Inhibitors of glycolic acid oxidase. 4-Substituted-2,4-dioxobutanoic acid derivatives
摘要:
Fourteen new 4-substituted 2,4-dioxobutanoic acids have been synthesized. These compounds, all of which contain lipophilic 4-substituents, are potent inhibitors in vitro of porcine liver glycolic acid oxidase. The I50 value of the two most potent representatives, 4-(4'-bromo[1,1'-biphenyl]-4-yl)-2, 4-dioxobutanoic acid (8) and 4-[4'-[[(3,4-dihydro-3-hydroxy-2H-1, 5-benzodioxepin-3-yl)methyl]thio][1,1'-biphenyl]-4-yl]-2, 4-dioxobutanoic acid (13) is 6 X 10(-8)M.

An unprecedented organocatalytic, regioselective, modified Guareschi–Thorpe type protocol toward the modular synthesis of 5,6,7,8-tetrahydroquinolines 22a–g and other alicyclic[b]-fused pyridines 23–28 via the identification of Chitosan as a heterogeneous catalyst is reported. This novel strategy is operationally simple and showed a wide range of functional group tolerance and substrate compatibility
前所未有的有机催化,区域选择性,改良的Guareschi-Thorpe型方案,通过鉴定壳聚糖作为多相催化剂,可模块化合成5,6,7,8-四氢喹啉22a – g和其他脂环式[ b ]稠合吡啶23 – 28。被报道。这种新颖的策略操作简单,并且具有广泛的官能团耐受性和底物相容性。拟议的机制途径涉及亚胺-烯胺级联方法,用于合成结构多样的脂环式[ b ]稠合吡啶杂环。新型抗真菌分子的克级合成和鉴定29 –图31强调了这种方法的实用性。
