  • Patent number: 12029797
    Abstract: Provided is a labeled fatty acid derivative for diagnostic imaging that enables quantification of fatty acid metabolic activity in the heart muscle. [Means for Solution] The present inventors have conducted intensive investigations on a method that enables quantification of fatty acid metabolic activity and thus have found that a labeled fatty acid derivative typified by 3-{[(5Z)-3-[18F]fluorotetradeca-5-en-1-yl]sulfanyl}propanoic acid or a salt thereof has excellent accumulation to the heart muscle and thus enables imaging of fatty acid metabolic activity by positron emission tomography (PET). Therefore, the labeled fatty acid derivative of the present invention can be used as a radiolabeled tracer for rapid and non-invasive quantification of fatty acid metabolic activity in the heart muscle, diagnostic imaging of heart disease typified by an ischemic heart disease, diagnostic imaging of the therapeutic effect of a therapeutic drug for heart disease, and the like.

  • Publication number: 20240209108
    Abstract: An object of the present invention is to provide an anti-CLDN4/anti-CD137 bispecific antibody usable in treatment of cancer. An anti-CLDN4/anti-CD137 bispecific antibody produced using an anti-CLDN4 antibody binding to CLDN4 and an anti-CD137 antibody binding to CD137 had agonistic activity for CD137, promoted production of interferon ? by a T cell, and exhibited cytotoxic activity against a cancer cell expressing CLDN4 on a cell surface thereof. Besides, it was shown that the anti-CLDN4/anti-CD137 bispecific antibody can be safely administered to monkeys. Therefore, the anti-CLDN4/anti-CD137 bispecific antibody is usable in treatment of human cancer.
