寻找能有效抑制肝脏胰高血糖素反应的新型抗糖尿病化合物是开发抗糖尿病新药的迫切需要。真菌以其产生新的生物活性次生代谢物的能力而闻名。作为我们正在进行的研究的一部分,从真菌青霉中分离到五个新的吲哚-萜类化合物(1-5),命名为Enindolenes D-H。从白首乌根际土壤中提取的HFF16。化合物的结构经波谱数据和电子捕获分析确证。在抗糖尿病活性实验中,化合物1-5能抑制肝糖的产生,EC50值分别为17.6、30.1、21.3、9.6和9.9μM,并能降低高血糖素诱导的细胞内cAMP含量。
Finding novel anti-diabetic compounds with effective suppression activities against hepatic glucagon response is urgently required for the development of new drugs against diabetes. Fungi are well known for their ability to produce new bioactive secondary metabolites. As part of our ongoing research, five new indole-terpenoids (1–5), named encindolenes D-H, were isolated from the fungus Penicillium sp. HFF16 from the rhizosphere soil of Cynanchum bungei Decne. The structures of the compounds were elucidated by spectroscopic data and ECD analysis. In the anti-diabetic activity assay, compounds 1–5 could inhibit the hepatic glucose production with EC50 values of 17.6, 30.1, 21.3, 9.6, and 9.9 μM, respectively, and decrease the cAMP contents in glucagon-induced HepG2 cells.
