标题 :Solid phase and combinatorial synthesis of substituted 2-methylene-2, 3-dihydrothiazoles and of arrays of substituted 2-methylene-2, 3-dihydrothiazoles

摘要:A solid phase method for the synthesis of a plurality of differently substituted 2-methylenethiazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 2-methylenethiazoles are prepared by acylation of a substrate-bound primary or secondary amine with cyanoacetic acid and reaction of the resulting cyanoacetamide with an isothiocyanate in the presence of a base. Alkylation with an appropriate alkyl halide under acidic conditions yields differently substituted, support-bound 2-methylene-2,3-dihydrothiazoles. These may be screened on the substrate or cleaved from the substrate and then screened in solution. The efficient synthesis of a wide variety of 2-methylenethiazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiazole-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.

摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.

摘要:Some embodiments relate to genetically engineered bacterial strains for modulation of levels of the bacterial metabolite 4-ethylphenol (4EP) and its sulfated form, 4-ethylphenyl sulfate (4EPS). In some embodiments, the bacteria reduce or inhibit production of 4EP or 4EPS in the gut of a subject. The bacteria can ameliorate, delay the onset, or reduce the likelihood of one or more symptoms associated with anxiety and/or autism spectrum disorder (ASD) in the subject.
