Anticancer activity of G4-targeting phenoxazine derivatives in vitro. Biochimie 2022; 201:43-54. [PMID: 35817132 DOI: 10.1016/j.biochi.2022.07.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 06/27/2022] [Accepted: 07/01/2022] [Indexed: 11/02/2022]
Abstract
G4-stabilizing ligands are now being considered as anticancer, antiviral and antibacterial agents. Phenoxazine is a promising scaffold for the development of G4 ligands. Here, we profiled two known phenoxazine-based nucleoside analogs and five new nucleoside and non-nucleoside derivatives against G4 targets from telomere repeats and the KIT promoter region. Leading new derivatives exhibited remarkably high G4-stabilizing effects (comparable or superior to the effects of the commonly used selective G4 ligands PDS and NMM) and selectivity toward G4s over duplex (superior to BRACO-19). All phenoxazine-based ligands inhibited cellular metabolic activity. The phenoxazine derivatives were particularly toxic for lung adenocarcinoma cells A549' and human liver cancer cells HepG2 (CC50 of the nucleoside analogues in the nanomolar range), but also affected breast cancer cells MCF7, as well as immortalized fibroblasts VA13 and embryonic kidney cells HEK293t (CC50 in the micromolar range). Importantly, the CC50 values varied mostly in accordance with G4-binding affinities and G4-stabilizing effects, and the phenoxazine derivatives localized in the cell nuclei, which corroborates G4-mediated mechanisms of action.

The role of the cell surface glycocalyx in drug delivery to and through the endothelium. Adv Drug Deliv Rev 2022; 184:114195. [PMID: 35292326 DOI: 10.1016/j.addr.2022.114195] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 02/05/2022] [Accepted: 03/08/2022] [Indexed: 11/20/2022]
Abstract
Cell membranes are key interfaces where materials engineering meets biology. Traditionally regarded as just the location of receptors regulating the uptake of molecules, we now know that all mammalian cell membranes are 'sugar coated'. These sugars, or glycans, form a matrix bound at the cell membrane via proteins and lipids, referred to as the glycocalyx, which modulate access to cell membrane receptors crucial for interactions with drug delivery systems (DDS). Focusing on the key blood-tissue barrier faced by most DDS to enable transport from the place of administration to target sites via the circulation, we critically assess the design of carriers for interactions at the endothelial cell surface. We also discuss the current challenges for this area and provide opportunities for future research efforts to more fully engineer DDS for controlled, efficient, and targeted interactions with the endothelium for therapeutic application.

Abstract
Characterizing how multidrug-resistant bacteria circumvent the action of clinically used or novel antibiotics requires a detailed understanding of how the antibiotics interact with and cross bacterial membranes to accumulate in the cells and exert their action. When monitoring the interactions of drugs with bacteria, it remains challenging to differentiate functionally relevant internalized drug levels from nonspecific binding. Fluorescence is a method of choice for observing dynamics of biomolecules. In order to facilitate studies involving aminoglycoside antibiotics, we have generated fluorescently labeled aminoglycoside derivatives with uptake and bactericidal activities similar, albeit with a moderate loss, to those of the parent drug. The method combines fluorescence microscopy with fluorescence-activated cell sorting (FACS) using neomycin coupled to nonpermeable cyanine dyes. Fluorescence imaging allowed membrane-bound antibiotic to be distinguished from molecules in the cytoplasm. Patterns of uptake were assigned to different populations in the FACS analysis. Our study illustrates how fluorescent derivatives of an aminoglycoside enable a robust characterization of the three components of uptake: membrane binding, EDPI, and EDPII. Because EDPI levels are weak compared to the two other types of accumulation and critical for the action of these drugs, the three components of uptake must be taken into account separately when drawing conclusions about aminoglycoside function.
