A series of novel berberine derivatives, 4,7,12,12a-tetrahydro-5H-thieno[3′,2’:3,4]pyrido[1,2-b]isoquinolines was designed, synthesized, and biologically evaluated for their anti-diabetic activity. Following the evaluation in two types of cells, compounds 4aa, 4bq, and 4bv stimulated glucose consumption (1.8- to 2.3-fold), reduced gluconeogenesis (60–85%), inhibited mitochondria respiratory chain complex
设计,合成了一系列新颖的小ber碱衍生物4,7,12,12a-tetrahydro-5 H -thieno [3',2':3,4]吡啶[1,2- b ]异喹啉,并对其进行了生物学评估他们的抗糖尿病活性。在两种类型的细胞中进行评估后,化合物4aa,4bq和4bv刺激了葡萄糖消耗(1.8到2.3倍),糖异生减少(60-85%),抑制了线粒体呼吸链复合体I并间接激活了AMPK。在db / db小鼠模型中,化合物4bq和4bv以120 mg / kg /天的剂量降低了空腹血糖。此外,化合物4bq和与小ber碱相比,发现4bv具有改善的药代动力学特征(生物利用度分别为45和106%)。化合物4bq和4bv没有表现出明显的hERG抑制作用(IC 50 > 10μM)。
