Bioactive Metabolites
On Bioactivity
Bioactivity refers to antimicrobial, antitumor, antiviral, pharmacological, and similar activities. Such functions are generally not associated with structures or producer species or pathways.

The number of bioactive natural products is estimated around 200000 to 250000.
Approximate number of known natural products[1]

In actinomycetales, the rare actinos produce most diverse and unique compounds.
- Exclusively rare actinos
- All known glycopeptide antibiotics (about 120) and most orthosomycins are produced exclusively by rare actinos.
- Exclusively actinomycetales
- All known macrolides, polyene antibiotics, aminoglycosides, anthracyclines are produced exclusively by actinomycetales.
- Known small categories such as:
- polyether antibiotics (-250),
- novobiocin related glycosidic antibiotics, streptothricins, actinomycins, echinomycin-like quinoxalin peptides (80-120 each),
- elfamycins, glutarimides, orthosomycins (50-60 each)
