Synthesis of icariin from kaempferol through regioselective methylation and para-Claisen–Cope rearrangement

open access: yesBeilstein Journal of Organic Chemistry, 2015
The hemisynthesis of the naturally occurring bioactive flavonoid glycoside icariin (1) has been accomplished in eleven steps with 7% overall yield from kaempferol.

Protein Prenylation in Plant Stress Responses

open access: yesMolecules, 2019
Protein prenylation is one of the most important posttranslational modifications of proteins. Prenylated proteins play important roles in different developmental processes as well as stress responses in plants as the addition of hydrophobic prenyl chains

Cloning and characterisation of chlorophyll synthase from Avena sativa [PDF]

open access: yes, 2001
The chlorophyll synthase gene from oat (Avena sativa) was cloned and expressed in Escherichia coli. The deduced amino acid sequence consists of 378 amino acids including a presequence, of 46 amino acids.

Identification of the new prenyltransferase Ubi-297 from marine bacteria and elucidation of its substrate specificity

open access: yesBeilstein Journal of Organic Chemistry, 2022
Aromatic prenylated metabolites have important biological roles and activities in all living organisms. Compared to their importance in all domains of life, we know relatively little about their substrate scopes and metabolic functions. Here, we describe

Agonistic and antagonistic estrogens in licorice root (Glycyrrhiza glabra) [PDF]

open access: yes, 2011
The roots of licorice (Glycyrrhiza glabra) are a rich source of flavonoids, in particular, prenylated flavonoids, such as the isoflavan glabridin and the isoflavene glabrene.

Atorvastatin-mediated inhibition of prenylation of Rab27b and Rap1a in platelets attenuates their prothrombotic capacity and modulates clot structure

open access: yesPlatelets, 2023
Statins inhibit the mevalonate pathway by impairing protein prenylation via depletion of lipid geranylgeranyl diphosphate (GGPP). Rab27b and Rap1a are small GTPase proteins involved in dense granule secretion, platelet activation, and regulation.

Thematic review series: Lipid Posttranslational Modifications. Lysosomal metabolism of lipid-modified proteins

open access: yesJournal of Lipid Research, 2006
Much is now understood concerning the synthesis of prenylated and palmitoylated proteins, but what is known of their metabolic fate? This review details metabolic pathways for the lysosomal degradation of S-fatty acylated and prenylated proteins. Central

Statin treatment increases lifespan and improves cardiac health in Drosophila by decreasing specific protein prenylation. [PDF]

open access: yesPLoS ONE, 2012
Statins such as simvastatin are 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors and standard therapy for the prevention and treatment of cardiovascular diseases in mammals.

Indole Diketopiperazine Alkaloids from the Marine Sediment-Derived Fungus Aspergillus chevalieri against Pancreatic Ductal Adenocarcinoma

open access: yesMarine Drugs, 2023
A new prenylated indole diketopiperazine alkaloid, rubrumline P (1), was isolated along with six more analogues and characterized from the fermentation culture of a marine sediment-derived fungus, Aspergillus chevalieri, collected at a depth of 15 m near
