  • Publication number: 20230165988
    Abstract: A photosensitizer formulation can be disposed on or in a container. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation.

    Inventors: James Chongchu Chen, Celesta Jane Bjornson, John David Bjornson, LuAnn Lawton Chen, Stephanie Marie Chong-Ming Chen, Daniel Duong Hoang, Kathleen Clare Lendvay, Paul Deven Rolley
  • Publication number: 20230035662
    Abstract: A photosensitizer formulation can be disposed on or in a mesh; net; netting; screen; curtain of strands, fibers, or monofilaments; substrate, personal protective gear, mask, or any other suitable object. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation. A fluorescent formulation may be included to monitor photobleaching. The photosensitizer formulation may be disposed in a concentration gradient to generate antigenic particles by damaging or destroying microbes.

  • Patent number: 6313338
    Abstract: A process for preparing N-[1-(S)-ethoxycarbonyl-3-phenylpropyl]-L-alanine N-carboxyanhydride of the following formula (I), is to react N-[1-(S)-ethyoxy carbonyl-3-phenylpropyl]-L-alanine with XCOOR, wherein X is halogen atom, R is C1-C6 alkyl, to obtain a N-alkoxycarbonyl compound, then reacting with an acyl group activation reagent, finally contact with water. The compound of formula (I) is a key intermediate of ACE inhibitors.
