| Bioactivity | Micrococcin P1 is a macrocyclic peptide antibiotic and is a potent hepatitis C virus (HCV) inhibitor with an EC50 range of 0.1-0.5 μM[1]. Micrococcin P1 has in vitro antibacterial activity against Gram-positive bacterial strains. The MIC values of Micrococcin P1 against S. aureus 1974149, E. faecalis 1674621 and S. pyogenes 1744264 are 2 μg/mL, 1 μg/mL and 1 μg/mL, respectively[2]. Micrococcin P1 is also a potent inhibitor of the malaria parasite Plasmodium falciparum[3]. | |||||||||

| Invitro | Dose-response assays reveales Micrococcin P1 to be very potent with a minimal inhibitory concentration (MIC) of 32-63 nM. Cytotoxicity assays reveales no significant impairment on cell line growth (M. tuberculosis H37Rv growing inside RAW 264.7 macrophages with an IC80 of about 1 mM with potency comparable with that of isoniazid[1]. | |||||||||
