Erythromycin (E-Mycin) is a Macrolide and Macrolide Antimicrobial. The physiologic effect of erythromycin is by means of Decreased Sebaceous Gland Activity.

Oxytetracycline (Terramycin) is a TETRACYCLINE analog isolated from the actinomycete STREPTOMYCES rimosus and used in a wide variety of clinical conditions.

Fervenulin is isolated from a nematicidal actinomycete Streptomyces sp. CMU-MH021 with nematicidal activity. It also inhibits egg hatch and J2 mortality of M. incognita (MICs: 30 μg mL and 120 μg mL, respectively).

Erythromycin thiocyanate acts by binding to bacterial 50S ribosomal subunits and inhibits RNA-dependent protein synthesis by blockage of transpeptidation and or translocation reactions, without affecting synthesis of nucleic acid .Erythromycin thiocyanate

K-252b, an indolocarbazole derived from the actinomycete Nocardiopsis, functions as a protein kinase C (PKC) inhibitor. It is effective in inhibiting extracellular kinases in cultured cells due to its inability to freely cross the cell membrane.

Toyocamycin (Vengicide) is an adenosine analog produced by Actinomycetes, functioning as an XBP1 inhibitor and inhibiting IRE1α-induced ATP-dependent XBP1 mRNA cleavage (IC50: 80 nM), and induces apoptosis.

Luisol A, an aromatic tetraol and anthraquinone antibiotic analog, serves as a significant metabolite produced by an estuarine marine actinomycete from the genus Streptomyces. Additionally, it functions as an ADC (Antibody-Drug Conjugate) cytotoxin [1].

Wychimicin C, a spirotetronate polyketide isolated from the rare actinomycete, Actinocrispum wychmicini strain MI503-AF4, demonstrates potent antibacterial efficacy. Specifically, it exhibits significant activity against methicillin-resistant Staphylococcus aureus (IC 50 =0.125-0.5 μg mL) and Enterococcus faecalis faecium (IC 50 =0.125-0.25 μg mL) [1] [2].

Wychimicin A, a spirotetronate polyketide isolated from the rare actinomycete Actinocrispum wychmicini strain MI503-AF4, exhibits potent antibacterial activity. Specifically, it demonstrates efficacy against methicillin-resistant Staphylococcus aureus (IC 50 = 0.125-0.5 μg mL) and Enterococcus faecalis faecium (IC 50 = 0.125-0.25 μg mL) [1] [2].

Nocarimidazole A, a white amorphous solid alkaloid exhibiting ultraviolet activity, can be isolated from the marine actinomycete Nocardiopsis [1] [2].

Gilvocarcin V, a metabolite from Actinomycete DO-38, exhibits potent antibacterial, antifungal, and antiviral activity.

Kibdelone A, a natural heterocyclic polyketide, was first isolated from the soil actinomycete Kibdelosporangium. It exhibits potent and selective cytotoxicity against various human tumor cell lines, in addition to showing significant antibacterial and nematocidal activity.

Tigloside (Actinotetraose hexatiglate), a symmetric tetrasaccharide esterified with tiglic acids, is identified as a secondary metabolite produced by the actinomycete strain Amycolatopsis [1].
