  Four alkaloids: (R)-(+)-cryspine A 5, (R)-(+)-octahydroindolo[2,3-a]quinolizidine 8, (R)-(+)-harmicine 19 and (R)-(+)-desbromoarborescidine 22 were prepared via the asymmetric transfer hydrogenation reaction of a prochiral enamine (iminium salt). The enantiomeric excesses of the isolated alkaloids were determined from their 1H NMR spectra measured in the presence of (+)-(R)-tert-butylphenylphosphinothio(seleno)ic

  While chiral fused-ring tetrahydroisoquinoline (THIQ) and tetrahydro-β-carboline (THβC) scaffolds have attracted considerable interest due to their wide spectrum of biological activities, the synthesis of optically pure chiral fused-ring THIQs and THβCs remains a challenging task. Herein, a group of active imine reductases were identified to convert the imine precursors into the corresponding enantiocomplementary

  虽然手性稠环四氢异喹啉 (THIQ) 和四氢-β-咔啉 (THβC) 支架因其广泛的生物活性而引起了相当大的兴趣，但合成光学纯的手性稠环 THIQs 和 THβCs 仍然是一项具有挑战性的任务。本文鉴定了一组活性亚胺还原酶，将亚胺前体转化为具有高对映选择性和转化率的相应的对映互补稠环 THIQ 和 THβC，建立了一种从 2-芳基乙胺制备稠环生物碱的高效绿色化学酶法。

  Current issues in cancer research involve searching for novel anticancer compounds that can be used to regulate the cell cycle and lead to more effective treatments of tumors. In this study, it was hypothesized that possessing a cyclic alkaloid similar to harmine, arborescidines can disrupt the proliferative state of cancer cells and block the activity of topoisomerases. The antiproliferative activity of arborescidines A-C and their derivatives was evaluated in vitro against four human tumor cell lines: gastric adenocarcinoma, lung cancer, bladder carcinoma and leukemia. Assuming the mechanism of action by topoisomerase II binding model, the compounds possessing the greatest activity had nonpolar side-chain into hydrophobic binding region on the DNA/topo II complex.
