Anti-inflammatory cytokines have an important role in the development of inflammatory reactions. If an acute inflammation turns into chronical it is very often a pathological phenomenon. Chronicle inflammations accompany a whole number of serious diseases with an unclear prognosis, such as some of the autoimmune diseases. Usually, the cause of these diseases is not quite clear and the treatment is mainly symptomatic with an effort to suppress the immunity system. For this purpose we use various immunosuppressant drugs, and biological treatment is used, too. Another possibility is to use bioactive secondary metabolites produced by various microorganisms. In this group there are for example macrolides antibiotics, and a big potential is also seen in the recently discovered polyketides. The objective of this work is to test the newly acquired secondary metabolites that were isolated in the Laboratory of Molecular Biology of Actinomycetes at the Czech Academy of Sciences. Tested were manumycin A, manumycin B, colabomycin E, asukamycin A, asukamycin D, β-rubromycin, deoxynybomycin. As comparative substances were used the macrolides antibiotics clarithromycin and azithromycin dehydrate, all of them commercial pharmaceuticals. These substances were tested on the monocytic line THP-1. Cells were stimulated...
