Napyradiomycin A1is a fungal metabolite originally isolated fromC. rubraand has diverse biological activities.1,2It is active againstS. aureus,M. luteus,B. anthracis,C. bovis, andM. smegmatis(MICs = 1.56-12.5 μg/ml).1Napyradiomycin A1is an estrogen receptor antagonist (IC50= 4.2 μM in rat uterine homogenates).2It also inhibits mitochondrial NADH:ubiquinone oxidoreductase (complex I) and succinate:ubiquinone oxidoreductase (complex II) activities in bovine heart homogenates (IC50s = 20 and 9.7 μM, respectively).3 1.Shiomi, K., Iinuma, H., Hamada, M., et al.Novel antibiotics napyradiomycins.

Nybomycin is a fungal metabolite originally isolated from Streptomyces sp. A717 and has antibacterial activity. It is active against B. subtilis, B. cereus, B. mycoides, M. smegmatis, and K. pneumoniae (MICs = 0.025, 2, 0.8, 0.2, and 0.003 μg/ml, respectively). Nybomycin is also active against M. tuberculosis and M. bovis (MICs = 4.5 and 1 μg/ml, respectively).

Decatromicin B is a bacterial metabolite that has been found in Actinomadura. It is active against Gram-positive bacteria, including several strains of S. aureus (MICs = 0.39-0.78 μg/ml), two strains of methicillin-resistant S. aureus (MRSA; MICs = 0.39 and 0.78 μg/ml), as well as M. luteus, B. subtilis, and C. bovis (MICs = 0.78, 0.78, and 6.25 μg/ml, respectively).

Imidocarb dihydrochloride monohydrate is an effective antiprotozoal agent against the parasite B. bovis (IC50: 87 μg ml).

Imidocarb dipropionate is an antigenic insecticide, is active against the protozoan parasite B. bovis (IC50 : 0.87 µg ml).

Imidocarb, a potent antiprotozoal agent, exhibits activity against the parasite B. bovis with an IC₅₀ of 87 μg mL [1].
