  A series of six isopimarane-type diterpene glycosides, along with an eremophilane-type sesquiterpene, i.e., elaeicolasides A-C (1-3, resp.), 16-(α-D-mannopyranosyloxy)isopimar-7-en-19-oic acid (4), hymatoxin K (5), hymatoxin L (6), and elaeicolalactone (7), were isolated from the AcOEt extract of the fermented broth of Stilbohypoxylon elaeicola YMJ173. Among these, 1-3 and 7 are new compounds based on their spectroscopic data and sugar composition analysis. The effects of 1-7 on the inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-activated murine macrophage RAW264.7 cells were evaluated. All these compounds inhibited NO production, detected as nitrite in the culture medium, in activated macrophages without any cytotoxicity at a concentration of 100 μM. Among these compounds, 2 showed a significant activity with the average maximum inhibition (E(max)) and median inhibitory concentration (IC(50)) values of 93.3±0.5% and 79.3±0.4 μM, respectively.

  Background: Natural products acquire vast and intriguing structural diversity and have been recognized as a tremendously diverse source of new lead compounds. Numerous bioactive secondary metabolites are present in the form of glycosylated molecules in which the sugar parts are normally associated with the interaction along with molecular recognition of the cellular target. Scope and approach: The presence of sugar entities are crucial as well as in some cases necessary, for therapeutic effects. Establishing novel and potent glycosylated secondary metabolites has formed a main goal in the natural product field from fungi and bacteria. These compounds possess a diverse range of sugar units. Key findings and conclusions: Fungi is considered one of the important sources for approved drugs with a diverse range of mode of action. The sugar part in numerous pharmacologically active natural products enhances bioavailability, biological potential, reduce toxicity, and improve stability. The vast majority of glyocosides showed antimicrobial effects, cytotoxic, antiviral and antiinflammatory effects. Notably, numerous fungal glycosides presented in this review illustrate significant antimicrobial effects towards various microorganisms especially against plant pathogens. The antimicrobial effects of these fungal glycosides indicate that these metabolites could be employed as natural preservatives in food in order to abolish or control the growth of pathogenic and spoilage microorganisms.
