Comprehensive analysis of a widely pharmaceutical, furosemide, and its degradation products in aquatic systems: Occurrence, fate, and ecotoxicity.

Many pharmaceutical compounds end up in the environment due to incomplete removal by wastewater treatment plants (WWTPs). Some compounds are sometimes present in significant concentrations and therefore represent a risk to the aquatic environment. Furosemide is one of the most widely used drugs in the world.

Occurrence and fate of an emerging drug pollutant and its by-products during conventional and advanced wastewater treatment: Case study of furosemide.

Conventional wastewater treatment systems are not designed to remove pharmaceutical compounds from wastewater. These compounds can be degraded into many other transformation products which are hardly, if at all, studied. In this context, we studied the occurrence and degradation of furosemide, a very frequently detected diuretic, along with its known degradation products in several types of wastewater.

A new human pyridinium metabolite of furosemide, inhibitor of mitochondrial complex I, is a candidate inducer of neurodegeneration.

Pharmaceuticals and their by-products are increasingly a matter of concern, because of their unknown impacts on human health and ecosystems. The lack of information on these transformation products, which toxicity may exceed that of their parent molecules, makes their detection and toxicological evaluation impossible. Recently we characterized the Pyridinium of furosemide (PoF), a new transformation product of furosemide, the most widely used diuretic and an emerging pollutant.

Highly potent anti-CD20-RLI immunocytokine targeting established human B lymphoma in SCID mouse.

Rituximab (RTX), a chimeric IgG1 monoclonal antibody directed against the CD20 antigen, has revolutionized the treatment of B-cell malignancies. Nevertheless, the relapsed/refractory rates are still high. One strategy to increase the clinical effectiveness of RTX is based on antibody-cytokine fusion protein (immunocytokine; ICK) vectorizing together at the tumor site the antibody effector activities and the cytokine co-signal required for the generation of cytotoxic cellular immunity.
