An investigation of the Guyana plant Simarouba amara Aubl. (Simaroubaceae) for antineoplastic quassinoids led to isolation and structural determination of the new quassinoids 2'-acetylglaucarubine (1a) and 13,18-dehydroglaucarubinone (2). The previously known 2'-acetylglaucarubinone (3a) and
OBJECTIVE
The objective of this study was to evaluate the cytotoxic and anticancer activities of extracts from 7-species of endemic and native plants from Puerto Rico.
METHODS
The plant species selected for this study were Canella winterana, Croton discolor, Goetzea elegans, Guaiacum officinale,
Species of the genus Simarouba have been studied because of their antimalarial and antileukemic activities. A group of oxygenated terpenes called quassinoids have been isolated from species of the Simarouba genus, and are responsible for its therapeutic properties. We hypothesized that
beta-Sitosterol, epilupeo, amarolide-11-acetate, amarolide-2,11-diacetate, ailanthinone and glaucarubinone have been isolated from S. versicolor. The cytotoxic and antileukemic activities of extracts of this plant are due chiefly to glaucarubinone.
The search for new anti-cancer drugs is one of the most prominent research areas of natural products. Numerous active compounds isolated from Brazilian Cerrado plant species have been studied with promising results.
OBJECTIVE
To investigate the cytotoxic potential of 412 extracts from Brazilian
Emerging advancements in anticancer drug discovery research are leaning towards the plant-based bioactive fractions, which is a cocktail of naturally abundant two or more substances with unique proportions, exhibiting greater potential to combat cancers than the individual molecules. Thus, isolation
While anticancer properties of Simarouba glauca (SG, commonly known as Paradise tree) are well documented in ancient literature, the underlying mechanisms leading to cancer cell death begin to emerge very recently. The leaves of SG have been used as potential source of anticancer agents in
