G. Shi et al., ROLLINECIN-A AND ROLLINECIN-B - 2 NEW BIOACTIVE ANNONACEOUS ACETOGENINS FROM ROLLINIA-MUCOSA, Journal of natural products, 59(5), 1996, pp. 548-551
Two new mono-THF ring acetogenins, rollinecins A (1) and B (2), were i
solated from the partitioned ethanolic extracts of the leaves of Rolli
nia mucosa (Annonaceae) by activity-directed fractionation. 1 and 2 ar
e epimeric at the C-14 carbinol stereocenter. Their absolute stereoche
mical structures were solved by preparing their respective per-Mosher
ester derivatives. 1 and 2 showed equivalent and selective in vitro ac
tivities against several human solid tumor cell lines.
