Six monosaccharide derivatives of rotenone were designed and synthesized to assess whether rotenone could become phloem mobile by the addition of a monosaccharide group. Phloem mobility experiments showed that only D-glucose conjugates exhibit phloem transport properties in castor bean (Ricinus communis L.) seedlings. Two D-glucose conjugates, 2-O-beta-D-glucopyranosyldemethylrotenone and 6'-O-beta-D-glucopyranosyldalpanol, had significantly obtained systemicity compared with that of rotenone, and 6'-O-beta-D-glucopyranosyldalpanol was more mobile than 2-O-beta-D-glucopyranosyldemethylrotenone. Coupling with a monosaccharide core is a reasonable method for conferring phloem mobility on insecticides, but phloem mobility is also affected by the parent molecule and the position of the monosaccharide.

The invention relates to a combination of syrosingopine and a mitochondrial inhibitor, e.g. metformin or oligomycin, and the use of the combination of syrosingopine and a mitochondrial inhibitor for the treatment of cancer and for achieving immunosuppression. The invention also relates to a fluorescence-based method for predicting syrosingopine sensitivity of a cancer cell.
Enhanced intracellular uptake in vitro by glucose-functionalized nanopesticides
Nanopesticides have been increasingly used in agriculture. To improve the uptake of the target organisms for nanopesticides, we designed a dual-ligand nanopesticide based on gold nanoparticles (Au NPs) as a carrier.
