of amiloride. Reductions in lung metastases were demonstrated for two analogs in a late-stage experimental mouse metastasis model, and one analog completely inhibited formation of liver metastases in an orthotopic xenograft mouse model of pancreatic cancer. The results support further evaluation of 6-substituted HMA derivatives as uPA-targeting anticancer drugs.
转移是大多数(约90%)恶性肿瘤的死亡原因。口服保钾利尿剂阿米洛利及其5取代衍生物5 -N,N据报道,在多种体外和动物模型中,(六亚甲基)阿米洛利(HMA)显示出强大的抗肿瘤/转移作用。这些作用可能至少部分是由于抑制了尿激酶纤溶酶原激活剂(uPA),尿激酶纤溶酶原激活剂(uPA)是细胞侵袭和转移的关键蛋白酶决定因素。这项研究报告发现了6个取代的HMA类似物,这些类似物显示出对uPA的纳摩尔效价,对相关胰蛋白酶样丝氨酸蛋白酶的高选择性以及对上皮钠通道(ENaC),阿米洛利的利尿剂和抗钾尿素靶标的最小抑制作用。在晚期实验性小鼠转移模型中证明了两种类似物的肺转移减少,而在胰腺癌的原位异种移植小鼠模型中,一种类似物完全抑制了肝转移的形成。
