in the development of macrocyclic amidinoureas (MCAs) as antifungal agents. The mechanistic investigation drove us to perform an in silico target fishing study, which allowed the identification of chitinases as one of their putative targets, with 1a showing a submicromolar inhibition of Trichoderma viride chitinase. In this work, we investigated the possibility to further inhibit the corresponding human
我们的研究小组长期致力于大环脒脲(MCA)作为抗真菌药物的开发。机制研究促使我们进行了一项计算机目标钓鱼研究,该研究将几丁质酶鉴定为假定的目标之一,其中1a显示对绿色木霉几丁质酶具有亚微摩尔抑制作用。在这项工作中,我们研究了进一步抑制与几种慢性炎症性肺部疾病有关的相应人类酶、酸性哺乳动物几丁质酶 (AMCase) 和壳三糖苷酶 (CHIT1) 的可能性。因此,我们首先验证了1a对AMCase和CHIT1的抑制活性,然后设计和合成了新的衍生物,旨在提高对AMCase的效力和选择性。其中,化合物3f因其活性特征及其有前景的体外ADME 特性而出现。通过计算机研究,我们还很好地了解了与目标酶的关键相互作用。
