Fungal Phylum Basidiomycota01:26

Fungal Phylum Basidiomycota

217
Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Adrenergic Agonists: Chemistry and Structure-Activity Relationship

3.3K
Adrenergic agonists' structure-activity relationship (SAR) determines their selectivity and efficacy. These agonists comprise a phenylethylamine moiety with an aromatic ring and an ethylamine side chain.
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of...

Area of Science:

  • Mycology
  • Pharmacognosy
  • Medicinal Chemistry

Background:

  • The genus *Phellinus* is known for diverse bioactive compounds.
  • European fungal species offer a rich source for novel therapeutic agents.
  • Understanding the chemical and biological profiles of these fungi is crucial.

Purpose of the Study:

  • To evaluate the chemical potential and biological properties of European *Phellinus* fungal species.
  • To screen extracts for antimicrobial and antioxidant activities.
  • To identify promising species for further investigation and potential drug development.

Main Methods:

  • Collection and identification (morphological and genetic) of 30 *Phellinus* samples from various European locations.
  • Preparation of methanol extracts and screening for antimicrobial activity against bacterial and fungal strains.
  • Assay of antioxidant activity using DPPH and ABTS methods.
  • Chemical profiling using Gas Chromatography-Mass Spectrometry (GC-MS) and analysis of thermal decomposition and spectroscopic properties.

Main Results:

  • Thirty methanolic extracts were screened for biological activities.
  • Significant antimicrobial activity was observed against tested bacterial and fungal strains.
  • Antioxidant potential was confirmed through DPPH and ABTS assays.
  • *Phellinus igniarius*, *Fomitiporia robusta*, and *Porodaedalea pini* were identified as the most biologically active species.
  • GC-MS analysis provided insights into the chemical composition of the extracts.

Conclusions:

  • Selected European *Phellinus* species possess notable antimicrobial and antioxidant properties.
  • The identified active compounds warrant further research for pharmaceutical applications.
  • This study supports the ethnobotanical use of these fungi and their potential in combating antibiotic resistance.
