progression of many types of cancer is well acknowledged, and more recently human monoamineoxidases (hMAOs) A and B have been found important contributors to tumor development and aggressiveness. With a view of an enzymatic dual-blockade approach, in this investigation, new coumarin-based amino acyl and (pseudo)-dipeptidyl derivatives were synthesized and firstly evaluated in vitro for inhibitory activity and
人碳酸酐酶 (hCA) IX/XII 在许多类型癌症的发病机制和进展中的作用已得到公认,最近发现人单胺氧化酶 (hMAO) A 和 B 对肿瘤的发展和侵袭性具有重要贡献。鉴于酶促双重阻断方法,在本研究中,合成了新的基于香豆素的氨基酰基和(假)-二肽基衍生物,并首先在体外评估了对膜结合和胞质 hCAs 的抑制活性和选择性(hCA IX /XII 超过 hCA I/II) 以及 hMAO,以估计它们作为抗癌剂的潜力。从头开始随后进行了肽-香豆素缀合物的设计,涉及将广泛探索的香豆素核与天然或修饰肽的独特生物物理和结构特性相结合。所有化合物都显示出对膜锚定 hCA 的纳摩尔抑制活性,同时它们无法阻断普遍存在的 CA I 和 II 亚型。讨论了与有效和选择性 CA 抑制活性相关的结构特征,并发现建模研究支持生物学数据。观察到 hMAO 的较低效力抑制,大多数化合物显示出对 hMAO-A 的优先抑制。最有效的配体(6和16)

The synthesis and biological activity of analogues containing spiro piperidinylpyridine and pyrrolidinylpyridine templates are described. The potent activity of these compounds as platelet aggregation inhibitors demonstrates the utility of the spiro structures as central template for nonpeptide RGD mimics.
