  • NOVEL ANTI-INFLAMMATORY COMPOUNDS
    申请人:The University of Tokyo
    公开号:EP2415748A1
    公开(公告)日:2012-02-08
    An object of the present invention is to provide a compound having a novel structure for overcoming the defects of conventional steroid agents and NSAIDs. It is found that the particular dihydroxy bodies of eicosapentaenoic acid and docosahexaenoic acid, which have not conventionally been known (11,18-dihydoxy eicosapentaenoic acid (11,18-diHEPE), 17,18-dihydroxy eicosapentaenoic acid (17,18-diHEPE) etc.), have activity of inhibiting neutrophil, thereby solving the object. The present invention unexpectedly remarkably inhibits infiltration into a tissue of, and activation of neutrophil found out at acute inflammation. The compound of the present invention is a compound which has not conventionally been known. Therefore, utility as a new therapeutic is provided.
    本发明的目的是提供一种具有新型结构的化合物,以克服传统类固醇制剂和非甾体抗炎药的缺陷。本发明发现,传统上未知的二十碳五烯酸和二十二碳六烯酸的特定二羟基体(11,18-二羟基二十碳五烯酸(11,18-diHEPE)、17,18-二羟基二十碳五烯酸(17,18-diHEPE)等)具有抑制中性粒细胞的活性,从而解决了上述目的。本发明意外地显著抑制了急性炎症时发现的中性粒细胞对组织的浸润和活化。本发明的化合物是一种传统上不为人所知的化合物。因此,本发明可作为一种新疗法使用。
  • Coversin variants lacking C5 binding

    公开号:US11214602B2
    公开(公告)日:2022-01-04
    The invention is directed to modified Coversin polypeptides which exhibit leukotriene or hydroxyeicosanoid binding activity and reduced or absent C5 binding relative to the unmodified Coversin polypeptide; to nucleic acid molecules encoding said modified Coversin polypeptides; vectors and host cells comprising said nucleic acid molecules; and methods of treating or preventing diseases or conditions mediated by a leukotriene or hydroxyeicosanoid in a subject comprising administering said modified polypeptides or nucleic acids to a subject.
    本发明涉及修饰的Coversin多肽,与未修饰的Coversin多肽相比,修饰的Coversin多肽具有白三烯或羟基平二缩酮结合活性,且C5结合活性降低或消失;涉及编码所述修饰的Coversin多肽的核酸分子;包含所述核酸分子的载体和宿主细胞;以及治疗或预防受试者中由白三烯或羟基叶酸介导的疾病或病症的方法,包括对受试者施用所述修饰的多肽或核酸。
  • Assays for screening activity of modulators of members of the hydroxy steroid (17-beta) dehydrogenase (HSD17B) family
    申请人:Regeneron Pharmaceuticals, Inc.
    公开号:US11479802B2
    公开(公告)日:2022-10-25
    Screening methods as well as kits for identifying modulators of hydroxysteroid (17-beta) dehydrogenase (HSD17B) family member proteins, such as HSD17B13, are provided. The methods comprise screening molecules for their capacity to modulate the HSD17B family member protein, including inhibiting the HSD17B family member protein, as measured by substrate depletion, product concentration from the HSD17B family member protein substrate conversion or NADH concentration, levels of labeled substrate, luciferin light emission, or combinations thereof. Inhibitors of HSD17B family member proteins identified through the screening methods may be used to treat liver diseases, disorders, or conditions in which the HSD17B family member protein plays a role.
    本发明提供了用于鉴定羟基类固醇(17-beta)脱氢酶(HSD17B)家族成员蛋白(如 HSD17B13)调节剂的筛选方法和试剂盒。这些方法包括筛选分子,以确定其调节 HSD17B 家族成员蛋白的能力,包括抑制 HSD17B 家族成员蛋白的能力,通过底物耗竭、HSD17B 家族成员蛋白底物转化产物浓度或 NADH 浓度、标记底物水平、荧光素发光或其组合来测量。通过筛选方法鉴定的 HSD17B 家族成员蛋白的抑制剂可用于治疗 HSD17B 家族成员蛋白起作用的肝脏疾病、失调或病症。

    Methods, systems and equipment for diagnosing renal cell carcinoma (RCC) and other solid tumors. This invention identifies numerous disease genes that are differentially expressed in the peripheral blood of patients having RCC or other solid tumors relative to disease-free humans. These disease genes can be used as surrogate markers for detecting the presence or absence of RCC or other solid tumors.
    诊断肾细胞癌(RCC)和其他实体瘤的方法、系统和设备。本发明确定了许多疾病基因,这些基因在 RCC 或其他实体瘤患者的外周血中相对于无病人类有不同的表达。这些疾病基因可用作替代标记物,用于检测是否存在 RCC 或其他实体瘤。
