methodology offers a mild approach to obtain a library of 2-amino-4H-pyrans with good yields and favorable function group tolerance. Moreover, molecular docking experiments have been carried out to investigate the possible mechanism of this enzyme-initiated one-pot reaction. In addition, eight compounds in the library have been chosen in order to evaluate the in vitro antitumor activities against three
已开发出一种简单,有效且环保的生物催化方法,可在一锅中通过醛,丙二腈和乙酰乙酸乙酯的串联多组分反应(MCR)来构建2-氨基-4H-吡喃。研究了脂肪酶在不同反应介质和其他实验条件下的催化活性。报道的方法学提供了一种温和的方法来获得2-氨基-4H-吡喃的文库,具有良好的收率和良好的官能团耐受性。此外,已经进行了分子对接实验以研究这种酶引发的一锅反应的可能机理。此外,已选择文库中的八种化合物以评估针对三种细胞系(A549,Hela和HepG2)的体外抗肿瘤活性。结果表明4v具有最强的抗肿瘤活性,在A549细胞中IC50为0.0517μM。
