Latest Patents

Kahn is named on 1 patent: “Therapeutic Carbon Nanomaterial HS Oxidants for Biological Polysulfide Synthesis.” The patent describes a method for catalytically forming persulfide or polysulfide from hydrogen sulfide in vitro and in vivo. It proposes 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 conditions involving excess hydrogen sulfide or deficient protein persulfidation. The patent identifies activated charcoal as a preferred source for preparing the oxidized carbon material. It also describes a water-dispersible formulation that remains dispersed for at least seven days at concentrations of about 1–5 mg/mL without added hydrophilic polymers. The material is reported to have a UV absorbance maximum near 220 nm in water and to pass through a 0.22 μm pore PES membrane.
