The invention provides EXENDIN-4 analogue dimer and a preparation method and application thereof. The dimer is prepared from two same or different EXENDIN-4 analogues by forming a disulfide bond between the monomers through cysteine. The preparation method of the EXENDIN-4 analogue dimer comprises the steps of synthesizing an EXENDIN-4 analogue monomer by an Fmoc solid-phase polypeptide synthesis method, and forming the dimer from the monomer. The invention also provides an application of the EXENDIN-4 analogue dimer in preparing a medicine for treating diabetes mellitus and treating and / or preventing obesity or obesity-related diseases. The in-vivo half-life period of the EXENDIN-4 analogue dimer formed from the monomer provided by the invention can exceed 14-96 hours, which is obviously prolonged as compared with the half-life period (only 2.4 hours) of EXENDIN-4 in separate administration, thereby greatly facilitating the clinical popularization and application.

Free radicals and reactive oxygen species have the potential to damage a wide variety of organic molecules, typically by oxidizing certain moieties. These damaging species can, for example, be produced by an organism as a by-product of cellular respiration or by the reaction of iron(II) and peroxide. The present invention includes methods of using aryl-substituted heterocyclic iron chelating compounds as antioxidants, as well as preventing the reduction of iron(III) to iron(II). In addition, the present invention provides methods of treating conditions such as inflammatory disease, neoplastic disease, and ischemic episodes.

The invention provides a method of detecting surrogate markers for active tuberculosis in a serum sample. The surrogate markers are selected from serum mycolic acid antigen, serum anti-mycolic acid antibodies or both. The method includes the steps of combining the serum sample with a labelled monoclonal immunoglobulin antibody or fragment thereof to mycolic acids to produce a combined serum sample, the antibody or fragment thereof not substantially cross-reacting with cholesterol and the label being selected so that binding of the labelled antibody to immobilized mycolic acid antigen of mycobacterial origin produces a detectable signal and combining a blank sample with the labelled monoclonal immunoglobulin antibody or fragment thereof to mycolic acid to produce a combined blank sample. The method includes exposing both samples to immobilised mycolic acid antigen of mycobacterial origin or a synthetic analogue or analogues thereof so that the labelled immunoglobulin antibodies or fragments thereof in each sample bind to the immobilised antigen to produce detectable signals. If the surrogate markers are present, the signal produced by the blank sample will be stronger than that produced by the serum sample because of inhibition of binding of the labelled antibody in the serum sample arising from prior binding of the labelled antibody with the mycolic acid antigen in the serum sample or by competitive binding of serum anti-mycolic acid antibodies in the serum sample to the immobilised mycolic acid antigen or both.
