C19-Norditerpenoid Alkaloids from Aconitum szechenyianum and Their Effects on LPS-Activated NO Production.
Three new C19-norditerpenoid alkaloids (1-3), along with two known C19-norditerpenoid alkaloids (4-5) have been isolated from Aconitum szechenyianum. Their structures were established by extensive spectroscopic techniques and chemical methods as szechenyianine A (1), szechenyianine B (2), szechenyianine C (3), N-deethyl-3-acetylaconitine (4), and N-deethyldeoxyaconitine (5). Additionally, compo...
متن کاملAnticancer Activities of C18-, C19-, C20-, and Bis-Diterpenoid Alkaloids Derived from Genus Aconitum.
Cancer is one of the most common lethal diseases, and natural products have been extensively studied as anticancer agents considering their availability, low toxicity, and economic affordability. Plants belonging to the genus Aconitum have been widely used medically in many Asian countries since ancient times. These plants have been proven effective for treating several types of cancer, such as...
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 کاملIn 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-...
