The synthesis of two series of β-amino ketones containing a p-aminobenzoic acid moiety (TM-1 and TM-2) using a modified protocol of the Mannich reaction is reported. The molecular structures of a total of tweenty three new target compounds were characterized by 1H NMR, 13C NMR, ESI-MS and HR-MS. Subsequently, their antidiabetic activities were screened in vitro. The α-glucodase inhibition (α-GI) activity of compound 1e reached a remarkable level of 66.50%. The peroxisome proliferator-activated receptor (PPAR) relative activation activities of six compounds are above 80%, and in particular 2i displays an unprecedentedly high PPAR of 130.91%. The structure-activity relationships of the compounds were established. 2i is also subject to further in-depth investigation.
报道了使用改进的Mannich反应方案合成了包含对氨基苯甲酸部分的两种系列的β-氨基酮(TM-1和TM-2)。总共23个新目标化合物的分子结构通过1H NMR、13C NMR、ESI-MS和HR-MS进行了表征。随后,它们在体外进行了抗糖尿病活性筛选。化合物1e的α-葡萄糖苷酶抑制(α-GI)活性达到了显著的66.50%水平。六个化合物的过氧化物酶体增殖物激活受体(PPAR)相对激活活性均超过80%,其中特别是2i显示了前所未有的高PPAR值130.91%。建立了这些化合物的结构-活性关系。2i也正在进行更深入的研究。
