Alternative sources of biologically active substances

Area of Science:

• Microbiology
• Natural Product Chemistry
• Drug Discovery

Background:

• Actinomycetes, nonfilamentous bacteria and fungi, are primary sources of clinically used antibiotics and bioactive substances.
• The continuous need for new therapeutic agents drives the search for novel metabolites from diverse microbial sources.

Purpose of the Study:

• To highlight the significance of actinomycetes in producing medically important compounds.
• To underscore the ongoing investigation of various microbial groups for new biologically active metabolites.

Main Methods:

• Review of literature on microbial production of bioactive compounds.
• Identification and characterization of metabolites from diverse microorganisms.

Main Results:

• Actinomycetes are established producers of a majority of antibiotics and other bioactive substances.
• Exploration of myxobacteria, pseudomonads, nocardias, basidiomycetes, marine microorganisms, enterobacteria, halobacteria, and hyperthermophiles is underway for novel metabolites.

Conclusions:

• Actinomycetes remain a cornerstone for antibiotic and bioactive compound discovery.
• Expanding the scope of microbial investigation is crucial for identifying new therapeutic agents.
