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 ...

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.

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
