Latest Patents

Sikkema is named on 1 patent: “Therapeutic Carbon Nanomaterial HS Oxidants for Biological Polysulfide Synthesis.” The invention describes a method for catalytically forming persulfide and/or polysulfide from hydrogen sulfide in vitro and in vivo. It involves contacting cells with oxidized carbon nanoparticulate material containing carbonyl, hydroxyl, and carboxyl substituents.

The disclosed method is intended for cells affected by oxidative stress, traumatic brain injury, or hypoxia, as well as cells with excess hydrogen sulfide or deficient protein persulfidation. The patent describes preparing the material from various sources, with activated charcoal identified as a preferred source. It also describes water-dispersible material that remains dispersed for at least seven days at concentrations of about 1–5 mg/mL without added hydrophilic polymers. The material has a UV absorbance maximum in water of about 220 nm and can pass through a 0.22 μm pore PES membrane.
