Naucleamides A-E, new monoterpene indole alkaloids from Nauclea latifolia.
Five new monoterpene indole alkaloids, naucleamides A-E (1-5), were isolated from the bark and wood of Nauclea latifolia, and the structures and relative stereochemistry were elucidated from theExpand
Halichonadins K and L, new dimeric sesquiterpenoids from a sponge Halichondria sp.
Two new structurally unique dimeric sesquiterpenoids, halichonadins K (1) and L (2), were isolated from an Okinawan marine sponge Halichondria sp. The structures of 1 and 2 were elucidated on theExpand
Enantioselective total synthesis of eudistomidins G, H, and I
Asymmetric first total synthesis of eudistomidins G, H, and I, tetrahydro-β-carboline alkaloids from the Okinawan marine tunicate Eudistoma glaucus, has been accomplished with theExpand
Synthesis of eudistomin D analogues and its effects on adenosine receptors.
Six analogues (1-6) of eudistomin D, a beta-carboline alkaloid from a marine tunicate Eudistoma olivaceum, were synthesized, and their affinity and selectivity for adenosine receptors A(1), A(2A),Expand
Subincanadines A-C, novel quaternary indole alkaloids from Aspidosperma subincanum.
TLDR
Three novel quaternary indole alkaloids with an unprecedented 1-azoniatricyclo have been isolated from the barks of Aspidosperma subincanum Mart, and the structures of 1-6 and the stereochemistry of1-3 were elucidated by spectroscopic data and chemical means. Expand
Petiolins A-C, phloroglucinol derivatives from Hypericum pseudopetiolatum var. kiusianum.
TLDR
Three new phloroglucinol derivatives possessing chromane skeleton, petiolins A and B and petiolin C, were isolated from aerial parts of Hypericum pseudopetiolatum var. Expand
Synthesis of hybrid molecules of caffeine and eudistomin D and its effects on adenosine receptors.
Four hybrid molecules (1 and 12-14) of caffeine and eudistomin D, a beta-carboline alkaloid from a marine tunicate, were synthesized, and their affinity and selectivity for adenosine receptors A(1),Expand
Petiolins D and E, phloroglucinol derivatives from Hypericum pseudopetiolatum var. kiusianum
- A new phloroglucinol derivative possessing citran skeleton, petiolin D (1), and a new chromone glucoside, petiolin E (2), were isolated from aerial parts of Hypericum pseudopetiolatum var.Expand
Brianodins A-D, briarane-type diterpenoids from soft coral Pachyclavularia sp.
Four new briarane-type diterpenoids, brianodins A-D ( 1- 4), were isolated from a soft coral, Pachyclavularia sp., and the structures and relative stereochemistry of 1- 4 were elucidated on the basisExpand
