及其药学上可用的衍生物、溶剂化物、盐和立体异构体,包括其全部比率的混合物。
优选,式I化合物显示作为vanin抑制剂的活性。
发明背景:
术语"vanin抑制剂"在本文中优选定义为化合物,其在体外和/或在体内:(i)抑制Vanin-1的活性和/或表达;和/或(ii)阻断泛酰巯基乙胺转化为半胱胺和泛酸;和/或(iii)阻断半胱胺和/或胱胺即半胱胺氧化式的细胞内合成。抑制和阻断可以是完全或部分的。
Vanin-1和Vanin-3,优先地分别通过上皮和髓性细胞表达(Martin,2001)。在人类和果蝇属中,该酶通过3种基因(VNN-1,VNN-2,VNN-3)编码。在小鼠和人类中,Vanin-1和VNN1分别GPI-固定至细胞膜和在各种上皮细胞的刷状边界高度表达,所述上皮细胞包括肠上皮细胞、肾管细胞、肝细胞、胰腺泡细胞、胸腺骨髓上皮细胞(Galland,1998;Aurrand-Lions,1996;Pitari,2000;Martin,2001)。在果蝇属中,鉴定出与哺乳动物Vanin序列同源的4种基因,并且初步研究显示果蝇属具有泛酰巯基乙胺酶活性(Granjeaud et al,1999)。
Vanin-1缺乏的小鼠正常发展,但不具有可检测的肾和肝中游离(半)胱胺,尽管存在Vanin-3(Pitari,2000)。
Vanin-1基因的灭活预防急性和慢性炎症,原因是在两种情况下在Vanin-1缺乏的小鼠中的肠伤害与对照相比均较温和。这种保护与炎性分子、髓性细胞募集和肠粘膜损害的降低表达有关。另外,谷胱甘肽合成和贮藏在肝和肠中增加(US 2004/0247524)。这些事件进一步显示与缺少游离的半胱胺/胱胺有关,其在Vanin-1缺乏的小鼠中是不可检测的,原因是经口提供的胱胺逆转炎性表型。该逆转效果与体内的谷胱甘肽合成的抑制相关。从而,显示作为vanin抑制剂的显著活性的式I化合物可用于治疗炎性病症。
如本文所用,"炎性病症"表示持续或慢性炎症的状况,其在组织被病毒、细菌、创伤、化学品、热、冷或任意其它有害刺激损伤时发生。优选,根据本发明的炎性病症是胃肠道炎性病症,其可以选自炎性肠病(IBD)比如肠易激综合征(IBS),溃疡性结肠炎和克罗恩病,给药非甾族抗炎性药物导致的溃疡比如消化性溃疡(也即胃或十二指肠粘膜中形成的溃疡),和与曼森氏裂体吸虫(Schistosoma mansoni)寄生物感染有关的炎性病症。
术语"治疗"或"处理"意指对障碍的预防性或治疗性治疗,也即逆转、减轻、抑制该术语限定的障碍或病症或所述障碍或病症的一种或多种症状的进程,或者预防该术语限定的障碍或病症或所述障碍或病症的一种或多种症状。治疗可以与又一预先存在的治疗关联以改善所述预先存在的治疗的效力。
