Kenji Sudo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9463236
    Abstract: A composition comprising the following composition: an AD vehicle including a synthetic peptide and a lipid, wherein the synthetic peptide includes the amino acid sequence KnLm (wherein n is 4 to 8 and m is 11 to 20), a carboxylvinyl polymer and an RSV antigen. The composition has an antibody producing ability which is further higher than that of a conventional mucosal vaccine, hence capable of exerting excellent anti-virus antigen-specific IgA antibody- and IgG antibody-inducing effect in the nasal wash and the serum, respectively, even with an extremely small quantity of an RSV antigen.

  • Patent number: 8125963
    Abstract: A radio communication method and apparatus generate a plurality of information signals and transmit the signals to a communication partner from a plurality of antennas. A plurality of combination of signals to be transmitted are selected. A transmission evaluation value is determined based on the signal noise ratio of each signal. After all combinations are evaluated, a transmission format suitable for sending a combination of signals is determined based on a highest evaluation value.

  • Publication number: 20090048310
    Abstract: [Problems] To provide an agent useful for the prevention or treatment of various diseases associated with the infection with acyclovir-resistant viruses of the family Herpesviridae, specifically various infectious caused by herpes viruses, such as varicella associated with varicella-zoster virus infection, herpes zoster associated with recurrent infection with latent varicella-zoster virus, and herpes labialis, herpes encephalitis and genital herpes associated with HSV-1 and HSV-2 infection, and the like. [Means for Solving Problems] An N-[2-[(4-substituted phenyl)amino]-2-oxoethyl]tetrahydro-2H-thiopyran-4-carboxamide derivative in which the phenyl group is substituted at position 4 by a specific 5- or 6-membered heteroaryl group. This derivative has an excellent anti-viral activity against acyclovir-resistant herpes viruses and, therefore, is effective for the treatment of the diseases as mentioned above.

  • Publication number: 20090042915
    Abstract: [Problems] To provide a medicament, particularly a pharmaceutical composition useful for preventing or treating a variety of diseases caused by infection of a virus of the Herpesviridae family. [Means for Solving Problems] The present invention relates to an anti-herpesvirus agent characterized by combining a helicase-primase inhibitor with a polymerase inhibitor. By combining the polymerase inhibitor with the helicase-primase inhibitor having different functional mechanisms, the anti-herpesvirus agent of the present invention achieves an extremely superior anti-herpesvirus activity compared with conventional administration of a polymerase inhibitor alone. Therefore, it is particularly effective in a case in which a sufficient therapeutic effect cannot be achieved only with a polymerase inhibitor. Further, since the doses of both agents can be kept low, it is also possible to perform treatment by lowering the effect of an adverse reaction to be concerned.

  • Publication number: 20090030049
    Abstract: [PROBLEMS] To provide a medicament useful for the treatment of genital herpes after the development of lesions. [MEANS FOR SOLVING PROBLEMS] An N-[2-[(4-substituted phenyl)amino]-2-oxoethyl]tetrahydro-2H-thiopyran-4-carboxamide derivative in which the phenyl group is substituted at position 4 by a specific 5- or 6-membered heteroaryl group has an excellent anti-herpesvirus effect and can exert excellent therapeutic effect on genital herpes after the development of lesions. Therefore, the compound is useful for the treatment of genital herpes after the development of lesions.
