Two new bioactive mono-THF Annonaceous acetogenins, annoglacins A and B, have been isolated from the fractionated ethanolic extracts of the leaves of Annona glabra, directing the fractionation with the brine shrimp lethality test (BST). Their structures were elucidated based on spectroscopic and chemical methods and the absolute stereochemistries were determined by the advanced Mosher ester method...
Two new bioactive bis-THF Annonaceous acetogenins, glabracins A (1) and B (2), and two previously known acetogenins, javoricin (3) and bullatanocin (4), have been isolated from the leaves of Annona glabra by activity-directed fractionation using the brine shrimp lethality test (BST). The structures of 1 and 2 were elucidated based on spectroscopic and chemical methods, and the absolute stereochemistries...
