Ergot alkaloids, produced by the plant parasitic fungi Claviceps purpurea are important pharmaceuticals. The chemistry, biosynthesis, bioconversions, physiological controls, and biochemistry have been extensively reviewed by earlier authors. We present here the research done on the organic synthesis of the ergot alkaloids during the past two decades. Our aim is to apply this knowledge to the sy...

Amaryllidaceae is a well-known family for its high alkaloidal content. These alkaloids comprise a unique group of bases that have been found to occur in this family. The Amaryllidaceae alkaloids represent a large and still expanding group of isoquinoline alkaloids, the majority of which are not known to occur in any other family of plants. This article reports on the phytochemical investigation...

The potential induction of a programmed cell death (PCD) in Trypanosoma b. brucei by 55 alkaloids of the quinoline, quinolizidine, isoquinoline, indole, terpene, tropane, steroid, and piperidine type was studied by measuring DNA fragmentation and changes in mitochondrial membrane potential. For comparison, the induction of apoptosis by the same alkaloids in human leukemia cells (Jurkat APO-S) w...

Pilocarpus microphyllus (Rutaceae), popularly known as jaborandi, is the only commercial source of an imidazole alkaloid named pilocarpine. In the present study, the variation in the profile of imidazole alkaloids in different seasons and in different parts of the P. microphyllus plant during the summer was analyzed by electrospray ionization mass spectrometry in the positive ion mode [ESI(+)-M...
