Rumphellaones B and C, new 4,5-seco-caryophyllane sesquiterpenoids from Rumphellan antipathies.
Two new 4,5-seco-caryophyllane sesquiterpenoids, rumphellaones B (1) and C (2), which were found to possess unprecedented γ-lactone moieties, were obtained from the gorgonian coral Rumphella antipathies. The structures of 1 and 2 were elucidated by spectroscopic methods and compound 2 was found to display modest inhibitory effects on the generation of superoxide anions and the release of elasta...
متن کاملNew Bergamotane Sesquiterpenoids from the Plant Endophytic Fungus Paraconiothyrium brasiliense.
Brasilamides K-N (1-4), four new bergamotane sesquiterpenoids; with 4-oxatricyclo (3.3.1.0 (2,7))nonane (1)and 9-oxatricyclo(4.3.0.0 (4,7))nonane (2-4) skeletons; were isolated from the scale-up fermentation cultures of the plant endophytic fungus Paraconiothynium brasiliense Verkley. The previously identified sesquiterpenoids brasilamides A and C (5 and 6) were also reisolated in the current w...
متن کاملThe seco-iridoid pathway from Catharanthus roseus
The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum of high-value pharmacological and insect-repellent activities. Vinblastine and vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels, leading to high market prices and poor availab...
متن کاملTotal synthesis of seco-lateriflorone
A convergent strategy toward the synthesis of lateriflorone (5) is described. Our approach is based on biosynthetic considerations and draws on a sequence of prenylation, oxygenation and Claisen reactions for the construction of chromenequinone 6, and a tandem Claisen/Diels–Alder reaction cascade for the synthesis of caged tricycle 7. Union of fragments 6 and 7 led to the synthesis of secolater...
متن کاملGuaianolide and seco-Guaianolide from Salvia nubicola (Lamiaceae)
Salvia is one of the famous genera of the family Lamiacea previously called Labiatae comprising about 800 species throughout the world [1]. Most of the members of this genus are known due to their biologically active chemical constituents specifically reported for anti-tumor activity [2]. A number of Salvia species are used in folk medicines. For example, S. cavaleriei is used for the treatment...
