Abstract
Osteoarthritis (OA) is a common debilitating disease affecting articular joints for which no effective disease-modifying early diagnosis or medical therapy tools are currently available. The inefficient delivery of drugs into inflamed chondrocytes has restricted the development of anti-OA medication. Evidence has shown that inflammatory neutrophils possess the property of targeting inflammation via inflammatory tissue recruiting. Herein, we report neutrophil-cell-membrane-based biomimetic nanoparticles (NM-LANPs@Ru) as an OA theranostic nanoplatform; they act as a NO delivery system, coating neutrophil cell membrane onto the surface of self-assembled PEGylated L-arginine nanoparticles (LANPs) to act as a NO donor and loading a Ru complex to act as a ROS inducer. NM-LANPs@Ru demonstrated the specific targeting of inflamed OA with low toxicity, good NO release, and excellent fluorescence/photoacoustic (FL/PA) imaging properties. We showed that NM-LANPs@Ru exhibited enhanced cellular association in inflamed chondrocyte cells (C28/I2), much higher than NO release from ROS oxidized LA, and it improved the inhibition of the apoptosis of inflamed C28/I2 cells compared with control treatments. In vivo studies demonstrated that NM-LANPs@Ru effectively targeted inflamed OA, based on real-time dual-modal FL/PA imaging, eventually exhibiting its excellent anti-inflammatory activity. Our study may provide a new approach for the early diagnosis and treatment of osteoarthritis using a neutrophil-cell-membrane-based biomimetic nanoplatform for NO or drug delivery.

Ruthenium(II) Polypyridyl Complexes and Their Use as Probes and Photoreactive Agents for G-quadruplexes Labelling. Molecules 2022; 27:molecules27051541. [PMID: 35268640 PMCID: PMC8912042 DOI: 10.3390/molecules27051541] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 02/21/2022] [Accepted: 02/22/2022] [Indexed: 02/01/2023] Open
Abstract
Due to their optical and electrochemical properties, ruthenium(II) polypyridyl complexes have been used in a wide array of applications. Since the discovery of the light-switch ON effect of [Ru(bpy)2dppz]2+ when interacting with DNA, the design of new Ru(II) complexes as light-up probes for specific regions of DNA has been intensively explored. Amongst them, G-quadruplexes (G4s) are of particular interest. These structures formed by guanine-rich parts of DNA and RNA may be associated with a wide range of biological events. However, locating them and understanding their implications in biological pathways has proven challenging. Elegant approaches to tackle this challenge relies on the use of photoprobes capable of marking, reversibly or irreversibly, these G4s. Indeed, Ru(II) complexes containing ancillary π-deficient TAP ligands can create a covalently linked adduct with G4s after a photoinduced electron transfer from a guanine residue to the excited complex. Through careful design of the ligands, high selectivity of interaction with G4 structures can be achieved. This allows the creation of specific Ru(II) light-up probes and photoreactive agents for G4 labelling, which is at the core of this review composed of an introduction dedicated to a brief description of G-quadruplex structures and two main sections. The first one will provide a general picture of ligands and metal complexes interacting with G4s. The second one will focus on an exhaustive and comprehensive overview of the interactions and (photo)reactions of Ru(II) complexes with G4s.

Abstract
A cobalt(III) complex, [Co(L)2 ](ClO4 )3 (1), in which the ligand L was N,N-diethyl-4-(2,2':6',2''-terpyridin-4'-yl)aniline (L), was synthesized and fully characterized. This new cobalt(III) complex 1 exhibited selective cytotoxicity against HeLa, T-24, A549, MGC80-3, HepG2, and SK-OV-3 cells with IC50 values in the micromolar range (0.52 - 4.33 μm), and it exhibited low cytotoxicity against normal HL-7702 cells. The complex 1 was the most potent against the T-24 cells. It was found that 1 could cause the cell cycle arrest in G1 phase, and it exerted its antitumor activity mainly via disruption of mitochondrial function.
