Pharacine

CAS: 63440-93-7

Pharacine is an antibiotic, which is derived from natural sources with a mode of action that inhibits bacterial protein synthesis. This product targets the 50S ribosomal subunit of bacteria, effectively hindering the translocation steps, thereby preventing the growth and proliferation of the bacterial cells. Pharacine's unique mechanism allows it to be a potent agent against various gram-positive and some gram-negative bacteria.
