Abstract:

Volatile piperidine alkaloids are widespread compounds found in low amounts in coniferous species. Here, we investigated the variation of piperidine alkaloid chemistry of Norway spruce (Picea abies (L.) Karst.) in a provenance-type experiment. Volatile piperidine alkaloids were analysed from current-year mature needles of 12 geographical origins grown for 35 years at the same site. Results indicate that, despite long-lasting similar growth conditions, origins were still showing different alkaloid composition and concentrations, indicating solid genotype variation. The highest total piperidine

An efficient synthesis of naturally occurring 1,2- and 1,3-amino alcohol unit containing 2-substituted piperidine alkaloids and their analogues has been developed from l-pipecolinic acid. The protocol describes the regio- and stereoselective oxymercuration–demercuration of 2-alkenyl piperidines based on protecting groups to give piperidine alkaloids as a key step.

AbstractPiperidine alkaloids continue to challenge the synthetic community by featuring densely functionalized scaffolds that often require careful chemical orchestration. Streptazone A and abikoviromycin are small and highly functionalized piperidine alkaloids, both accommodating Michael acceptors and a labile epoxide. These moieties are loaded into a [4.3.0] bicyclic core also present in other structurally related natural products, including the well-known piperidine alkaloid streptazolin.

The piperidine ring is a widespread motif in several natural bioactive alkaloids of both vegetal and marine origin. In the last years, a diversity-oriented synthetic (DOS) approach, aimed at the generation of a library of piperidine-based derivatives, was developed in our research group, employing commercially available 2-piperidine ethanol as a versatile precursor. Here, we report the exploration of another ramification of our DOS approach, that led us to the stereoselective total synthesis of (–)-anaferine, a bis-piperidine alkaloid present in Withania somnifera extract.

<b><i>Background:</i></b> Piperidines are biogenic amines studied mainly in toxicology because they were initially found as alkaloids from peppers and insect venoms. Piperidines are also produced in the human body, and their actions seem to be related to wakefulness/sleep and other cognitive phenomena. Piperidines have been minimally characterized for therapeutic applications. In this context, 1-Boc-piperidine-4-carboxaldehyde (1-Boc-piperidine) is a piperidine-derivative molecule with no mechanism of action reported, although its uses include the synthesis of GPR119 se

The high availability of 2-pyridones and the possibility of their far-reaching functionalization additionally increased their values.

Abstract:

Alkaloids are nitrogenous compounds within heterocyclic rings grouped into pyrrolidine, piperidine, pyrrolizidine, indolizidine, and nor-tropane alkaloids. Nevertheless, the origin and biological properties of polyhydroxy alkaloids remain limited. Therefore, this article aims to review polyhydroxy alkaloid’ major source and pharmacological properties. Based on the literature, the major source of polyhydroxy alkaloids primarily originate from various plant families including Asteraceae, Araceae, Boraginaceae, Fabaceae, Convolvulaceae, Lamiaceae, Orchidaceae, Piperaceae, Poaceae, and Solanaceae.

Abstract:

The first synthesis of coniine, a neurotoxic piperidine alkaloid found in poison hemlock (Conium maculatum L.), was performed back in 1886 by Ladenburg. Since that time, numerous different approaches to the synthesis of this and related alkaloids (2-alkylpiperidines) have been developed. Nowadays, the enantioselective/specific synthesis of coniine is taken as a paradigm of the usefulness of new chiral synthetic methodologies. This review aims to summarize and systematize recent progress in the synthesis of coniine and related compounds.

Abstract:

Background. Cassia spectabilis is a flowering plant containing various metabolites that provide potential for pharmacological activities. The current study aimed to investigate the ethanolic and water extracts of C. spectabilis as cholinesterase inhibitor as one of the target treatments for Alzheimer’s disease. The chemical composition of the extracts was also studied to determine which components are responsible for the bioactivity. Methods. The cholinesterase inhibitory activity assay was carried out by the modified Ellman’s method against acetylcholinesterase (AChE) and butyrylcholinesteras
