参考标题:Design, Synthesis And Biological Evaluation Of Novel Quinazoline-2,4-Diones Conjugated With Different Amino Acids As Potential Chitin Synthase Inhibitors 作者:Nada A. Noureldin,Hend Kothayer,El-Sayed M. Lashine,Mohamed M. Baraka,Yanrong Huang,Bing Li,Qinggang Ji |发布日期:2018.5 摘要:Acetamido) Acids) (6 A-M), (7) Has Been Designed To Inhibit The Action Of Fungus Chitin Synthase Enzyme (Chs). The Synthesis Of The Designed Compounds Was Carried Out In Four Steps Starting From The Reaction Between 1-Methylquinazoline-2,4(1H,3H)-Dione And Ethyl Chloroacetate To Yield The Ethyl Acetate Derivative. This Ester Was Hydrolyzed To The Corresponding Carboxylic Acid Derivative That Was Then
