New selective acetylcholinesterase inhibitors designed from natural piperidine alkaloids
(Elsevier B.V., 2005-07-01)
Five new piperidine alkaloids were designed from natural (-)-3-O-acetyl-spectaline and (-)-spectaline that were obtained from the flowers of Senna spectabilis (sin. Cassia spectabilis, Leguminosae). Two semi-synthetic ...

Electrospray ionization mass spectrometry screening of piperidine alkaloids from Senna spectabilis (Fabaceae) extracts: Fast identification of new constituents and co-metabolites
(2005-11-01)
The fragmentation pattern of a homologous series of piperidine alkaloids isolated from S. spectabilis was investigated using electrospray ionization tandem mass spectrometry (ESI-MS/MS). The ESI-MS and ESI-MS/MS analyses ...

Isolation, leishmanicidal evaluation and molecular docking simulations of piperidine alkaloids from Senna spectabilis
(Elsevier B.V., 2018-12-01)
Leishmaniasis is one of the most important neglected tropical diseases (NTDs) that are especially common among low-income populations in developing regions of Africa, Asia, and the Americas. Many natural products, particularly ...
Antimalarial activity of piperidine alkaloids from Senna spectabilis and semisynthetic derivatives
(Sociedade Brasileira de Química, 2014-10-01)
In our continuing work looking for new anti-infective lead compounds from Brazilian biomes, the two known piperidine alkaloids ( - )-cassine and ( - )-spectaline were isolated from the flowers of Senna spectabilis (syn. ...
7-Hydroxycassine: A new 2,6-dialkylpiperidin-3-ol alkaloid and other constituents isolated from flowers and fruits of senna spectabilis (Fabaceae)
(2013-04-02)
The phytochemical study of flowers and green fruits of Senna spectabilis furnished a new substituted 2,6-dialkylpiperidin-3-ol alkaloid, named (-)-7-hydroxycassine, along with five known piperidine alkaloids: (-)-cassine, ...
