Manumycin-type metabolite called Colabomycin E which inhibits caspase 1 and creation of interleukins, strain produces the Colabomycin E and a method of a production of the Colabomycin E

Номер: US20160168106A1

A manumycin-type metabolite called Colabomycin E which inhibits caspase 1 and creation of interleukins, strain produces the Colabomycin E and a method of a production of the Colabomycin E. Colabomycin E is a new member of the manumycin-type metabolites produced by the strain Streptomyces aureus SOK1/5-04 deposited in The Czech collection of microorganisms under number CCM8556. The structure of 5 is similar to that of the already known metabolite colabomycin A (3) isolated from Streptomyces griseoflavus . However, the upper polyene chain of 5 is two carbons longer. Therefore, it was named Colabomycin E. Biological activity assays indicated that colabomycin E significantly inhibited IL-1β release from THP-1 cells and might thus potentially act as an anti-inflammatory agent.
