(I) and Au(III) coordination complexes with the same ligand system is challenging due to the reactivity and stability of the starting Au(I) or Au(III) starting materials. Thus, attempts to study the impact of oxidation state on biological function has been elusive.

The onset of resistance to artemisinin for malaria treatment has stimulated the quest for novel antimalarial drugs. Herein, the gold(III) coordination complexes Aubipy [Au(bipy)Cl] (bipy = 2,2'-bipyridine), Auphen [Au(phen)Cl] (phen = phenanthroline), Auterpy [Au(terpy)Cl] (terpy = 2,2';6',2″-terpyridine), and corresponding hydrolyzed species, have been investigated as inhibitors of the Plasmodium falciparum aquaglyceroporin (PfAQP) protein by computational methods. Through an in-silico approach using an Umbrella Sampling protocol to sample how Aubipy, Auphen, and Auterpy permeate through the PfAQP, their permeability coefficients were estimated using the Inhomogeneous Solubility Diffusion (ISD) model with promising results.

Lead (Pb) and hexavalent chromium (Cr) are highly toxic pollutants with no safe exposure levels, posing significant health risks globally, especially in developing countries. Current detection methods for these metals are often complex and inaccessible, highlighting the urgent need for innovative approaches. In this study, we present a rapid, cost-effective colorimetric assay utilizing ascorbic acid-capped gold nanoparticles (AuNPs) for the selective detection of Pb and Cr ions at levels recommended by regulatory bodies such as the WHO and EPA.

The elusiveness of triple-negative breast cancer from targeted therapy has redirected focus toward exploiting the metabolic shortcomings of these highly metastatic subtypes of breast cancer. Cueing from the metabolic heterogeneity of TNBC and the exposition of the dual dependence of some TNBCs on OXPHOS and glycolysis for ATP, we herein report the efficacy of cotreatment of TNBCs with an OXPHOS inhibitor, 2a and 2DG, a potent glycolysis inhibitor. 2a-2DG cotreatment inhibited TNBC cell proliferation with IC of ∼5 to 36 times lower than that of 2a alone and over 5000 times lower than IC of 2DG alone.

A unique class of tridentate diaryltriazine ligand-containing gold(III) complexes with thermally activated delayed fluorescence (TADF) and/or thermally stimulated delayed phosphorescence (TSDP) properties has been designed and synthesized. With a simple structural modification on the coordination of carbazole moiety in the monodentate ligand, a large spectral shift of ∼160 nm (ca. 4900 cm) spanning from sky blue to red emissions has been demonstrated in solid-state thin films.
