Nine new alkaloids, melodinines M–U (1–9), and 11 known alkaloids were isolated from Melodinus suaveolens. The new structures were elucidated by extensive NMR and mass spectroscopic analyses and ...

Topsentin alkaloids and their derivatives were designed, synthesized, and characterized on the basis of NMR and mass spectroscopy. The antiviral activities against tobacco mosaic virus (TMV) and ...

Discussion . The present paper reports the antitumor activity of piplartine and piperine on mice transplanted with Sarcoma 180. Piplartine and piperine are alkaloid-amide components from Piper species ...

The most common alkaloid found in the plants was lysergic acid alpha-hydroxyethylamide (LAH). This alkaloid is one of the lysergic acid amides Hofman identified in his studies.

In most cases, however, only the end product is known and it is largely unclear how these substances are produced in plants. Ipecacuanha alkaloids occur in two distantly related plant species ...

Making a discovery with the potential for innovative applications in pharmaceutical development, a microbiology student has found a long sought-after fungus that produces effects similar to the ...

Numerous studies have indicated that the plasma membrane plays an important role in the development of resistance to anthracycline and vinca alkaloid drugs (pleiotropic resistance). We have ...
