Description
It is produced by the strain of Actinomadura paroosalo. It's a glycopeptide antibiotic. It has inhibitory effect on Staphylococcus aureus, Staphylococcus furfur, Staphylococcus hemolyticus and enterococcus faecalis. The terminal branching activity of lipid chains is greater than straight chains (C1>C2>C3>C4, B1>B2), and the chain length is greater than short chains (C2>B). It acts by inhibiting the synthesis of bacterial cell wall.

1. Parvodicin, a novel glycopeptide from a new species, Actinomadura parvosata: discovery, taxonomy, activity and structure elucidation
S B Christensen, H S Allaudeen, M R Burke, S A Carr, S K Chung, P DePhillips, J J Dingerdissen, M DiPaolo, A J Giovenella, S L Heald, et al. J Antibiot (Tokyo). 1987 Jul;40(7):970-90. doi: 10.7164/antibiotics.40.970.
An extensive taxonomic investigation identified strain SK&F-AAJ-271 as a new species, designated Actinomadura parvosata. Fermentations of this organism produce a complex of acidic, lipophilic glycopeptide antibiotics, the parvodicins. Structures for seven of the isolated components were derived from a combination of mass spectral, high-field NMR and chemical techniques. The O-acetyl functionality present in two of the isolated components is a structural feature unique among the known members of this class of antibiotics. The parvodicins are active in vitro against a range of Gram-positive bacteria. The most active parvodicin, C1, produces high serum levels in vivo and has the potential for a long duration of action.
