Macrophage targeting precision nanomedicine utilizing ROS-responsive metallozyme-loaded nanomicelle for enhanced treatment of gout-induced inflammation.

The excessive accumulation of monosodium urate crystals in joints leads to the pathological condition known as gout. While conventional treatments, which include Non-steroidal Anti-inflammatory Drugs, are available, their short half-life and low bioavailability limit their practical application. To overcome these limitations and leverage the Reactive Oxygen Species (ROS)-rich microenvironment, this study developed a novel ROS-responsive thioketal-linked hyaluronic acid-based micelle loaded with manganese oxide (HTO-MnO) for enhanced treatment.

A bleomycin-mimicking manganese-porphyrin-conjugated mitochondria-targeting peptoid for cancer therapy.

Bleomycin (BLM) is a natural product with established anticancer activity, attributed to its ability to cleave intracellular DNA. BLM complexes with iron (BLM-Fe) exhibit peroxidase-like activity, generate reactive oxygen species (ROS), and cause DNA cleavage. Inspired by the mechanism of BLM, we synthesized a novel conjugate of manganese tetraphenylporphyrin (MnTPP) with a biomimetic peptoid (i.

Reactive oxygen species driven prodrug-based nanoscale carriers for transformative therapies.

Reactive oxygen species (ROS) drive processes in various pathological conditions serving as an attractive target for therapeutic strategies. This review highlights the development and use of ROS-dependent prodrug-based nanoscale carriers that has transformed many biomedical applications. Incorporating prodrugs into nanoscale carriers not only improves their stability and solubility but also enables site-specific drug delivery ultimately enhancing the therapeutic effectiveness of the nanoscale carriers.

Hyaluronic acid: A review on its biology, aspects of drug delivery, route of administrations and a special emphasis on its approved marketed products and recent clinical studies.

Hyaluronic acid (HA) is a large non-sulphated glycosaminoglycan that is an important component of extracellular matrix (ECM) and a biodegradable polymer. Due to a variation in its molecular weight, HA derivatives can be utilized to make different formulations like fillers, creams, gels and drops. HA based drug research has seen a recent surge largely due to some properties like mucoadhesion, biocompatibility and ease of chemical modification.
