MICROCOCCIN P1

HCV; Bacterial; Parasite

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 (<10% inhibition at 30 mM) over a 40 h period for both the hepatic cell line HepG2 and the monocytic cell line THP-1, leading to a selectivity index greater than 500. Also investigats the intracellular activity of Micrococcin P1, it is active against GFP-expressing M. tuberculosis H37Rv growing inside RAW 264.7 macrophages with an IC ₈₀ of about 1 mM with potency comparable with that of isoniazid.
