In order to collect 45722s, a separation means usually used for collecting from metabolites produced by microorganisms is appropriately used. BE-45722 is present in the culture filtrate and in the bacterial cells, so that it can be separated from the culture filtrate or the bacterial cells by a conventional separation means,
For example, it can be purified by a solvent extraction method, an ion exchange resin method, an adsorption or partition chromatography method, a gel filtration method, etc., alone or in combination. Further, high performance liquid chromatography, thin layer chromatography and the like can be appropriately used for extraction and purification. Preferred examples of separation and purification include the following methods. First, the culture solution is filtered,
Obtain bacterial cells. The obtained bacterial cells are extracted with an organic solvent such as methanol or acetone. The crude extract thus obtained was partitioned between water and ethyl acetate, and the extract obtained after distilling off ethyl acetate was used as Sephadex LH-2.
Gel filtration through 0 column (eluted with methanol). The fraction containing BE-45722s was concentrated under reduced pressure, and the residue was further purified by high performance liquid chromatography using a reverse phase column to give BE-4.
5722 type can be obtained as a white powder. When the compound of the present invention is used as an antibacterial agent, it is also used as a pharmaceutically acceptable salt of the compound. Typical examples of pharmaceutically acceptable salts include salts with inorganic bases such as caustic soda and caustic potash.
