Nitrogenous sesquiterpenes from the Thai marine sponge Halichondria sp.
Abstract Five nitrogenous sesquiterpenes having an isonitrile [(−)-axisonitrile-3], a formamide [(+)-axamide-3, axamide-2 and (3S*,5R*,6R*,9R*)-3-formamido-1(10)-cadinene], and an amineExpand
Lycophlegmariols A-D: cytotoxic serratene triterpenoids from the club moss Lycopodium phlegmaria L.
The structures of these hitherto unknown lycopodium terpenoids were elucidated on the basis of spectroscopic analysis and showed inhibitory effects against MOLT-3 acute lymphoblastic leukemia (T-lymphoblast) with IC(50) of 14.7, 3.0 and 2.9 μM. Expand
Terpenoids from the roots of Drypetes hoaensis and their cytotoxic activities.
Seven terpenoids and twelve known compounds and vanillin were isolated from the dichloromethane extract of the roots of Drypetes hoaensis and the anticancer activity of nine of these compounds was investigated. Expand
