    • Many pathogens, including Mycobacterium tuberculosis and Yersinia pestis, rely on an iron acquisition system based on siderophores, secreted iron-chelating compounds with extremely high Fe(III) affinity. The compounds of the invention are inhibitors of domain salicylation enzymes, which catalyze the salicylation of an aroyl carrier protein (ArCP) domain to form a salicyl-ArCP domain thioester intermediate via a two-step reaction. The compounds include the intermediate mimic 5′-O—[N-(salicyl)sulfamoyl]-adenosine (salicyl-AMS) and analogs thereof. These compounds are inhibitors of the salicylate activity of MbtA, YbtE, PchD, and other domain salicylation enzymes involved in the biosynthesis of siderophores. Therefore, these compounds may be used in the treatment of infection caused by microorganisms which rely on siderphore-based iron acquisition systems. Pharmaceutical composition and methods of using these compounds to treat or prevent infection are also provided as well as methods of preparing the inventive compounds.
    • 许多病原体,包括结核分枝杆菌和鼠疫耶尔森氏菌,依赖于铁铁捕获系统,其基于铁载体,具有极高Fe(III)亲和力的分泌铁螯合化合物。 本发明的化合物是结构域水解酶的抑制剂,其催化芳酰基载体蛋白(ArCP)结构域的水杨酸化以通过两步反应形成水杨酰-ArCP结构域的硫酯中间体。 所述化合物包括中间体模拟5'-O- [N-(水杨基)氨磺酰基] - 腺苷(水杨基-AMS)及其类似物。 这些化合物是参与铁载体生物合成的MbtA,YbtE,PchD和其他结构域水杨酸酶的水杨酸盐活性的抑制剂。 因此,这些化合物可用于治疗由依赖于白藜芦醇的铁采集系统的微生物引起的感染。 还提供了使用这些化合物治疗或预防感染的药物组合物和方法以及制备本发明化合物的方法。

    • In certain embodiments, the invention provides methods for treating cancer, comprising: (a) obtaining a specimen of cancer tissue and normal tissue from a patient; (b) extracting total protein and RNA from the cancer tissue and normal tissue; (c) obtaining a protein expression profile of the cancer tissue and normal tissue; (d) identifying over-expressed proteins in the cancer tissue; (e) comparing the protein expression profile to a gene expression profile; (f) identifying at least one prioritized protein target by assessing connectivity of each said over-expressed protein to other cancer-related or stimulatory proteins; (g) designing a first RNA interference expression cassette to modulate the expression of at least one gene encoding the prioritized target protein; (h): designing a first RNA interference expression cassette to modulate the expression of at least one gene encoding a protein of higher priority in the signaling pathway in which the first protein is a component; (i) incorporating the first cassette into a first delivery vehicle; (j) providing a patient with an effective amount of the first delivery vehicle; (k) extracting total protein and RNA from the treated cancer tissue; (l) identifying over-expressed proteins in the treated cancer tissue; (m) designing a second RNA interference expression cassette to modulate the expression of a second prioritized protein in the treated tissue; (n) incorporating the second cassette into a second delivery vehicle; (o) providing the previously treated patient with an effective amount of the second delivery vehicle; (p) identifying a novel protein signal following prior treatment with protein specific knockdown; (q) identifying a gene mutation provided by gene sequencing/microarray on assessment of other protein signals; and (r) identifying of a novel protein signal as a result of determination of the gene mutation and assessment of other protein signals to, directly or indirectly, modify the expression (i.e., production) of such proteins.
