Suillin: A mixed-type acetylcholinesterase inhibitor from Suillus luteus which is used by Saraguros indigenous, southern Ecuador

Suillus luteus (L.) Roussel is an edible mushroom commonly known as slippery jack or “Kallampa” by indigenous people from Loja province. It is used in traditional medicine to manage gastrointestinal

Structures and Biological Activities of Alkaloids Produced by Mushrooms, a Fungal Subgroup

This review covers the findings of the last 20 years related to the isolation, structures, and biological activities of the alkaloids produced by mushrooms, a fungal subgroup, and their potential to develop drugs and agrochemicals.

Impact of substrate supplemented with CaCO3 on mycelial growth, yield, morphological features and storability of fruiting bodies of black poplar mushroom Agrocybe cylindracea (DC.) Marie.

Black poplar mushroom, Agrocybe cylindracea deserves special attention, due to its medicinal properties. Water and alcohol extracts from fruiting bodies of the fungus have an anti-oxidant,

Actual Concepts of Higher Fungi’s Toxins: Simple Nitrogen-Containing Compounds

Abstract Higher fungi represent a group of living organisms that remain poorly studied in terms of mycology and biochemistry. Among their secondary metabolites, toxic compounds are of particular



Brunneins A–C, β-Carboline Alkaloids from Cortinarius brunneus

Four beta-carboline alkaloids, brunneins A-C (1-3) and 3-(7-hydroxy-9H-beta-carboline-1-yl)propanoic acid (4), were isolated from fruiting bodies of the agaricoid fungus Cortinarius brunneus. The

Effect-Directed Discovery of Bioactive Compounds Followed by Highly Targeted Characterization, Isolation and Identification, Exemplarily Shown for Solidago virgaurea.

A nontargeted, effect-directed screening (bioprofiling) and a subsequent highly targeted characterization of antibacterial compounds from plant matrices is demonstrated on the example of Solidago

New indole derivatives with free radical scavenging activity from Agrocybe cylindracea.

Two new indole derivatives were isolated as free radical scavengers from the MeOH extract of Agrocybe cylindracea and inhibited lipid peroxidation in rat liver microsomes.

HPLC-DPPH Screening Method for Evaluation of Antioxidant Compounds in Corylus Species

Comparison of in vitro DPPH scavenging activity of the Corylus extracts prepared with ethyl acetate and methanol to those of well-known antioxidant phenolics was performed to investigate the contribution of certain compounds to the total antioxidant activity.

The present review analyzes the pecularities of polysaccharides derived from fruiting bodies and cultured mycelium in selected examples of medicinal mushrooms and concludes that high molecular weight glucans appear to be more effective than those of low molecular weight.

A Circular Dichroism Study of Molecular Association of Cinchona Alkaloids and Carboxylic Acids

Circular dichroism (CD) spectra of cinchona alkaloids and their salts with carboxylic acids have been investigated. A eontribution of the exciton type Cotton effect to the 230 nm CD band of free
