GC–MS of some lycorine‐type Amaryllidaceae alkaloids

Journal of Mass Spectrometry, 2021
AbstractThe search for novel bioactive compounds and the identification of known ones in the plant kingdom are a challenge for the scientists working in different fields of plant science. In the recent years, mass spectrometry is the most frequently applied method for analysis of complex mixtures of plant metabolites.

Lycorine alkaloids from Hymenocallis littoralis

Phytochemistry, 1995
From Hymenocallis littoralis, one new alkaloid, named littoraline, together with 13 known lycorine alkaloids and one lignan, were isolated. The structure and NMR assignments of this new alkaloid were determined by 1D and 2D NMR techniques. Littoraline showed inhibitory activity of HIV reverse transcriptase, and lycorine and haemanthamine showed potent ...

Lycorine structure-activity relationships

Phytochemistry, 1983
Abstract Twenty three lycorine derivatives and naturally occurring alkaloids, structurally related to lycorine, were tested for their ability to inhibit ascorbic acid biosynthesis in potato tubers. The following relationships between structure modification and activity were observed: (a) cleavage of the acetalic bonds on the dioxole ring had no ...

Synthesis and antiviral activity of lycorine derivatives

Journal of Asian Natural Products Research, 2020
There are no effective antiviral drugs to treat hand, foot, and mouth disease. In this study, a series of lycorine derivatives were synthesized and evaluated against enterovirus 71 and coxsackievirus A16 in vitro. Derivatives 7c-m with the phenoxyacyl group at the C-1 position showed higher efficacy and lower toxicity than lycorine.

Total Synthesis of (−)-Lycorine and (−)-2-epi-Lycorine by Asymmetric Conjugate Addition Cascade

Organic Letters, 2009
Total syntheses of (-)-lycorine and (-)-2-epi-lycorine were accomplished using chiral ligand-controlled asymmetric cascade conjugate addition methodology, which enables the formation of two C-C bonds and three stereogenic centers in one pot to give synthetically useful chiral cyclohexane derivatives.
