O-Methyl Phytocannabinoids: Semi-synthesis, Analysis in Cannabis Flowerheads, and Biological Activity
Planta Med DOI: 10.1055/a-0883-5383A general protocol for the selective mono-O-methylation of resorcinyl phytocannabinoids was developed. The availability of semisynthetic monomethyl analogues of cannabigerol, cannabidiol, and cannabidivarin (1a–3a, respectively) made it possible to quantify these minor phytocannabinoids in about 40 different chemotypes of fiber hemp. No chemotype significantly accumulated mono-O-methyl cannabidiol (2b) or its lower homologue (3b), while at least three chemotypes containing consistent amounts (≥ 400 mg/kg) of O-methylcannabigerol (1b) were identified. O-Methylation o...

Current Methods for the Discovery of New Active Ingredients from Natural Products for Cosmeceutical Applications
Planta Med DOI: 10.1055/a-0857-6633Cosmeceuticals are designed to serve a dual purpose: to provide desired esthetical effects and to treat dermatological conditions. Natural products derived from plants and marine organisms are a novel source of potential cosmeceutical active ingredients for incorporation into new formulations due to consumer demands. Contrary to common perceptions, most regulatory agencies do not view cosmeceuticals as being a separate category from cosmetics; thus, these products are not regulated accordingly, thereby forcing the consumer to rely on the self-regulatory policies of the cosmetics industry....

Antiplasmodial Lycorane Alkaloid Principles of the Plant Family Amaryllidaceae
Planta Med DOI: 10.1055/a-0880-5414The spread of malaria is thought to have followed human expansion out of Africa some 60 – 80 thousand years ago. With its prevalence in pantropical countries of the world and epicenter localized in Africa, malaria is now considered an unnecessary burden to overworked and under-resourced healthcare structures. Plants have long afforded a fertile hunting ground for the search and identification of structurally diverse antimalarial agents, such as quinine and artemisinin. This survey examines the antiparasitic properties of the family Amaryllidaceae via the antiplasmodial activitie...

Structure-Activity Relationship of Transfection-Modulating Saponins – A Pursuit for the Optimal Gene Trafficker
Planta Med DOI: 10.1055/a-0863-4795 The ability of certain triterpenoid saponins to modulate the endosomal release during the process of endocytosis and to ensure a nontoxic and efficient transfection recently led to an exceptional interest in the field of nonviral gene delivery. In vitro and in vivo studies demonstrated promising results in terms of tumor growth inhibition after the delivery of a suicide gene such as saporin and dianthin. With that, the question arises which structural features are necessary or advantageous to achieve an effective endosomal escape. Former studies described certain important characteristic...

Magnesium Lithospermate B Derived from Salvia miltiorrhiza Ameliorates Right Ventricle Remodeling in Pulmonary Hypertensive Rats via Inhibition of NOX/VPO1 Pathway
This study aims to investigate whether MLB is able to prevent RV remodeling in PAH and the underlying mechanisms. In vivo, SD rats were exposed to 10% O2 for 21 d to induce RV remodeling, which showed hypertrophic features (increases in the ratio of RV weight to tibia length, cellular size, and hypertrophic marker expression), accompanied by upregulation in expression of NADPH oxidases (NOX2 and NOX4) and vascular peroxidase 1 (VPO1), increases in hydrogen peroxide (H2O2) and hypochlorous acid (HOCl) production and elevation in phosphorylation levels of ERK; these changes were attenuated by treating rats with MLB. I...

Neuroprotective Effects of Dammarane-Type Saponins from Panax notoginseng on Glutamate-Induced Cell Damage in PC12 Cells
Planta Med DOI: 10.1055/a-0853-7754Dammarane-type saponins, the main active ingredients of Panax notoginseng, have substantial neuroprotective effects in different animal models of neurodegenerative diseases. However, because these compounds have different structures, the level of protection provided by individual compounds varies, and highly active compounds can be selected based on structure-activity relationships. Glutamate is a major excitatory neurotransmitter that plays an important role in synaptic response development. However, excessive extracellular glutamate levels lead to neuronal dysfunctions in the central ne...
