Biological Description

Chemical Properties

Storage & Solubility Information

Description	Nosiheptide (Multhiomycin), a thiopeptide antibiotic synthesized by Streptomyces actuosus, serves as a potent feed additive to promote animal growth. It functions by hindering bacterial protein synthesis and is distinguished by an indole side ring system and regiospecific hydroxyl groups on its macrocyclic core.
In vitro	Nosiheptide demonstrates non-toxic behavior towards mammalian cells at concentrations greater than 100 times the minimum inhibitory concentration (MIC) and retains its effectiveness against Staphylococcus aureus in the presence of 20% human serum. It is particularly potent against Enterococcus spp., the hypervirulent BI strain of Clostridium difficile, and displays remarkable activity against all tested strains of Staphylococcus aureus, including those resistant to multiple drugs (MIC values ≤ 0.25 mg/L). Additionally, Nosiheptide exhibits a significantly extended post-antibiotic effect against both healthcare- and community-associated Staphylococcus aureus when compared to vancomycin. Through time-kill studies, Nosiheptide has been found to quickly eliminate Staphylococcus aureus in a concentration- and time-dependent manner, achieving a near 2-log reduction at 6 hours with a concentration 10 times the MIC [1].
In vivo	Nosiheptide (20 mg/kg; intraperitoneal injection; injected at 1 and 8 h post-infection; female CD1 mice) offers obviously protection against mortality. Ten out of 10 of the Nosiheptide-treated mice remain alive on day 3, while 6/10 of the controls died on day 1[1].
