Dimeric sesquiterpene thioalkaloids from the rhizomes of Nuphar pumilum exhibited immunosuppressive effects using a sheep erythrocyte plaque forming cell (PFC) assay, as well as an anti-metastasis effect, and rapid apoptosis-inducing effects in tumor

An eight step, asymmetric synthesis of a dimeric thiaspirane nuphar alkaloid from 3-methyl-2-cyclo-pentenone is reported. The brevity of the route relies on a useful procedure for tandem reductive allylation of cyclopentenones, as well as the minimiz

Electron ionization of sulphur-containing Nuphar alkaloids leads to the formation of easily detectable, doubly-charged species. The study of charge-separation reactions by collision experiments allows us to determine the intercharge distances. These

The coulometric titration technique is applied for evaluation of protonation constants of substances available in micromolar amounts. The validity of the procedure was checked by studying several well-known systems. Unknown constants were evaluated f
