The Analyst, 1937
The article on ergot in this Handbook (vol. II, 2, pp. 1297–1354) was written by Arthur Cushny in 1914 but not published until 1924, without further revision. Thus a gap of more than two decades has now to be filled. In this interval the number of known ergot alkaloids has increased from two to eleven or twelve, all crystalline, and a considerable ...

The manzamine alkaloids are absolutely one of the most fascinating marine natural products. The representative manzamine alkaloids, manzamines A-C, were isolated from a marine sponge Haliclona sp. collected off Cape Manzamo, Okinawa, Japan. The manzamine alkaloids are a unique class of alkaloids possessing a characteristic heterocyclic system, and ...

The Cylindrospermopsin Alkaloids
2011Abstract The cylindrospermopsin alkaloids are a family of structurally similar toxic natural products first encountered with the isolation of cylindrospermopsin from the cyanobacterium Cylindrospermopsis raciborskii , which was the causative agent in the poisoning of 148 inhabitants of Palm Island, Australia.

Securinega alkaloids represent a family of plant secondary metabolites known for 50 years. Securinine (1), the most abundant and studied alkaloid of this series was isolated by Russian researchers in 1956. In the following years, French and Japanese scientists reported other Securinega compounds and extensive work was done to elucidate their intriguing

Iboga alkaloids are a particular class of indolomonoterpenes most often characterized by an isoquinuclidine nucleus. Their first occurrence was detected in the roots of Tabernanthe iboga, a sacred plant to the people of Gabon, which made it cult object.

Naturally occurring pyrrolizidine alkaloids (PAs) are isolated from plants and other sources. The interest of the scientific community in these compounds owes itself to their high toxicity and biological activity, as well as to the challenge of synthesizing their pyrrolizidine scaffold.

Plant Alkaloids: The Vinca Alkaloids
1989Although a large number of compounds from a wide variety of plants have been tested for antitumor activity, none has played a more vital role in cancer chemotherapy than the vinca alkaloids. These compounds are present in minute quantities in the plant Catharanthus roseus G. Don (Vinca rosea Linn.), commonly called the periwinkle.
