In vitro cytotoxicity of norditerpenoid alkaloids.
Forty-three norditerpenoid alkaloids isolated from Aconitum, Delphinium and Consolida species have been evaluated for their cytotoxic effects on the tumor cell lines CT26 (murine colon adenocarcinoma), SW480 (human colon adenocarcinoma), HeLa (human cervical adenocarcinoma), SkMel25 (human melanoma) and SkMel28 (human malignant melanoma) with several multidrug resistance mechanisms and the non-...
متن کاملNorditerpenoid alkaloids from Delphinium kohatense Munz
A new aconitine-type norditerpenoid alkaloid, kohatenine (1) [10β-hydroxy-1α,8β,16β-trimethoxy6α,14α-diacetyl-N-ethyl aconitane], along with four known alkaloids, condelphine (2), talatisamine (3), peregrine (4), and 14-O-acetyltalatisamine (5), was isolated from the aerial parts of Delphinium kohatense Munz. The structure of the new compound was deduced on the basis of combined MS (EI and FAB)...
متن کاملNorditerpenoid alkaloids from Delphinium flexuosum Bieb.
Delphiniflexine, a new norditerpenoid alkaloid, together with the three known norditerpenoid alkaloids methyllycaconitine, ajadine, and acoseptrigenine were isolated from the aerial parts of Delphinium flexuosum. The structure of delphiniflexine was established on the basis of 1H, 13C, DEPT, homonuclear 1H COSY, NOESY, HSQC, and HMBC NMR studies.
متن کاملNew norditerpenoid alkaloids from Scutellaria barbata with cytotoxic activities.
Two new norditerpenoid alkaloids, named scutebarbatines M-N (1 and 2), were isolated from the whole plant of Scutellaria barbata D. Don. Their structures were established on the basis of detailed spectral analyses. In vitro, two new compounds showed significant cytotoxic activities against three human cancer lines (HONE-1 nasopharyngeal, KB oral epidermoid carcinoma and HT29 colorectal carcinom...
متن کاملCytotoxicity of the beta-carboline alkaloids harmine and harmaline in human cell assays in vitro.
beta-Carboline alkaloids are natural products widely distributed in plants and also found in alcoholic beverages, well-cooked foods and tobacco smoke. Various authors have reported genotoxic activities of several carboline in prokaryotic and eukaryotic cells that have been attributed to their abilities to intercalate into DNA. But studies on the genotoxic and on the cytotoxic potencies in human...
