Synthesis and Biological Evaluation of Thieno[3,2-d]- pyrimidinones, Thieno[3,2-d]pyrimidines and Quinazolinones: Conformationally Restricted 17b-Hydroxysteroid Dehydrogenase Type 2 (17b-HSD2) Inhibitors

2-d]pyrimidines and quinazolinones was designed and synthesized with the goal of improving the biological activity as 17β-hydroxysteroid dehydrogenase type 2 inhibitors of the corresponding amidothiophene derivatives. Two moderately active compounds were discovered and this allowed the identification of the biologically active open conformer as well as the extension of the enzyme binding site characterisation
本研究设计并合成了一系列构象受限的噻吩并[3,2-d]嘧啶酮、噻吩并[3,2-d]嘧啶和喹唑啉酮,目的是提高作为17β-羟基类固醇脱氢酶2型抑制剂的生物活性相应的酰氨基噻吩衍生物。发现了两种中等活性的化合物,这允许鉴定具有生物活性的开放构象异构体以及酶结合位点特征的扩展。
