[EN] CRYSTALLINE FORMS OF A PYRROLIDONE DERIVATIVE USEFUL IN THE TREATMENT OF ALZHEIMER'S DISEASE AND PREPARATION THEREOF [FR] FORMES CRISTALLINES D'UN DÉRIVÉ PYRROLIDONE UTILES DANS LE TRAITEMENT DE LA MALADIE D'ALZHEIMER ET PRÉPARATION DE CELLES-CI
苄氧基苯基部分是单胺氧化酶B(MAO-B),沙芬酰胺和司加吉林的高效,选择性和可逆抑制剂的常见结构。我们合成了在末端芳基单元上包含卤素取代基的4-(苄氧基)苯基和联苯-4-基衍生物。另外,我们修饰了胺基和联芳基连接单元之间的碳连接基。在合成的化合物中,12c作为竞争性抑制剂表现出最有效和选择性的MAO-B抑制作用(hMAO-B IC 50:8.9 nM;选择性比MAO-A高10,000倍)。另外,12c与著名的MAO-B抑制剂(例如司来吉兰,沙芬酰胺和sembragiline)相比,具有更高的MAO-B抑制活性和选择性。在MPTP诱发的帕金森氏病(PD)小鼠模型中,12c可显着保护酪氨酸羟化酶(TH)免疫阳性DAergic神经元,并减轻与PD相关的行为缺陷。这项研究表明,作为MAO-B抑制剂的特征结构可能为PD治疗药物的开发提供很好的见识。

The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof. The compounds of the invention inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.
[Object] To provide a compound which can be used for the treatment of a disease associated with fatty acid amide hydrolase (FAAH), particularly urinary frequency, urinary incontinence and/or overactive bladder.
[Means for solution] It is confirmed that a urea compound chemical-structurally characterized by having a piperidine or piperazine ring or a salt thereof has an excellent FAAH-inhibitory activity, and thus the present invention is completed. The urea compound or its pharmaceutically acceptable salt of the present invention can increase the effective bladder capacity and ameliorate the state of urinary frequency, and is therefore useful as an agent for treating urinary frequency, urinary incontinence and/or overactive bladder.
