The synthesis of air-stable ligand-free nanopalladium hydride (PdNHx) in water was achieved and applied to various organic transformations, including (1) reduction of heteroaromatics such as (iso)quinolines, phenanthrolines, benzotriazole, and naphthyridines, (2) regio- and chemoselective reduction of nitroarenes, (3) alkyne reductions, (4) chemoselective dehalogenation, and (5) base-free detriflation. Both the synthesis of PdNHx and the reductions were carried out under mild conditions in a micellar medium using our designer surfactant PS-750-M, which eliminates the need for toxic organic solvents and extremely high hydrogen pressure and temperature. Notably, PS-750-M is also a replacement of hazardous polar-aprotic solvents. This newer approach for selective …

Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.
The purpose of this study is to …

Cisplatin is a chemotherapy compound effective against a variety of cancers. However, it can act as an ototoxin and cause hearing loss by promoting reactive oxygen species (ROS) production in auditory tissues. The antioxidant amino acid, L-serine has been hypothesized to lower levels of cisplatin-mediated ROS. In this project, we investigated whether L-serine can reduce cisplatin-mediated ROS production in auditory tissue and potentially act as an otoprotectant during cisplatin chemotherapy. We used a zebrafish utricular tissue culture system and fluorescent ROS indicator dye to spectrophotometrically measure if L-serine could decrease reactive oxygen species levels in cisplatin-treated tissues. We found that …
