Thiocillin I is a thiopeptide antibiotic and has in vitro antibacterial activity against Gram-positive bacterial strains(MIC of Thiocillin I against S. aureus 1974149, E. faecalis 1674621, B. subtilis ATCC 6633 and S. pyogenes 1744264 are 2 μg/mL, 0.5 μg/mL, 4 μg/mL and 0.5 μg/mL, respectively).
DNA gyrase/Topo IV-IN-2 (Compound AK19) 是一种抗菌剂,对 E. coli DNA 旋转酶与拓扑异构酶 IV 的IC50分别为 0.783 μM和 7.136 μM。它对革兰氏阳性与革兰氏阴性病原体呈现广谱抗菌活性,并能抑制 B. subtilis 和 MRSA 的生物膜,其对 B. subtilis 和 MRSA 的MIC为 1.9 μM。此化合物适用于研究抗耐药菌药物。
Frequentin, an antibiotic originally isolated from P. frequentans, is active against bacteria (MICs = 200 and 300 µg/ml for B. subtilis and S. aureus, respectively) and fungi.
Violacein is a bacterial metabolite originally isolated from C. violaceum that has antibacterial and antiprotozoal activities.[1] [2] It is produced by C. violaceum as a purple pigment in response to N-hexanoyl homoserine lactone , a property that has been modified to create a strain of C. violaceum used in detecting quorum-sensing molecules.[3] Violacein is active against Gram-positive bacteria, including B. subtilis and S. aureus (MICs = 0.8 and 1.6 µM, respectively). It is also active against P. falciparum, including chloroquine-susceptible and -resistant strains (IC50s = 0.85 and 0.63 µM, respectively).[2] It reduces parasitemia in a mouse model of nonlethal P. chabaudi chabaudi infection when administered at a dose of 7.5 mg/kg and increases survival in a mouse model of lethal P. chabaudi chabaudi infection. Violacein permeabilizes the cytoplasmic membrane of bacterial cells but does not affect the cell wall.[1]
Flumequine-13C3 is intended for use as an internal standard for the quantification of flumequine by GC- or LC-MS. Flumequine (T1060) is a fluoroquinolone antibiotic.1It is active againstS. aureus,S. pyogenes,B. subtilis,E. coli,P. aeruginosa,S. faecalis,andK. pneumoniae (MICs = 1-100 μg/ml). Flumequine (T1060) is also active against field isolates of B. hyodysenteriae (MICs = 6.25-200 μg/ml).2It inhibits DNA gyrase,disrupting supercoiling of bacterial DNA to block transcription and replication.3
Deoxyviolacein is a bacterial metabolite and byproduct in the biosynthesis of the bisindole alkaloid violacein that has anticancer, antibacterial, and antifungal properties. It inhibits proliferation of hepatocellular carcinoma cells when used at concentrations ranging from 0.1 to 1 μM. Deoxyviolacein (125 μg/ml) has antibacterial activity against Gram-positive bacteria, including S. aureus, B. subtilis, and B. megaterium. It also has antifungal activity against R. solani when used at a concentration of 2 mg/ml.
17-hydroxy Venturicidin A is a macrolide fungal metabolite originally isolated from Streptomyces. It has antibiotic activity against M. luteus, B. subtilis, and S. aureus and antifungal activity against V. dahlia, Fusarium, and C. tropicalis in a disc assay.
