Use is provided of a compound of formula (I):
wherein
Z is C=O or a covalent bond;
Y is H or O(C1-C4)alkyl,
R1 and R2 are individually (C1-C4)alkyl or together with N are a saturated heterocyclic group,
R3 is ethyl or chloroethyl,
R4 is H or together with R3 is -CH2-CH2- or -S-, R5 is O(C1-C4)alkyl or H and R6 is O(C1-C4)alkyl or H with the proviso that when R4, R5, and R6 are H, R3 is not ethyl;
or a pharmaceutically acceptable salt thereof, for the manufacture of a medicament for use in: the treatment or prevention of cardiovascular pathologies e.g. atherosclerosis, thrombosis, myocardial infarction or stroke, inhibiting smooth muscle cell (SMC) proliferation associated with procedural vascular trauma, preventing or treating a cardiovascular or vascular indication in a mammal characterised by a decreased lumen diameter, or increasing the level of TGF-beta in a mammal, effective to elevate the level of TGF-beta to treat and/or prevent conditions such as atherosclerosis, thrombosis, myocardial infarction, and stroke. Useful compounds include idoxifene, toremifene or salts thereof. Further provided is a method for identifying an agent that elevates the level of TGF beta. Another embodiment of the invention is an assay or kit to determine TGF-beta in vitro. Also provided is a therapeutic method comprising inhibiting smooth muscle cell proliferation associated with procedural vascular trauma employing the administration of tamoxifen or structural analogs thereof, including compounds of formula (1).
提供了式 (I) 化合物的用途:
其中
Z 是 C=O 或共价键;
Y 是 H 或 O(C1-C4)烷基、
R1 和 R2 单独为 (C1-C4) 烷基或与 N 一起为饱和杂环基团、
R3 是乙基或氯乙基、
R4 是 H 或与 R3 一起是-CH2-CH2-或-S-,R5 是 O(C1-C4)烷基或 H,R6 是 O(C1-C4)烷基或 H,但当 R4、R5 和 R6 是 H 时,R3 不是乙基;
或其药学上可接受的盐,用于制造以下用途的药物治疗或预防心血管病变,如动脉粥样硬化、血栓形成、心肌梗塞或中风;抑制与程序性血管创伤相关的平滑肌细胞(SMC)增殖;预防或治疗哺乳动物以管腔直径减小为特征的心血管或血管适应症;或提高哺乳动物体内 TGF-beta 的水平,有效提高 TGF-beta 的水平以治疗和/或预防动脉粥样硬化、血栓形成、心肌梗塞和中风等疾病。有用的化合物包括依多昔芬、托瑞米芬或其盐类。本发明还提供了一种鉴定可提高 TGF beta 水平的制剂的方法。本发明的另一个实施方案是一种测定体外 TGF-beta 的检测方法或试剂盒。本发明还提供了一种治疗方法,包括通过施用他莫昔芬或其结构类似物(包括式(1)化合物)来抑制与程序性血管创伤相关的平滑肌细胞增殖。
