Abstract
Nicotinamide adenine dinucleotide (NAD+) plays a crucial role in the cellular energy metabolism pathway. Nicotinamide phosphoribosyltransferase (NAMPT) is a rate-limiting enzyme involved in the biosynthesis of NAD+. Herein, a series of new NAMPT activators were designed to increase the NAD+ levels and improve aging-associated dysfunctions. In particular, compound C8 effectively activated NAMPT and promoted the biosynthesis of NAD+. Furthermore, we demonstrated that NAMPT activator C8 possessed excellent antiaging effects both in vitro and in vivo. Activator C8 showed potent activity in delaying aging in senescent HL-7702 cells and extended the lifespan of Caenorhabditis elegans. In a naturally aging mouse model, compound C8 effectively alleviated age-related dysfunctions and markers. Therefore, NAMPT activator C8 represented a promising lead compound for the treatment of age-related diseases.

Chen S, Ma X, Wang H, Wang L, Wu Y, Wang Y, Li Y, Fan W, Niu C, Hou S. Visualize intracellular β-galactosidase using an asymmetric near-infrared fluorescent probe with a large Stokes shift. Anal Chim Acta 2023; 1272:341482. [PMID: 37355329 DOI: 10.1016/j.aca.2023.341482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 05/16/2023] [Accepted: 06/04/2023] [Indexed: 06/26/2023]
Abstract
β-galactosidase (β-Gal) is an important biomarker of cell senescence and primary ovarian cancer. Therefore, it is of great significance to construct a near-infrared fluorescent probe with deep tissue penetration and a high signal-to-noise ratio for visualization of β-galactosidase in biological systems. However, most near-infrared probes tend to have small Stokes shifts and low signal-to-noise ratios due to crosstalk between excitation and emission spectra. Using d-galactose residues as specific recognition units and near-infrared dye TJ730 as fluorophores, a near-infrared fluorescence probe SN-CR with asymmetric structure was developed for the detection of β-Gal. The probe has a fast reaction equilibrium time (<12 min) with β-Gal, excellent biocompatibility, near-infrared emission (738 nm), low detection limit (0.0029 U/mL), and no crosstalk between the excitation spectrum and emission spectrum (Stokes shifts 142 nm) of the probe. Cell imaging studies have shown that SN-CR can visually trace β-Gal in different cells and distinguish ovarian cancer cells from other cells.

Abstract
The detection and quantification of apoptotic cells is a key process in cancer research, particularly during the screening of anticancer therapeutics and in mechanistic studies using preclinical models. Intravital optical imaging enables high-resolution visualisation of cellular events in live organisms; however, there are few fluorescent probes that can reliably provide functional readouts in situ without interference from tissue autofluorescence. We report the design and optimisation of the fluorogenic probe Apotracker Red for real-time detection of cancer cell death. The strong fluorogenic behaviour, high selectivity, and excellent stability of Apotracker Red make it a reliable optical reporter for the characterisation of the effects of anticancer drugs in cells in vitro and for direct imaging of chemotherapy-induced apoptosis in vivo in mouse models of breast cancer.
