  • Methods of treating diseases responsive to Induction of Apoptosis
    申请人:Kasibhatla Shailaja

    公开(公告)日:2005-01-06
    The present invention pertains to a method of treating, preventing or ameliorating a disease responsive to induction of the caspase cascade in an animal, comprising administering to the animal a compound which binds specifically to a Tail Interacting Protein Related Apoptosis Inducing Protein (TIPRAIP). The present invention also relates to screening methods useful for drug discovery of apoptosis inducing compounds. In particular, the screening methodology relates to using TIPRAIP as a target for the discovery of apoptosis activators useful as anticancer agents. The screening methods of the present invention can employ homogenous or heterogenous binding assays using purified or partially purified TIPRAIP; or whole cell assays using cells with altered levels of TIPRAIP. The invention also contemplates use of 3-(4-azidophenyl)-5-(3-chloro-thiophen-2-yl)-[1,2,4]-oxadiazole or a substituted 3-aryl-5-aryl-[1,2,4]-oxadiazole which bind TIPRAIP and can accordingly be used to raise antibodies useful for drug discovery. Alternatively, labeled 3-(4-azidophenyl)-5-(3-chloro-thiophen-2-yl)-[1,2,4]-oxadiazole (or a labeled substituted 3-aryl-5-aryl-[1,2,4]-oxadiazole) is used for competitive binding assays for drug discovery. Such assays afford high throughput screening of chemical libraries for apoptosis activators.
    本发明涉及一种用于治疗、预防或改善对Caspase级联诱导敏感的动物疾病的方法,包括向动物投药一种与尾部相互作用蛋白相关凋亡诱导蛋白(TIPRAIP)特异结合的化合物。本发明还涉及有用于药物发现凋亡诱导化合物的筛选方法。特别是,筛选方法涉及使用TIPRAIP作为靶标,以发现作为抗癌剂有用的凋亡激活剂。本发明的筛选方法可以采用使用纯化或部分纯化的TIPRAIP的均相或异相结合分析;或使用具有改变TIPRAIP水平的细胞的全细胞分析。本发明还考虑使用3-(4-偶氮苯基)-5-(3-氯噻吩-2-基)-[1,2,4]-噁二唑或结合TIPRAIP的取代3-芳基-5-芳基-[1,2,4]-噁二唑,可用于制备有用于药物发现的抗体。或者,标记的3-(4-偶氮苯基)-5-(3-氯噻吩-2-基)-[1,2,4]-噁二唑(或标记的取代的3-芳基-5-芳基-[1,2,4]-噁二唑)可用于药物发现的竞争结合分析。这种分析为化学文库的高通量筛选提供了凋亡激活剂。

    A method for inhibiting or preventing Salmonella invasion of the intestinal epithelium in a subject, the method comprising enterally administering to the subject a pharmaceutically effective amount of a fatty acid dissolved or suspended in a pharmaceutically acceptable carrier, wherein the fatty acid contains 10 to 30 carbon atoms, wherein the fatty acid is more particularly an unsaturated fatty acid containing 1-4 carbon-carbon double bonds and/or 1 or 2 carbon-carbon triple bonds, or the fatty acid is more particularly a cis-unsaturated fatty acid, or the fatty acid is more particularly a cis-2-unsaturated fatty acid having the formula: wherein n is an integer of 6-26, and the fatty acid optionally includes a second carbon-carbon double bond resulting from removal of two hydrogen atoms on adjacent carbon atoms.

    It has been found that esterification of a hydroxy-fatty acid by a lipase can be coupled with oleate hydratase (OHase) generation of that hydroxy-FA from an unsaturated FA with a cis C9-C10 double bond, e.g. oleic acid, in a single aqueous buffered reaction medium at low temperature,e.g. 30°C. A simple one-pot enzymatic method to produce fatty acid estolides from one or more triglycerides, e.g. starting from a natural plant oil, is thereby enabled in which the same lipase catalyses both the initial hydrolysis of triglyceride and the final esterification step.
