  • Publication number: 20250127898
    Abstract: The present invention relates to reduced chlorin analogues and their pharmaceutically acceptable salts, and compositions comprising reduced chlorin analogues and their pharmaceutically acceptable salts. Reduced chlorin analogues and pharmaceutically acceptable salts thereof are suitable for use in photodynamic therapy, cytoluminescent therapy and photodynamic diagnosis, for example, for treating or detecting a tumour, or for antiviral treatment. The present invention also relates to the use of reduced chlorin analogues and pharmaceutically acceptable salts thereof in the manufacture of a phototherapeutic or photodiagnostic agent, and to a method of photodynamic therapy, cytoluminescent therapy or photodynamic diagnosis, for example, for treating or detecting a tumour, or for antiviral treatment.

  • Patent number: 11725048
    Abstract: The present invention relates to C-X-C motif chemokine ligand 10 (CXCL10) binding proteins and uses thereof in methods of detecting and/or diagnosing a condition in a subject, comprising determining a level of CXCL10 in the subject. Specific antibodies that bind to total CXCL10 (full-length, N-terminally truncated and citrullinated) and antibodies that bind active CXCL10 (full-length) were used to measure the level of total and active CXCL10 in samples from ovarian cancer patients. The calculated ratio of active to total CXCL10 was lower in patients with malignant condition when compared to patients with benign tumours or healthy individuals and is the basis of method of diagnosis of malignant conditions, monitoring tumour burden and disease progression.
