New rearranged clerodane diterpenes from Tinospora baenzigeri.
Baenzigeroside B, a new rearranged clerodane diterpene glucoside, was isolated from the stems of Tinospora baenzigeri. The aglycone of baenzigeroside B, baenzigeride B (isolated as its acetate), was found together with baenzigeride A, baenzigerosides A and B in the leaves of the same plant. Baenzigeride B and baenzigeroside B are the first examples of a new class of rearranged clerodane diterpe...
متن کاملTwo New Clerodane Diterpenes from Tinospora sagittata.
Two new clerodane-type diterpenes, tinosporins C (1) and tinosporins D (2) were isolated from the stems of Tinospora sagittata (Oliv.), together with three known ones, columbin (3), tinophylloloside (4), and tinospinoside D (5). The structures of these compounds were determined on the basis of spectroscopic data interpretation, with that of the absolute configuration of compound 1 was assigned ...
متن کاملBiological activities and cytotoxicity of diterpenes from Copaifera spp. Oleoresins.
Copaifera spp. are Amazonian species widely studied and whose oleoresins are used by local people for various medicinal purposes. However, a detailed study of the activity of the main phytochemical components of these oleoresins remains to be done. Here, we studied the cytotoxicity and in vitro anti-inflammatory effects of six diterpene acids: copalic, 3-hydroxy-copalic, 3-acetoxy-copalic, hard...
متن کاملThree new clerodane diterpenes from Polyalthia longifolia var. pendula.
Three new clerodane diterpenes, (4→2)-abeo-cleroda-2,13E-dien-2,14-dioic acid (1), (4→2)-abeo-2,13-diformyl-cleroda-2,13E-dien-14-oic acid (2), and 16(R&S)- methoxycleroda-4(18),13-dien-15,16-olide (3), were isolated from the unripe fruit of Polyalthia longifolia var. pendula (Annonaceae) together with five known compounds (4-8). The structures of all isolates were determined by spectroscop...
متن کاملNeo-clerodane diterpenes from the hallucinogenic sage Salvia divinorum.
Seven new neo-clerodane diterpenes, salvidivins A (2), B, (3), C (4), and D (5), salvinorins H (6) and I (7), and divinatorin [corrected] F (8), along with eight known neo-clerodane diterpenes, salvinorins A (1)-F, divinatorins A and B, and seven other constituents, were isolated from the hallucinogenic sage Salvia divinorum. The structures of 1-7 were elucidated on the basis of 2D NMR spectros...
