ProLindac (AP5346) is DACH (diaminocyclohexane) platinum polymer prodrug currently in phase II clinical development. It uses a 25 kDa polymer delivery vehicle based on hydroxypropylmethacrylamide (HPMA) to target the active form of the approved drug oxaliplatin to tumors. The pH-sensitive linker that binds platinum to the polymer releases platinum more rapidly in low pH environments, as found typically in many tumors. This review summarizes the development of ProLindac to date, including preclinical efficacy studies, the phase I monotherapy clinical study in patients with solid tumors, and the phase I/II monotherapy study in patients with recurrent ovarian cancer. Both preclinical and clinical study data indicate that ProLindac exhibits efficacy at least equal to, and likely superior to oxaliplatin, while demonstrating excellent tolerability. Additional clinical studies of ProLindac used in combination with other chemotherapeutic agents are planned.

Hybrid nano-sized motors with navigation and self-actuation capabilities have emerged as promising nanocarriers for a wide range of delivery, sensing, and diagnostic applications due to their unique ability to achieve controllable locomotion within a complex biological environment such as tissue. However, most current nanomotors typically operate using a single driving mode, whereas propulsion induced by both external and local stimuli could be more beneficial to achieve efficient motility in a biomedical setting. In this work, we present a hybrid nanomotor by functionalizing biodegradable stomatocytes with platinum nanoparticles (Pt NPs).

Electrochemical oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) provides an environmentally friendly route for producing the sustainable polymer monomer 2,5-furandicarboxylic acid (FDCA). Thus, precisely adjusting the synergistic adsorption among key reactive species, such as HMF and OH, on the carefully designed catalyst surface is essential for achieving satisfactory catalytic performance for HMF oxidation to FDCA as it is closely related to the adsorption strength and configuration of the reaction substrates. This kind of regulation will ultimately facilitate the improvement of HMF oxidation performance.

Metallic nanostructures play a vital role in technological advancement, providing exceptional performance and improved adaptability in comparison to their bulk equivalents. Conventional synthesis techniques frequently depend on dangerous reducing agents to transform metal ions into Nanoparticles (NPs), which presents considerable environmental and health issues. In contrast, the approach of green synthesis, which emphasizes the use of non-toxic reagents, has garnered significant interest as a sustainable method for the fabrication of Metallic Nanoparticles (MNPs).

Recent research has demonstrated that activating the cGAS-STING pathway can enhance interferon production and the activation of T cells. A manganese complex, called TPA-Mn, was developed in this context. The reactive oxygen species (ROS)-sensitive nanoparticles (NPMn) loaded with TPA-Mn are developed.
