摘要: 从6-羟基托品酮出发,经过羟基的乙酰基化和苯甲酰基化,再通过还原氨化高效地得到含有活泼胺基的2个母核化合物。 2个母核化合物与不同的酰氯反应,得到一系列托品酮衍生物。 该衍生物经过体外过氧化物酶增生因子活化受体γ亚型(PPARγ)激活、二肽基肽酶Ⅳ (DPP-Ⅳ)抑制实验,发现多数化合物对DPP-Ⅳ显示抑制活性,其中2个化合物(3 μmol/L DMSO溶液)对DPP-Ⅳ抑制率超过30%。

Abstract: 6-Hydroxytropinone was chosen as the primary precursor and subjected to a series of reactions including acetylation or benzoylation of its hydroxyl group, reduction and ammoniation of its keto group to yield two compounds containing tropane with primary amine core structure. A series of N-acyl compounds has been prepared by the reactions of the core structures with a variety of acyl chlorides. These compounds were screened in peroxisome proliferateive activeated recaptor-γ(PPARγ) and dipeptidylpeptidase-Ⅳ(DPP-Ⅳ) in-vitro models. Most of these compounds displayed inhibitory effect against DPP-Ⅳ and two of them showed inhibitory rates higher than 30% at 3 μmol/L in DMSO. But no activation toward PPARγ of all compounds could be observed.

Key words: tropinone derivaties, diabetes, In-vitro model, dipeptidylpeptidase-IV inhibitory effect
