Meleagrin is an antibiotic.
Meleagrin is an antibiotic derived from a deep ocean, penicillin-producing P. chrysogenum.
In vitro: It was found that consistent with their selective inhibition of Staphylococcus aureus FabI, meleagrin and its more active derivatives could directly bind to S. aureus FabI that was measured in a fluorescence quenching assay, inhibit intracellular fatty acid biosynthesis and growth of S. aureus, and increase the minimum inhibitory concentration (MIC) for fabI-overexpressing S. aureus. The compounds that were not effective against the FabK isoform, however, were able to inhibit the growth of Streptococcus pneumoniae containing only the FabK isoform. In addition, no resistant mutant to these compounds was obtained. Notely, fabK-overexpressing Escherichia coli was found to be not resistant to these compounds, but was resistant to triclosan . Another study found that meleagrin was able to inhibit the growth of the human breast cancer cell lines, while similar treatment doses had no effect on the growth and viability of the non-tumorigenic human mammary epithelial cells MCF10A. Meleagrin also displayed good ATP competitive c-Met inhibitory activity in Z-Lyte assay .
In vivo: Up to now, there is no animal in vivo data reported.
Clinical trial: So far, no clinical study has been conducted.

Meleagrin inhibited the growth of human breast cancer cells MDA-MB-231, MDA-468, BT-474, SK BR-3, MCF7 and MCF7-dox. It was also found that similar therapeutic had no effect on the growth and viability of non-tumorigenic human mammary epithelial cells MCF10A. Meleagrin also showed excellent ATP-competitive c-Met inhibitory activity in Z-Lyte analysis, which had been further confirmed by molecular docking studies and Western blot analysis.
