Webb27 jan. 2024 · All the alkaloids were in vitro evaluated for their cytotoxic activities against six glioma cell lines (CHG - 5, SH-SY5Y, SHG - 44, U251, U343, and GL15). Alkaloids 2 and 3 exhibited significant cytotoxic activities against all tested cell lines with IC 50 values of less than 20 μM. KEYWORDS: WebbTotal synthesis of the plicamine‐type alkaloids zephycarinatines C and D has been achieved. The key feature of the synthesis is a stereoselective radical ipso‐cyclization using visible‐light‐mediated photoredox catalysis.

Webb1 maj 2024 · Seven undescribed Amaryllidaceae alkaloids classified into four types, including the plicamine-type, secoplicamine-type, belladine-type and pretazettine-type, along with another three alkaloids that have not been isolated from plant material and seven known alkaloids, were isolated from the bulbs of Hymenocallis littoralis (Jacq.) … Webb28 apr. 2013 · Ghosal et al. recognised 12 distinct ring types when reviewing the alkaloids of the genus Crinum , a classification also followed by Evidente and Kornienko . Unver introduced two new subgroups called the graciline-type and the plicamine-type, the latter containing two nitrogen atoms . WebbAmaryllidaceae alkaloids have been isolated in more than 40 wild species and over 100 cultivars. The most common alkaloids in Narcissus species are lycorine- and homolycorine-types; notably, they do not contain crinine-type alkaloids, as they synthesise alkaloids with the 5,10b-ethano bridge in an α, not β position [8]. employment agency southfield mi
