Cell wall the cell membrane is the bacterial cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria, although L-form bacteria can be produced in the laboratory that lack a cell wall. The antibiotic penicillin is able to
Micafungin via weak CYP3A4 inhibition. Micafungin is a natural antifungal product derived from other fungi as a defense mechanism for competition of nutrients, etc. To be specific, micafungin is derived from FR901379, and is produced by "Coleophoma empetri". Micafungin Micafungin (trade name Mycamine) is an echinocandin antifungal drug used to treat and prevent invasive fungal infections including candidemia, abscesses and esophageal candidiasis. It inhibits the production of beta-1,3-glucan, an essential component of fungal cell walls. Micafungin is administered intravenously. It received final approval from the U.S. Food and Drug Administration on March 16, 2005, and gained approval in the European Union
